About
The 410-DHR measures integrated surface reflectance at two angles of incidence (20 and 60 degrees) across six wavelength bands spanning 0.9-12 micron. It is portable, performs measurements in 10 seconds with touchscreen-guided calibration, and can be used on curved or large targets without special fixtures. Applications include infrared signature management, thermal-camera calibration, low-observable coatings characterization, emissivity measurement, and radiative heat transfer analysis.
