Abstract

1362227 Reflex cameras POLAROID CORP 15 Dec 1971 [15 Dec 1970] 58325/71 Heading G2J In a Polaroid reflex camera the viewing image at 100, Fig. 2, is erect and without lateral reversal. To achieve this the image from the lens 14 is reflected from an inclined mirror 30 on to a horizontal mirror 60 and from there to the top of the mirror 30 for transmission via a stop 72 in an aperture 66 to an ellipsoidal mirror 70. The stop 72 is at a focus point of the mirror 70.
