SRS12 Halogen Spectral Radiance Standard (250-2500nm)

  • SRS12 12" sphere QTH spectral radiance reference standard
  • SRS12 twelve inch sphere spectral radiance standard connectors

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

The 300mm diameter SRS12 features a BaSO4 coated integrating sphere complete with baffled, grit-blasted 100W QTH lamp and 100mm diameter window to deliver exceptional radiance uniformity. Stable lamp operation is ensured in employing the lamp with the 610 precision constant current DC power supply.
