Wavefront Testing Under Thermal & Vacuum Conditions

Still the best optical metrology tool even under harsh conditions

Cutting edge aerospace and defense optics need to be tested in field conditions. This may include turbulence, vibration, cryogenic freezing, vacuum conditions, and more. Phasics' patented QWLSI technology is, by design, very compact and not sensitive to vibrations. Adding years of specific development to this, Phasics proposes devices that meet demanding performances in harsh environments.

• ▽ In-situ wavefront qualification during TVAC testing

  

  The Phasics SID4 V is the only high-resolution vacuum-compatible wavefront sensor capable of performing wavefront measurements directly inside the vacuum chamber. Combined with an R-Cube illumination module, our wavefront sensors are perfect for in situ qualification of space systems in double or single-pass configuration.

  A similar setup can be achieved by placing the optical test instruments outside of the vacuum chamber.
