Directional VW Absolute Reflectance Accessory

The VW directional reflection accessory makes it possible to calibrate reflectance standards at near-normal incidence and at oblique incidence for P and S polarization separately, Glan Thompson polarizer included. The total calibration uncertainty which can be obtained on reference mirrors with reflectance more than 80% using this high-performance accessory is typically less than 0.1% in the visible range and less than 0.2% in the UV and NIR ranges.

For use with Lambda L650/750/850/850+/950/1050/1050+ Spectrometers. Must be used with a sphere detector, not included.
