AZ Technology has been a pioneer in development of optical properties measurement instruments, beginning with the Space Portable Spectroreflectometer (SPSR) designed with NASA for measuring total hemispherical
reflectance as an indication of the effects
of the space environment on materials such
as thermal control coatings, viewing windows, reflectors,
solar power systems, etc. The SPSR was flown aboard the Space Shuttle
and used on the exterior of the Russian Space Station Mir. AZ went on to develop a unique line of highly accurate portable and laboratory portable instruments for measuring
the optical properties of materials; specifically, solar absorption,
emittance, solar reflectance, and transmittance. These can be performed for space applications as well as terrestrial applications such as LEED certification.*
To offer optical properties measurements to customers, we use many in-house instruments AZ has developed and markets; for example, AZ's Spectrafire attached to a Thermo-Nicolet FTIR spectrometer, and AZ's LPSR 200IR. This allows measurement of total spectral reflectance
directly within the wavelength range 2.5um to 40um and calculation of emittance and within the wavelength range 250nm to 2800nm calculation of solar
absorption (ASTM E903), transmittance, or emittance (emittance can be measured in accordance with ASTM E408). Also, the TESA 2000 for some specific situation.
AZ Technology also offers Simulated Space Environment Effects Testing and Physical Characterization of Paints and Coatings.
