Definitions
- the invention relates to a method for examining chemical and / or biological samples, in particular in high and medium throughput screening.
- the invention further relates to a microscope for carrying out the method, as is used in particular in fluorescence spectroscopy.
- the processes taking place in an observation volume are optically recorded with microscopes.
- Known confocal microscopes have an illumination unit, such as a laser, for generating an observation beam, in particular an excitation light.
- the excitation light strikes a dichroic mirror, which reflects the light in the direction of the observation volume.
- the light then passes through a lens system, in particular a microscope objective, from which the excitation light is focused in the observation volume.
- the excitation light for example fluorescence
- the resulting fluorescent light passes through the microscope objective and through the dichroic mirror to a detector unit.
- the detector unit can be an aperture diaphragm upstream, in which the fluorescent light is focused, so that a confocal microscope is formed.
- Another possibility is to move the excitation light beam.
- To move the light beam it is known to provide one or more mirrors in the beam path of the microscope that can be tilted back and forth via a suitable drive mechanism. By providing two mirrors, it is possible to move the light beam within one plane of the observation volume.
- Such arrangements have the disadvantage that the tilting movement of the mirror has a dead center, so that the movement of the light beam is braked and accelerated. This leads to an uneven excitation of the ensemble within the sample and thus to a falsification of the measurement results. This is due in particular to the fact that the fluorescence molecule is longer at the dead center is irradiated and thus can emit more photons or the molecule is bleached more.
- microscopes with tiltable mirrors have the disadvantage that the light beam passes through the objective at different angles to the optical axis of the microscope objective. This results in an optical error that changes depending on the inclination of the tilt angle, which in turn has a negative influence on the measurement results. Furthermore, the focus of an obliquely guided light beam through the microscope objective becomes oval. The shape of the focus also changes depending on the position of the tilting mirror. This also leads to a falsification of the measurement results.
- the object of the invention is to provide a method for examining chemical and / or biological samples, in particular for high and medium throughput screening, with which it is possible to move the focus through the observation volume while improving the measurement results. Furthermore, it is an object of the invention to provide an apparatus for performing the method.
- the movement of the observation beam is essentially continuous.
- the movement of the The observation beam, or the excitation light thus takes place in the observation volume of the sample without a reversal of direction, which leads to considerable braking and acceleration of the movement of the light beam.
- This homogenization of the movement of the light beam in the observation volume results in a considerable homogenization of the excitation when examining samples which are to be excited to fluorescence. This prevents, for example, the destruction of fluorescent markers by increased excitation.
- the quality of the measurement results can be considerably improved by moving the observation beam uniformly through the observation volume.
- Another advantage of the method according to the invention is that with constant or even movement of the observation beam through the sample, fluctuation times of individual particles, such as molecules (FIMDA measurements), can be carried out better. This is because the speed of movement of the observation beam must be taken into account when determining the fluctuation times. A constant or approximately constant speed of the motion beam is considerably easier to take into account here. Furthermore, the observation times for each particle are evened out. This means that, for example, the same amount of information is recorded from each particle. This significantly improves the statistical quality of the data.
- FIMDA measurements fluctuation times of individual particles, such as molecules
- the observation beam can be a beam generated by an illumination device, such as a laser, which is moved evenly in the sample by the method according to the invention. This is, for example, excitation light.
- the observation beam can also be the beam path of the observation. The beam path runs in the opposite direction.
- that observed by a detector Area in the sample is moving.
- the fluorescence of a sample, ie radiation emitted by the sample is observed.
- the movement of the observation beam is preferably unidirectional. Reversing the direction of movement is thus avoided. As a result, large fluctuations within the illumination volume of the amount of photons generated or observed, i.e. Fluctuations in different lighting or observation locations are avoided.
- the quantity of photons is understood to mean the number of photons generated or emitted per location. The amount of photons is therefore the intensity integrated over time. With a constant speed of movement of the observation beam in the sample, the dwell time of the beam at each location of the sample is constant or fluctuates within considerably lower limits than in known methods. This can significantly improve the quality of the measurement results.
- the illumination beam is preferably moved on a self-contained path, preferably an elliptical path, and particularly preferably an essentially circular path.
- a deflection mirror which can be rotated about an axis of rotation.
- the axis of rotation includes an angle ⁇ 90 ° with the surface of the deflection mirror.
- the resulting wobble movement of the deflection mirror moves the observation beam along an elliptical path in the observation volume.
- different dwell times at individual illumination locations within the observation volume are considerably reduced compared to a back and forth movement of the observation beam.
- the speed of movement of the observation beam in the observation volume is not constant. In the area of the apex of the ellipse in particular, the observation beam has a slower speed.
- the rotational speed is set in such a way that the observation beam in the observation volume has a speed which fluctuates at most within narrow limits.
- the speed is preferably substantially constant.
- the observation beam or excitation beam in order to equalize the illumination intensity acting on different illumination locations in the sample, which is particularly dependent on the dwell time, i.e. the speed of movement, the observation beam or excitation beam varies, thereby causing the intensity of the observation beam to be controlled as a function of the movement speed.
- the quantity of photons generated by the observation beam is evened out by speed-dependent control of the illumination intensity.
- the intensity of the observation beam is thus reduced when the observation beam moves relatively slowly in the observation volume. This also enables the measurement results to be made more uniform. In particular in the case of measurements based on fluorescence, this can achieve that the individual particles are excited uniformly. This avoids falsifying the measurement results due to uneven excitation or destroying the fluorescent markers.
