Thermo Fisher Scientific Introduces Cost-Effective Diffuse Reflectance Accessory Enabling Rapid, Accurate Measurements for Material Science Applications

(Nanowerk News) Thermo Fisher Scientific Inc. has 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. Further information on the DRA-EV-300 is available at
The Thermo Scientific DRA-EV-300 Diffuse Reflectance Accessory accommodates a useable wavelength range of approximately 220 to approximately 1100 nm. In competitive instruments, as much as three times more expensive, 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 color calculations and various materials calculations.
