CL2 Halogen Spectral Irradiance Standard (250-3000nm)

  • CL2 spectral irradiance standard reference 250-3000nm

Calibrated in our dedicated laboratory with respect to standards calibrated by the Physicalisch-Technische Bundesanstalt (PTB, Germany), a range of calibration intervals within 250-2500nm is on offer, with a De Vos extrapolation of calibration data provided to 3000nm.

Whilst the CL2 is fitted with a grit-blasted 100W QTH lamp as standard, a range of lamps from 10W to 250W are available. Stable lamp operation may be ensured in operating the lamp with the 610 precision constant current DC power supply. A calibration to obtain CIE illuminant A operation (2856K) can be provided for the calibration of illuminance meters.

A mounting bracket provides a universal interface with all optical tables and mounting systems with the calibration distance measured from a simple datum face to the rear of the lamp.