- the control of the intensity of the observation beam which can be done, for example, by time-dependent modulation of a laser, is an independent invention that is independent of the continuous one Movement of the observation beam is.
- the illumination intensity can be made more uniform by appropriately controlling the intensity of the illumination beam.
- a combination of the speed variation and the variation of the illumination intensity for the purpose of homogenization is particularly preferred. This has the advantage that the speed of the rotating deflecting mirror, for example, only has to be varied slightly, so that the moments of inertia that occur do not become too high. Varying the intensity of the illumination beam is also much easier to implement with minor adjustments than with large fluctuations.
- the lighting intensity can also be adjusted, for example, using filters that can be adapted to the shape of the web.
- the microscope has a deflection mirror which deflects an observation beam, such as an excitation light, generated by an illumination unit. This moves the focus in the observation volume. Instead of a tilting movement, the deflection mirror performs a wobble movement according to the invention. As a result of the wobble movement, the focus is moved along a closed path in the observation volume. The movement is therefore continuous. A complete braking and subsequent acceleration of the light beam, as occurs in tilting mirrors, is not the case with a mirror that performs wobbling movements. Furthermore, the design of the microscope according to the invention can be realized at a considerably lower cost than the provision of tilting mirrors or so-called galvo scanners, which have complex drive and control electronics.
- a microscope according to the invention for performing the method can only be used to observe the sample. With such a microscope, no beam generated by an illumination unit would be set in a wobble motion.
- the wobble mirror or another suitable device serves to move the point in the sample observed by an observation detector.
- the wobble movement can be caused, for example, by a three-point mount on the back of the mirror.
- the mirror can be made to wobble by moving the individual images.
- the mirror is rotated about an axis of rotation.
- the deflection mirror encloses an angle not equal to 90 ° with the axis of rotation.
- the rotation of the mirror alone results in a wobble movement and, as a result, a corresponding movement of the light beam in the observation volume.
- the angle of the deflection mirror with respect to the axis of rotation is in the range from 90.1 ° to 95 °, preferably 90.1 ° to 92 °, particularly preferably 90 , 1 ° - 91 °.
- a circular movement can preferably be brought about in a mirror performing a wobble movement in that the beam path is parallel to the axis of rotation.
- the deflection mirror is preferably moved such that the focus in the observation volume is moved on a closed path.
- the wobble movement depending on the surface of the mirror and the point of reflection of the light beam on the mirror relative to the center of the wobble movement must be taken into account.
- good measurement results can be achieved in that the excitation light strikes the mirror essentially in the center of rotation of the deflection mirror.
- Such an arrangement has the advantage that the light beam always passes the measurement lens at the same distance from the center axis of the measurement lens.
- the deterioration of the focus compared to a light beam passing through the lens in the lens axis is therefore essentially constant and can therefore be compensated for in a targeted manner, for example by an adjusted adjustment. Since there is no change in the focus depending on the position of the mirror or the position of the focus in the sample, the measurement results that can be achieved are considerably improved.
- the angle of the mirror with respect to the axis of rotation or with respect to the light beam striking the deflection mirror is preferably adjustable.
- an adjustment unit for the automatic adjustment of the angle of the deflection mirror is provided for this purpose.
- This has the advantage that, for example, the angle of the deflection mirror and thus the path of the focus in the sample can also be changed during the examination of a sample.
- the radius of the Circular movement of the focus or the main axes of the ellipse in which the sample is changed In this way it is possible to completely scan the sample in one plane.
- Another way of completely scanning a sample in one plane is to keep the angle of the deflection mirror constant during the examination so that the focus moves on a constant path.
- the table from which the sample to be examined is held is also moved.
- the movement of the table can be one-dimensional or two-dimensional. Furthermore, it is possible to combine the above two methods for scanning a sample, in particular in one plane, if the confocal principle is used.
- the existing dichroic mirror serving as a beam splitter in such a way that it serves as a deflection mirror and can be set into a suitable wobble movement.
- the dichroic mirror is preferably mounted in a link guide. The rotation takes place from the outside so that the beam path is not impaired. Since such a movement of the beam splitter also leads to a corresponding movement of the image imaged on the detector, a surface sensor, for example a large-area photodiode, is preferably used as the detector in this embodiment. With the aid of a large-area photodetector, the detector surface can be read out in an integrated manner with a non-confocal microscope, since the light incident on the detector generates the same signal regardless of the location at which it hits the detector.
- the microscope described above is in particular a confocal microscope.
- the Measurement results can be significantly improved by using the deflection mirror according to the invention.
- the deflection unit has a deflection mirror connected to a drive unit, which can be set in a wobble movement by the drive unit.
- the deflection unit is an additional component that can be connected with a conventional microscope.
- the deflection unit preferably has a housing carrying the drive unit and / or the deflection mirror.
- the housing has a connection element for connecting to a lens mount of a microscope and a mounting element for mounting a microscope lens. It is thus possible, for example, to remove the microscope objective in a conventional microscope, instead to insert the deflection unit into the objective holder and to fasten the previously removed microscope objective to the receiving element of the housing.
- a conventional microscope can easily be converted by the deflection unit to a microscope according to the invention with a mirror that performs a wobble movement.
