About our company. PEGASUS OPTICS, owned and operated by John Hall, has been in business for over 15 years and has an international reputation for quality and optical performance. John personally configures all PEGASUS OPTICS mirrors to a stringent tolerance using professional equipment and techniques for telescope optics from 12.5" to 25" diameter in 1.6" through 2.0" thickness. John is committed to customer service and to crafting individual mirrors that deliver superb optical performance.

Production capacity. In a given calendar year, PEGASUS OPTICS limits production to no more than 30 mirrors. When orders accumulate to exceed this number, we stop accepting further orders. For this reason, please contact us for availability, as demand and delivery times can vary throughout the year. If our order backlog exceeds production capacity, we may find it necessary to temporarily defer further orders until we have a satisfactory capability to meet customer delivery expectations.

Description of mirrors. Our primary mirrors are 1.6" thick in sizes up to 18", and 2" thick 20" and larger diameter. Mirrors are fine or precision-annealed and fine ground on the back surface. Thickness and diametral tolerance is .125". Standard focal length is as shown on the price list +/-1.5%. Coatings are >95% reflectance and include SiO2 (Quartz) overcoat.

Each mirror is etched with owner name, serial number, and optician signature. Traceability, quality data and certification package corresponding to the serial number is maintained in an historical file.
