Parabolic Astronomical Telescope Mirrors 1/12 Wave are polished and figured to yield high-level performance. Each mirror is aluminized and hard overcoated with a protective overcoat, ready for placement in the telescope tube. All mirror surfaces are free of any defects which affect performances. Special types of equipment and techniques make the system mirror the least expensive to any other comparable coated mirror. Resolving power and reflective ability is the specialty of the GSO ASTRONOMICAL TELESCOPE MIRROR QUALITY.

GSO offers very HIGH-quality parabolic telescope mirrors for the people who want to build their telescopes or DIY project. 

Our parabolic telescope mirror size ranges from 6" to 16", all of these mirrors are made from BK7 quality optical glass and all the mirror surface quality over 1/16 wave RMS at the least, typically better.

All telescope mirrors have an aluminum reflective coating, reflectivity is approximately 93%. The aluminum coating is protected by a properly applied protective coating (SiO2).

Secondary flat mirror 1/12 wave (DIAGONAL) are optically flat yield optimum performances when combined with above astronomical mirrors. Each mirror is aluminized and overcoated.

GSO offers secondary flat telescope mirrors to match the complete telescope set request. Our elliptic flat mirror has the same high optical quality as our parabolic primary mirrors using BK7 quality glass. All of the mirror surface quality over 1/12 wave RMS at the least, typically better.

All mirrors have an aluminum reflective coating of 93%. The aluminum coating is protected by a quartz overcoated to make the layer durable against aging effects
