Portable Reflectometers for Rapid Absorptance & Emittance Measurements

The Surface Optics coatings lab is a preferred supplier to the space industry and is ready to assist your mission with:

Hemispheric Directional Reflectance

Measurements of HDR from 0.3 μm to 50 μm. Typical HDR measurements are made out to 25 μm. Measures the fraction of the light incident on a sample at a given angle that is reflected back into the hemisphere. We measure HDR as a function of incident elevation, polarization, wavelength, temperature, and provide both the specular and diffuse components.

Emissivity

From reflectance measurements (and transmittance where necessary), we generate emittance data as a function of polarization, wavelength, angle, and temperature. Directional, near-normal emittance, when reflectance has been measured at near normal incidence. Directional angular emittance, when reflectance has been measured at any incidence angle other than near-normal.
Total hemispherical and spectral hemispherical emittance, when reflectance has been measured over a sufficiently wide range of incidence angles to permit integration over the hemisphere.
