ABSTRACT:
The position of a diffraction grating in a spectral device is controlled by an arm fixed to a rotatable table supporting the grating. The arm rests against a cam receiving a straight line motion in a direction parallel to the light beam impinging on the grating and passing beyond the rotation axis of the rotatable table.
