Telescope Mirrors

Telescope Mirrors

At Orion Optics UK we pride ourselves on having some of the finest optical technicians anywhere in the world. The optics we produce are world renowned for being among the best available.

Each optical surface is tested up to 29 times as it passes through its many processes of being turned from a blank piece of glass to a highly accurate figured mirror or lens. Below is our selection of telescope mirrors available to purchase and a brief description of each grade’s qualities.

Standard
Our Standard mirrors are produced from quality low expansion Suprax glass from Schott Germany. 1/4 PV wavefront specification giving excellent images for any choice of subject. Coated with now world famous Hilux high performance coatings as standard. The majority of these primaries we make are bought by amateur telescope makers or just customers who want to upgrade the optics in their imported, usually Chinese branded telescope. These mirrors or any telescope we may supply with these mirrors is not supplied with a full Zygo report.
Professional
Professional Grade Optics primaries are produced from quality low expansion Suprax glass from Schott Germany. 1/6 PV wavefront specification giving excellent images for any choice of subject. Coated with highly reflective Hilux, you are guaranteed much brighter images than most telescopes on the market. These mirrors are exceptional in performance and can be relied upon 100% to give virtually flawless images. Supplied with full Zygo interferometer report.
Research
We measure regularly in their manufacturing process and, Zygo interferometer tests confirm, our Research Grade optics are some of the finest optics available anywhere at any price. Produced from quality low expansion Suprax glass from Schott Germany. 1/8 PV wavefront specification giving excellent images for any choice of subject. Coated with Hilux enhanced optical coatings. These mirrors are virtually unsurpassed in performance and will produce some of the finest images available for either visual, film or CCD work. Supplied with full Zygo interferometer report.
Ultra
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 available 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. We fit these as a matter of course to our CT range of ‘scopes ensuring their performance is even further enhanced with a virtual zero expansion, and flexure, high specification Carbon Fibre tube. Each is Supplied with full Zygo interferometer report.
These primary mirrors are expensive, they are also not recommended for just occasional star gazing. Their incredible accuracies and reflective characteristics lend themselves to the realms of optics we have supplied to
