Firebird Optics has achieved a major milestone with NASA Contract # 80NSSC24PB032, showcasing its expertise in developing advanced optical solutions tailored for aerospace applications. Under this contract, Firebird is supplying 300mm UV Fused Silica windows specifically engineered to meet the rigorous demands of NASA's X-Ray and Cryogenic Facility (XRCF) at the Marshall Space Flight Center. These high-precision optics will play a critical role in spectroscopic and cryogenic testing, driving advancements in aerospace technology and supporting NASA's ambitious space exploration goals.

The X-Ray and Cryogenic Facility (XRCF)

The XRCF is the world's largest X-ray telescope calibration facility, combining state-of-the-art technologies for X-ray calibration, cryogenic testing, and contamination-controlled environments. Originally built in 1975 and extensively upgraded over the decades, the facility has been instrumental in preparing instruments for the harsh realities of space. Its contributions include supporting groundbreaking missions such as the Chandra X-Ray Observatory and the James Webb Space Telescope (JWST).

Expanded Capabilities of the XRCF

  • Vacuum Chamber: The facility's massive 20-foot-diameter, 60-foot-long vacuum chamber simulates space-like conditions, achieving ultra-high vacuum levels of less than 10^-6 Torr. This environment ensures that test articles are exposed to conditions mimicking those in deep space.

  • Cryogenic Testing: Operating at temperatures ranging from 15 Kelvin (-414°F) to 300 Kelvin, the XRCF allows precise evaluations of materials and instruments under extreme thermal conditions.

  • Precision Measurement Tools: High-resolution interferometers can detect structural distortions at the nanometer scale, ensuring the accuracy of mirrors and instruments during cryogenic testing.

  • Cleanroom Infrastructure: The facility boasts a 5,400-square-foot Class 2000 cleanroom for preparing test articles and a smaller Class 10000 cleanroom for additional processing, ensuring contamination-free operations.

The XRCF has conducted over 30 cryogenic test operations and numerous X-ray calibrations, ensuring instruments meet NASA’s exacting standards. This includes contributions to NOAA meteorological satellites, the Solar X-Ray Imager, and other critical aerospace instruments. The facility's comprehensive capabilities make it an indispensable asset in NASA’s aerospace development efforts.
