Abstract: A wavelength driving device for use in monochromators which comprises an optical element for dispersing light into different wavelengths, means for supporting the optical element for rotation about a first axis, a stepping motor, a first toothed pulley of a relatively small diameter connected to the output shaft of the stepping motor for simultaneous stepwise rotation therewith, a first gear of a relatively large diameter fixed to the supporting means for simultaneous rotation about the first axis, a second gear of a relatively small diameter mounted for rotation about a second axis and meshing with the first gear, a second toothed pulley of a relatively large diameter fixed to the second gear for simultaneous rotation about the second axis, a toothed belt connecting the first and second toothed pulleys, and circuit means for controlling the rotation of the stepping motor.

Abstract: A spectrophotometer including: a) a light source switching mechanism for switching a plurality of light sources by swinging a light source mirror; b) a filter selecting mechanism; c) a diffraction grating rotating mechanism; and d) a controller for determining the operation origins of the three driving mechanisms using a rough origin sensor provided for the diffraction grating rotating mechanism and a photometer. The operation of the controller is to: i) determine an origin of the movement of the filter by making an end of the filter frame to touch a stopper; ii) determine a rough origin of the diffraction grating using the rough origin sensor; and iii) determine an origin of the movement of the light source mirror and a precise origin of the movement of the diffraction grating by detecting the position at which the photometer detects the maximum intensity of light.
