G&H OL 345 – Irradiance and radiance standards with diffuser 45W

The OL 345 radiation standard consists of a 45W tungsten lamp in an air-cooled cylindrical casing (L=27cm, D=14cm). Due to the diffuser a calibration with irradiance and with radiance at the exit port of 2.5“ can be realized.

The calibration for spectral radiance can be offered in the range from 350 to 1100nm and for the spectral irradiance from 250 to 2500nm. For the visible spectral range, a calibration of illuminance, correlated colour temperature and colour coordinates is available as well.

The standard is equipped with a support for filters of a size of 2“ x 2“.

The OL 65A can be used as a precision power supply.
