Optics are the heart and soul of any telescope no matter what electronic extras or accessories you buy with your telescope.

You will see that we offer different grades of optics for customers of our VX range and customers wishing to buy optical sets as a separate product. Our Professional Grade which has a guaranteed wavefront accuracy of 1/6PV wavefront and our Research Grade which is 1/8th PV wavefront. Finally, 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. All these are based on a test wavelength of 632nm generated by our Zygo.

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

We are justly proud that leading Universities and Research Facilities like Atomic Research Laboratories in Abingdon, BAe systems, GCHQ Cheltenham, M.O.D., Zygo Inc. and many more use our optics – these professional bodies will only use Optics of the highest quality and this is what we deliver, not just to professionals but to anyone who wants world class optical components.
