G&H OL FEL – High-precision spectral irradiance standard 1000W

The radiation standard OL FEL is a 1000 W FEL lamp with a tungsten coiled-coil filament in quartz glass with a bipolar adjustment plug recommended by NIST. A calibration with a minimum uncertainty of +/-1% or optionally with +/-0.5 can be realized in the wavelength range from 250-2400nm.

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

For the exact adjustment of the radiation standard, the lamp holder OL 61, the adjustable lamp holder mount OL 63 and the alignment jig OL 62 (lamp dummy) are available.

The OL 83A can be used as precision power supply.
