Telescope Mirrors
COMPUTER PARABOLIZED PRIMARY MIRRORS
Making a high-quality telescope mirror is a complex and delicate process that requires highly skilled expertise in optical fabrication.
Our parabolic telescope mirrors are manufactured using a proprietary, precision computer-controlled process, with the entire production workflow monitored by interferometric testing.
The parabolization process is performed by CNC machine, using our unique method.
This approach ensures precise control of the optical figure, resulting in balanced edges, absence of zones, and an exceptionally smooth optical surface. Interferometric analysis confirms wavefront slope errors below 1 arcsecond and transverse aberrations contained within the diffraction disk for the specified focal ratio.
The resulting Strehl ratio is always above 0.95, and typically falls in the 0.97–0.99 range, as documented in our interferometric test results.

PRECISION MIRRORS FOR SPACE AND SCIENTIFIC APPLICATIONS
The same precision that defines our telescope optics extends well beyond amateur astronomy. AstroReflect produces custom parabolic mirrors and optical components for space optics and satellite imaging systems, as well as for universities, research institutes, and scientific programs across Europe and beyond.
Each project is approached as a complete optical system and manufactured to specific dimensional, geometrical, and performance requirements, with every surface verified interferometrically. This individual, project-based approach lets us meet the exacting standards of professional and research applications — from Earth-observation and satellite imaging systems to instrumentation for scientific measurement.
Reflecting Telescopes
ULTRA LIGHTWEIGHT DOBSONIAN TELESCOPE - AR GEMINI
Our “Gemini” astronomical telescopes combine the proven advantages of the classic Dobsonian mount with an optimized, lightweight truss structure designed for easy assembly and transport.
The benefits of an open truss design are well established: reduced weight, high mobility, rapid thermal equilibration of the primary mirror, and compact volume for transportation and storage.
All Gemini telescopes are constructed from high-quality, precision-machined plywood, selected for its mechanical stability and durability.
Every component of the telescope is carefully designed and precisely manufactured to ensure structural rigidity, ease of use, and long-term reliability.
Because the primary mirror is also designed and manufactured in-house by AstroReflect, the optical and mechanical systems are fully integrated, ensuring consistently high optical performance of our telescopes.
Optical Tests
INTERFEROMETRIC TESTS THROUGHOUT THE WHOLE PROCESS
Interferometric testing is the most accurate and objective method for evaluating optical performance.
Each of our telescope mirrors is individually tested interferometrically, providing a comprehensive and quantitative assessment of the optical surface.
Unlike single-profile or zonal tests, interferometry evaluates the entire aperture simultaneously, allowing precise detection of surface errors, zonal structure, and edge behavior.
We also offer interferometric testing as a standalone service, enabling independent verification of mirror quality.
For a limited time, this service is offered free of charge.
