G&H OL 200, 220, 245 – Spectral irradiance standard 1000W, 200W, 45W

The radiation standards are tungsten coiled-coil lamps with lamp caps at both sides in small quartz glass envelope. The spectral calibration is available with an uncertainty of 1- 2% at NIST wavelengths of 250nm-2500nm for the 200W- and 1000W radiators up to 4500nm. Optionally, an uncertainty of +/-0.5% can be supplied.

For the visible spectral range, a calibration of illuminance, correlated colour temperature and colour co-ordinates is available as well.

To precisely adjust the radiation standards the two-sided lamp holder OL 56 (for OL 200) and OL 57 (for OL 245) and OL 57W (for OL 220) and the adjustable lamp holder mount OL 63 are available.

The OL 65A (for OL 220 and OL 245) and OL 83A (for OL 200) can be used as precision power supply.
