New Product: Low Reflectance Specular Standards

Avian Technologies LLC is pleased to introduce a new low reflectance specular reflectance standard. This standard, which consists of a  2” square of highly polished Schott UG-11 glass backed by a low reflectance diffuse material to absorb any transmitted radiation all encased in a black Delrin holder, will be useful to characterize systems where a standard first surface mirror would be too reflective.

The standard is available calibrated over two spectral ranges (250-2500 nm or 360-830 nm), with the calibration angle at near-normal geometry (8°). The reflectance at this angle is quite flat, in the order of 5-6%R.
