With our continuous developments in optics we have now reached a position where we can offer with 100% reliability, optics which we believe are the best availabe anywhere in the world. Our Ultra range has Strehl values typically around 99% with RMS values of the order of 0.02PV. Coupled with a guaranteed PV wavefront error so small, it often is less than 1/10PV wavefront.
These optics are expensive, they are also not recommended for just occassional star gazing. Their incredible accuracies and reflective characteristics lend themselves to the realms of optics we have supplied to:
BAe Systems
Zygo Inc.
M.O.D.
Atomic Energy Nuclear Fusion Research Laboratories, Culham
GCHQ Cheltenham
etc., etc.
Each is Supplied with full Zygo interferometer report
