Simulated Space Environment Effects Testing:

LPSR 300 V Attached to AZ's Custom Designed Ultra-high Vacuum Chamber allows for insitu optical properties testing and measurement within a simulated space environment

To complement our optical properties measurement and physical testing of paints and coatings, we can also offer customers in-house Space Environment Effects testing of coatings and thin films and materials using our custom designed ultra-high vacuum chamber (ion pumped). This simuated space enviroment facility is equiped with solar ultraviolet and vacuum ultraviolet sources, 12 sample capacity with a temperature controlled sample tray, air-lock access, and in-situ optical measurements (total spectral hemispherical reflectance from 250-2800 nm and solar absoption) using the AZ Technology instrument LSPR 300V. Non-coating materials can be tested, but there are size limitations. The coatings are typically applied to 0.5" by 1" custom designed coupons that fit into a 6" diameter plate. Reasonably thin materials can be cut to size and adhered to these coupons using Y966 low out-gassing adhesive. The system is upgradeable by adding both a low energy Electron Flood Gun and Proton Sources.

*Note: terms reflectance, emittance and absorptance and terms reflectivity, emissivity and absorptivity are often used interchangeably.
