Applications
Astronomy & Space
Flat optical windows, mirrors and filters for telescopes, observation and space systems, with optical coatings for the visible and infrared bands.
Observation and space systems demand the tightest tolerances on optical surfaces. Because single- and double-side polishing, vacuum coating and interferometric measurement run under one roof, flatness, parallelism and surface quality stay under a single responsibility.
What we supply to this sector
- Optical windows for visible and infrared bands
- Anti-reflective and high-reflective coating designs
- Interferometric surface-form verification
- Opto-mechanical tooling and assembly
Related capabilities
- Single-Side PolishingPrecision single-side polishing of optical surfaces; flatness and surface quality verified by measurement.
- Double-Side PolishingSimultaneous polishing of both faces for optical windows where parallelism and thickness tolerance are critical.
- Optical CoatingThin-film deposition under vacuum; anti-reflective, high-reflective and protective stack designs.
Frequently asked questions
Which optics do you make for space systems?
Flat mirrors, windows and filter substrates up to ⌀ 500 mm, in low-expansion materials including Zerodur and fused silica.
Do the coatings survive vacuum and thermal cycling?
Coatings pass MIL-SPEC environmental tests; thermal cycling and vacuum tests are planned to the specification.
