Paper Abstract

Hundreds of luminance telephotometers and microphotometers are in use throughout the world today, but very few of them having scanning microphotometric capability. This paper describes a unique optical system which, without requiring any modification of the photometer's internal optical system, converts an existing photometer into a high resolution scanning microphotometer. The optical system is simply interchanged with the standard objective lens. The system, called the 'MicroScanner Spatial Scanner', will be described in detail. Used with any standard Pritchard Photometer, this scanner provides variable speed scanning of up to 25mms of object space with field coverage as fine as 0.00125 mms. The system features photometric uniformity within ±0.5% over the entire scan distance, freedom from polarization error and a 25mms scan distance.
