SPG’s spectral measurement capabilities include testing spectral ranges from 0.190 microns to 50 microns. Reflectance and transmittance tests range from near normal to 45 degrees and cryogenic measurements can be characterized from ambient to < 10 Kelvin. Polarized measurements (S&P) are also available, if needed, and hemispherical transmittance and reflectance tests measure from 0.190 microns to 2.5 microns.
Environmental testing is performed to MIL-C-48497 and MIL-F-48616 standards. DSI’s Special Products Group can perform tests for humidity, salt fog, abrasion, temperature cycle, adhesion, solubility and cleanability. Physical test and measurements available include flatness/reflected wavefront error, surface quality characterization (e.g. scratch/dig, scatter, etc.), surface resistivity, and dimensional verification.
