Definitions
- the invention relates to an optical system for use in an underwater environment.
- Optical systems in particular (camera) lenses that are used in underwater environments, have to withstand high pressures that act on the optical systems depending on the depth.
- Mechanical-optical-electrical systems are usually encapsulated against the water in the underwater environment by a housing in which quasi-constant (gas) pressure conditions prevail.
- Optical systems that are to visually capture the surroundings or parts of the surroundings require an optically transparent interface to the surroundings (also called an optical port) in the housing.
- the optical port has an optically transparent component made of an optical one
- optically transparent component that is in direct contact with the underwater environment.
- the optically transparent component must therefore withstand high pressures of the underwater environment and pressure changes depending on the depth of the dive.
- optically transparent component In previously known optical systems for use in an underwater environment, the functional requirement for the optically transparent component is primarily based on the mechanical load-bearing capacity, i.e. limited to the mechanically sufficiently stable demarcation of the interior of the housing from the surrounding medium with the most neutral possible optical imaging effect.
- Embodiments of the optically transparent component contained in the prior art are flat plates or concentric menisci /
- Dome optics which are held and supported on flat or conical design elements (e.g. 45 ° half opening angle) towards the housing.
- the optically transparent component of optical systems in the prior art is used as an additional component which negatively influences / does not promote the optical imaging properties.
- the optically transparent component must offer sufficient opening for the imaging properties required by the optical imaging system.
- the optically transparent component of the optical port, and thus its surface exposed to the ambient pressure are always larger than that
- optically transparent component is an additional required element in the system, which is heavily loaded by the external pressure, since it generally. significantly larger than the functionally necessary dimensions of the first lens of an optical
- Imaging system must be in order to offer this enough opening, is technically complex to manufacture, especially in the case of variants set at the edge, and the optically neutral effect is only achieved to a limited extent.
- the invention is based on the object of demonstrating an optical system for use in an underwater environment which has a high mechanical load-bearing capacity and has good optical properties and is technically simple to produce.
- the object is achieved by an optical system for use in an underwater environment, wherein the optical system is a housing that a
- Interior of the optical system is watertight from the environment, and comprises a lens with an outer surface, the housing having a frame, the lens being received in the frame such that when the optical system is in the underwater environment, the outer surface with is in fluid contact with the water of the underwater environment, the outer surface of the lens having an arched shape, in particular a convex shape, preferably a spherical-convex shape Form, wherein the lens has a first (concave or convex) curved, in particular spherical, contact surface and the holder has a second contact surface, the lens being arranged in the holder such that the first contact surface presses against the second contact surface when the Pressure around the optical system is higher than the pressure inside the optical system.
- optical system can be an optically active component. This can reduce the number of parts of the optical system and increase the optical performance of the optical system. The dimensions of the lens or the outer surface of the lens and thus its surface exposed to the external pressure can be reduced to the dimension that is optically functionally required. In addition, the optical system has very good optical properties because the lens used in the

- the first contact surface can be manufactured inexpensively with particularly high precision.
- the first contact surface can be produced in a technically simple, precise manner using conventional optical methods and measured using standard measuring methods, and the quality of the first contact surface can be assessed.
- the first contact surface can touch / contact the second contact surface directly or directly, or an intermediate layer made of an additional material, e.g. made of a material that is not the same as the material of the lens and the material of the frame, between the first contact surface and the second contact surface.
- the first contact surface can touch only a part of the second contact surface or, in the underwater environment, a part of the first contact surface can press against the second contact surface or a part of the second contact surface.
- the center of the spherical shape of the first contact surface lies on an optical axis of the lens.
- the lens has an inner surface opposite the outer surface, an optical axis of the lens running through the outer surface and the inner surface, and the inner surface of the lens has an arched shape, in particular a concave shape, preferably a spherical-concave shape .

- the first contact surface of the lens has a convex shape
- the second contact surface of the mount has a concave shape with one

This results in a particularly large-area contact between the first contact area and the second contact area. Thus, the forces arising from the pressure of the underwater environment can be transferred to the socket with little tension.
- the second contact area can e.g. can be produced by conventional machining processes.
- the first contact surface of the lens that is produced can be produced in a technically simple manner using standard optical manufacturing processes and can be measured and evaluated very precisely with the aid of conventional measuring technology from the manufacture of optical parts.

- the advantage of this is that the imaging quality of the optical system remains unchanged even when the lens or the mount is displaced due to loading at high pressures.
- the further optical elements are moved together with the lens, so that the distances between the further optical elements and the lens do not change.
- the first contact surface of the lens is polished and / or etched.
- deep damage or microcracks or crack nuclei in the first contact area can be technically simply reliably removed or avoided / minimized.

- the optical system further comprises a seal for sealing an area between the first contact surface of the lens and the second contact surface of the mount.
- a seal for sealing an area between the first contact surface of the lens and the second contact surface of the mount. In this way, the ingress of water is prevented safely and technically even at high ambient pressures.
- the contact between the first contact surface and the second contact surface is independent of the seal. This further increases the reliability of the optical system.

- the optical system 10 can e.g. can be used for an underwater camera or can be an underwater camera.
- the lens 20 represents an optical port, which forms an optically transparent connection through the housing between the interior 60 and the environment 50. In this way, light from the environment 50 can enter the housing.
- the lens 20 has an outer surface 24 which is designed to contact the water. This means that water contacts the outer surface 24 of the lens 20 when the optical system 10 is in an underwater environment.

- the first contact surface 28 can press against the second contact surface 48 with a force that corresponds to a pressure of approximately 50 bar or approximately 100 bar on the outer surface of the lens, while only normal pressure presses on the outer surface of the lens 20.
- the first contact surface 28 of the lens 20 can be pressed against the second contact surface 48 by means of a screw ring 35 or a preload ring or a securing ring, even if the pressure of the environment 50 corresponds to the pressure in the interior 60 of the optical system 10 (for example if the optical System is outside the underwater environment).
- the screw ring 35 is partially arranged with an intermediate element on the outer surface 24 of the lens 20.
