Airy Disk makes ED and APO telescopes, lenses, spherical and aspherical
mirrors with diameters ranging from 45mm to 400mm.
Our production process is highly integrated.
From lens and optical system design, nearly all steps of the telescope
making process are now in-house:
- Blank Preparation, Lens Grinding, Polishing and Centering
- Coating
- Quality Control
- Lens mounting
- Final assembly and inspection, collimation and interferometric testing
Packaging
The glass used comes from CDGM and Hoya.
Lens mounts are made by the inhouse CNC department as are most of
the telescope components.
State of the art testing equipment, a huge collection of spherical
masters, Fizeau interferometer in red(632.8nm), TwymSan green in
green spectrum(532nm), artificial star and Ronchi.
This control over the whole manufacturing process combined with our
skills and experience results in outstanding optics.
Decades of specialized ED production using Ohara FPL53. Over the
years, the company has provided optical system design, production,
and OEM production for many well-known brands in China.
