Abstract

PURPOSE: To make spectral sensitivity flat and make measurement of high sensitivity possible with simple and inexpensive constitution by disposing a light shielding body having a contour resembling to the spectral sensitivity curve of a photodiode array between a grating and self-scanning type photodiode array.
CONSTITUTION: Light out from a light source 2 is paralleled by a lens 3, passes through a sample cell 4 and is condensed onto an incident slit 5. The incident light is conducted by a mirror 6 to a concave grating 7. The dispersed light is made incident through the window 12 of a light shielding plate A for regulation of the quantity of light to a diode array 1, the output whereof is inputted via a control circuit 9 and a data processor 10 to a recoder 11. The plate A consisting of an opaque plastic, metallic plate or the like is provided with such window 12 of which the contour 12a of the light shielding part assumes resemblance with the spectral sensitivity curve of the photodiode array. Thereby, the spectral sensitivity is made flat with the simple and inexpensive constitution and the measurement of high accuracy is made possible.
