摘要

Spectral analyser and colorimeter photo-receiver has several light sensitive receivers with differing spectral sensitivities. The light sensitive sides of the receivers are covered iwth a filter and one or more corresponding, location independent, block filters. The spectral transmission rate of the filter is a continuous location dependent quantity. One surface (2) of the photoelectronic receiver (1) has a wind out. The light sensitive sides of the photoelements, photodiodes (3) or phototransistors are vapour deposited or bonded on the bottom of the wind out which may contain a double row of ten diodes.
