Diffuse Reflectance Accessory

June 4, 2009

The DRA-EV-300 is a diffuse reflectance accessory designed for use with the company’s spectrophotometer in material science and general quality control measurements on solid materials. It can be used for inorganic chemistry, solid-state physics, optical materials, plastics, pigments, coatings and nanopowders. The accessory accommodates a useable wavelength range of approximately 220 to 1,100 nanometers. The internal coating of the accessory enables high diffuse reflectance performance across the entire wavelength range.

Pre-aligned optical configuration on a kinematic mount facilitates installation with no alignment. The accessory also has horizontal reflectance sample mounting, holding samples in place with gravity. The gravity mounting lets operators perform multiple measurements on a single spot of a sample without compromising integrity.
