Calibrated in our dedicated laboratory with respect to standards calibrated by the Physicalish Technische Bundesanstalt (PTB, Germany), a calibration range of 380-780nm is offered.

Fitted with a grit-blasted 250W QTH lamp, stable lamp operation can be ensured by employing the lamp alongside the 610 precision constant current DC power supply. The TSRF standard is fitted with an E27 base and is easily adapted to integrating spheres and calibrated in the pins-up or pins-down orientation.
