A cold light source is external illumination for microscopes or spectroscopes. Due to the greatly reduced infrared content of the light, the sample is hardly heated. This is important for living biological samples that would be killed by the heat of the halogen lighting. In the gemmological field cold light sources are used, because complex shaped objects can be illuminated precisely and without shadows with a twin-arm light conductor. Cold light sources
