Abstract: The present invention is directed to an optical system for measurement of a three dimensional device. The optical system is designed and configured to meet telecentric and f-.theta. requirements. The system employs primary and secondary mirrors operating in conjunction with a tertiary deflector mounted on a pivot. Light from a light source produces a beam which is deflected off the deflector and the secondary and primary reflectors respectively. The beam is then transmitted to the surface of the object to be measured. Deflection of the tertiary deflector on the pivot results in scanning of the light beam across the surface of the object to be measured.

The illuminator system includes a light source which produces a light beam; an optical condenser between the lamp and the film gate to condense and shape the beam; and optics adapted to diffuse and direct the light beam so as to produce a uniform line of controlled diffuse illumination at the film gate. A spherical relay lens between the lamp and the optical condenser has a focal length nominally equal to a distance between the relay lens and the optical condenser to constrain the beam within the entrance pupil of the optical condenser. A spectral filter is between the lamp and the film gated to remove unwanted wavelengths of radiation from the light beam.

Abstract: A mirror recoil preventing device suitable for a camera has a mirror and a mirror support frame. The mirror support frame movably supports the mirror in movement from a first position to a second position. In a camera having a photographic lens and a range finding element, the mirror guides light from the photographic lens to the range finding element when positioned at the second position. As a first alternative, the mirror support frame has a U-shaped groove at one end thereof. A regulating member is located in the vicinity of the second position to engage with the U-shaped groove when the mirror support frame is at the second position. As a second alternative, the mirror support frame has a leading edge and a trailing edge such that in movement from the first position to the second position, the trailing edge trails the leading edge. A first regulating member is located to be immediately adjacent to the leading edge of the mirror support frame when the mirror support frame is at the second position.
