Optical Ground Support Equipment
Optical ground support equipment (OGSE) instrumentation is an extremely accurate equipment. Their goal is to ensure instruments are operating as expected before launch. Thanks to powerful capabilities and ease of use, SID4 wavefront sensors are the perfect wavefront measurement tools for easy integration in OGSE instrumentation.
Optical system alignment
Precise, in situ alignment and collimation of optical systems are made easy with the SID4 wavefront sensor. Live alignment of complex optical systems in the UV, VIS, NIR, SWIR, MWIR, and LWIR is accessible thanks to the large SID4 range. Typical samples under test are space optical components, subassemblies, and assemblies.
Deformable mirror testing
Characterization of deformable mirrors and spatial light modulators for active and adaptive optics is performed with SID4 HR wavefront sensor. The high resolution combined with compactness allow in-situ surface testing and influence-function measurements of deformable mirrors (DFM) with unprecedented accuracy.
Environmental testing
Using the Phasics SID4 V vacuum compatible wavefront sensor with low-outgassing materials, it is now possible to test space optical systems in the environmental chamber. Combined with an R-Cube module, it allows double-pass testing of optical systems and monitoring the wavefront distortions as temperature and pressure are varied.
