Spectral radiometer or optical instrument calibration device comprises a light source and displaceable mirror that can be used for deflecting a collimated calibration light beam onto the optical instrument

摘要

Device for calibrating an optical instrument with a photoelectric detector. Said device comprises an illumination unit for radiating collimated radiation with a positioning device for adjusting the observation angle of the incident radiation. The positioning device (7) has a mirror (6) aligned with calibration radiation. The mirror can be rotated and translated in a defined manner, so that calibration radiation can be directed onto the optical instrument (11) from a range of angles.
