Abstract

For over 40 years, NRaD (formerly NOSC) has been involved in radiometric testing and evaluation of long wave infrared optical filters and materials for a great number of military and civilian programs. Over this time, NRaD's cryogenic filter and materials measurement capabilities have evolved to include spectral emittance from 2.5 to 25 microns and spectral transmittance from 1.5 to 50 microns with spectral attenuation measurements to 10^-7. Recent upgrades allow continuous sample temperature control from 4.2 to 300 Kelvins for all emittance and transmittance testing. In addition to radiometric testing, NRaD routinely conducts space environment dose simulation testing on LWIR optical components under sensor operating conditions. Accumulated dose levels from 0.001 to 1 megarad (Si) are easily achieved. Results of recent emittance, transmittance and low level dose testing are included. Measurement theory and data limitations are also discussed.
