EMI2.1
K bedeutet das Verhältnis der Eintrittspupille zur Brennweite des Aufnahmeobjektivs.
T ist der optische Abstand des selektiven Farbenfiltefs vom Film im Aufnahmeapparat.
Der Wert von F ist durch die Projektionsbedingungen in einem bestimmten Raum oder Saal festgelegt.
Der Wert von D ist durch die Gleichung 4 bestimmt. e und (6 sind unter Erwägung bequemer baulicher Ausführung der Apparate und Objektive zu wählen bzw. hängen hievon ab.
Es bleiben also drei Gleichungen mit den drei Unbekannten f1, f2 und E.
In einem ganz besonderen Fall liefern diese Gleichungen die folgenden Werte :
EMI2.2
<tb>
<tb> F <SEP> = <SEP> 200 <SEP> mm <SEP> E <SEP> = <SEP> 190 <SEP> nnn
<tb> fi <SEP> = <SEP> 300mm <SEP> a <SEP> -= <SEP> 27 <SEP> Mm
<tb> f2 <SEP> = <SEP> 220 <SEP> mm <SEP> e <SEP> = <SEP> 73 <SEP> mm
<tb>
Dieses Beispiel entspricht dem Fall, dass man einen kollimatierten Film und ein Aufnahmeobjektiv

EMI2.1
K means the ratio of the entrance pupil to the focal length of the taking lens.
T is the optical distance of the selective color filter from the film in the recording device.
The value of F is determined by the projection conditions in a particular room or hall.
The value of D is determined by Equation 4. e and (6 are to be selected with consideration of the convenient structural design of the apparatus and lenses, or depend on them.
So there are three equations with the three unknowns f1, f2 and E.
In a very special case, these equations give the following values:
EMI2.2
<tb>
<tb> F <SEP> = <SEP> 200 <SEP> mm <SEP> E <SEP> = <SEP> 190 <SEP> nnn
<tb> fi <SEP> = <SEP> 300mm <SEP> a <SEP> - = <SEP> 27 <SEP> Mm
<tb> f2 <SEP> = <SEP> 220 <SEP> mm <SEP> e <SEP> = <SEP> 73 <SEP> mm
<tb>
This example corresponds to the case that you have a collimated film and a taking lens
