CL2_RI Spectral Radiant Intensity Standard (300-3000nm)

  • CL2_RI radiant intensity reference standard 300-3000nm

Calibrated in our dedicated laboratory with respect to standards calibrated by the Physicalish Technische Bundesanstalt (PTB, Germany), a range of calibration intervals within 300-2500nm is on offer, with a De Vos extrapolation of calibration data provided to 3000nm.

Fitted with a grit-blasted 250W QTH lamp, 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 luminous intensity meters.

A mounting bracket provides a universal interface with all optical tables and mounting system.
