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.
In-band reflectance & emittance
.9 – 1.1, 1.9 – 2.4, 3.0 – 4.0, 3.0 – 5.0, 4.0 – 5.0, 8.0 – 12.0.
Curved and large targets
Measurements can be taken without special jigs or fixtures.
Dual angles of incidence
Near normal 20° and near grazing 60° incident angles.
Easy to use
Simply press port against sample and pull trigger.
Fast data collection
10 seconds or less per measurement
Grazing angle option
80° incident angle configuration option
