Cost-Effective Diffuse Reflectance Accessory

Thermo Fisher Scientific, Inc recently announced a new Thermo Scientific Diffuse Reflectance Accessory, specially designed to complement the powerful Evolution™ 300 UV-Visible spectrophotometer. The DRA-EV-300 is a cost-effective solution for material science and general QC measurements on solid materials. At half the price of some competitive systems the new accessory is affordable for a wide range of applications including inorganic chemistry, solid state physics, optical materials, plastics, pigments, coatings and nano powders.

The Thermo Scientific DRA-EV-300 Diffuse Reflectance Accessory accommodates a useable wavelength range of approximately 220 to approximately 1100 nm. In competitive instruments the extended wavelength range is only 900 to 1100 nm. The internal coating of the DRA-EV-300 consists of a sintered PTFE material that enables excellent diffuse reflectance performance across the entire wavelength range. Pre-aligned optical configuration on a kinematic mount facilitates simple and convenient installation with no alignment. The DRA-EV-300 also features horizontal reflectance sample mounting, safely holding samples in place with gravity. Other systems require spring mounted clips to hold a vertical sample in place which can often damage delicate surfaces. The gravity mounting lets scientists easily perform multiple measurements on a single spot of a sample without compromising integrity. The DRA-EV-300 is designed to complement the Evolution 300, a high-performance, double-beam UV-Visible spectrophotometer, which incorporates a high intensity and long life Xe flash lamp. The instrument achieves fast, reliable and flexible scanning, fixed wavelength analysis and a variety of other measurements including colour calculations and various materials calculations.
