Simulated Space Environment Effects Testing System ( SEETS) with LPSR 300V attached |
Our Ultra-high vacuum chamber allows for insitu tesing and measurement of optical properties within a simulated space environment. (See also our space effects measurement service):
- Equipped with a 1600 Watt SpectraPhysics ultraviolet (UV) light source and a 150 Watt Hamamatsu Deuterium vacuum untraviolet (VUV) light source. The UV source uses a water
filter to minimize sample heating, upgradeable
by adding both low energy Electron Flood Gun and
Proton Sources;
- Insitu measurement of total spectral
hemispherical reflectance and solar
alpha can be made by utilizing AZ Technology's LPSR-300V
insitu spectroreflectometer; (Wavelength
range: 250-2800nm; Measurement time two
minutes per sample);
- Twelve 1"x.75" samples can
be exposed simultaneously;
- Types of samples include:
- powder,
- thin films,
- coatings;
- Temperature controlled -30 C to 100 C
- Sample tray transfer mechanism between
exposure and measurement chambers
utilizes a retractable linear magnetic
translator attachment,
- The sample tray's orientation is
horizontal.
- Vacuum system is UHV and utilizes both
ion and turbo pumps. Operational vacuum level
is ~10-9 Torr and the sample exposure chamber
is ion pumped.
- Insitu monitoring of irradiance utilizes
an insitu fiber optic probe for spectral
radiometer data of the UV source and a
NIST calibrated detector for the VUV source.
*Note: terms reflectance, emittance and absorptance and terms reflectivity, emissivity and absorptivity are often used interchangeably. Spectroreflectometer, spectro-reflectometer and spectral reflectometer are also used interchangeably. |
