OUR OWN MIRRORS

All our telescopes are supplied with our own made optics only. The high quality optics you can appreciate on our scopes, are available for ATMs (amateur telescope makers) or for manufacturers. We produce precision spherical, parabolic, hyperbolic and flat mirrors, using finely annealed Pyrex® 7740 glass (std) or ceramic glass (by request).

All diagonal mirrors are finely annealed Pyrex®7740 made.
We can provide for out of standard sizes, by request.
(*) Interferometric test is not available for these dimensions.
At the moment we don't produce ceramic glass secondary mirrors.

All our primary and secondary mirrors are tested with quantitative systems. Standard correction is lambda/4 on wave front P.V., or lambda/8 on wave front P.V. (by request).

All optics are supplied with interferometric certification.
