SOC-410 DHR Reflectometer

Infrared reflectance measurements

The 410-DHR is a product of collaboration between U.S. Naval Air Systems Command and Surface Optics, with vital input from the Naval Research Lab (NRL) and National Institute of Standards and Technology (NIST). It was developed to answer a broad need for a portable device for the verification of the optical properties of large objects in the field. The 410-DHR measures the integrated surface reflectance of a surface at two angles of incidence (20° and 60°) and for six discreet wavelength bands in the .9 to 12 μm spectral range.
