System to augment magnification of optical microscope - has sets of plane convex and concave mirrors reflecting UV light to electronic receiver

The optical microscope develops a real image which is electronically surveyed and amplified. The product of the modulation functions of the optical and electrical amplifications is held as a constant function of the band frequency of the image former. The optical system uses ultra-violet light. The object field may be light, dark, phase-contrast, interference contrast or fluorescent. In the optical system incident light is reflected by a 45 deg. angle mirror (20) to a convex reflector (21) and a pair of concave reflectors (22) through the object (1) and thence through aperture stops (25) and a similar set of mirrors (26, 27) to the pick-up device.
