Standard source in CL2

The CL2_RI quartz tungsten halogen (QTH) radiant spectral intensity reference standard is used for the accurate and traceable calibration of teleptroradiometers and light intensity indicators.

Calibrated in our dedicated laboratory according to the standards calibrated by the German Technical Bureau (PTB, Germany), a range of calibration intervals between 300 and 2500 nm is proposed, with an extrapolation from your calibration data at 3000 nm.

Equipped with QTH 250W sandblasted quartz tungsten halogen lamp, stable operation of the lamp can be ensured by using the lamp with 610 precision constant current dc power supply. A calibration to obtain a CIE illuminant One operation (2856K) can be provided for the calibration of light intensity meters.

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