Only the best telescope optics!

Fabrication of world-class optics is only possible with accurate feedback via high-quality testing. To this end, ASA has invested in the finest test equipment available! Our optical system utilizes a precision iterative process to remove measurable errors – allowing us to achieve the highest quality optical figures available.

With glass blanks in stock, we can produce up to 2.5-meter optics in less than 3 months from order to delivery!
Lenses can be made from any material available in Schott’s glass catalog or CDGM.
We welcome your inquiries.“

ASA 800mm f2.5 mirrors

are produced at our optical facility using high-quality Computer-Generated Holograms made possible with a specially designed measurement tower, and our vibration-immune interferometer.

We are currently running a serial production with an output of one mirror every 3 weeks.

Outstanding optical performance!

This 1000mm f1.8 mirror was produced using a multi-axis CNC-controlled processing center in conjunction with our high-quality testing process. The final mirror figures were ~2x better than specified by the customer.

• Pixel sampling was 1.67 µm
• Wavefront RMS is 23 nm
• PV is 113 nm

Our customers benefit

from our expanded optical capabilities

The optics we produce today are vastly superior to the optics that we can purchase!

Our CNC based state-of-the-art polishing techniques allow us to accurately remove surface errors like astigmatism in the continued quest for optical perfection. In addition, we are able to produce any free form surfaces such as an off-axis parabola and even more complicated shapes.

We specialize in

aspherical optics in sizes > 300mm for

  • Astronomical telescopes
  • Lidar System
  • Laser Communication Telescopes
  • Wide Field Telescopes for Space Surveillance
  • Off-Axis mirrors (Laser Beam Focusing, Spectroscopy, Beam Expanders)
  • Collimators
  • On-Axis Parabolic mirrors (convex and concave)
  • On-Axis Hyperbolic mirrors (convex and concave)
  • Ellipsoids
  • Flats

ASA testing tower

a specially designed building

This measurement tower uses a vibration-immune interferometer to produce high-quality computer-generated holograms. These measurements are fed into state-of-the-art CNC-based polishing robots, which precisely remove surface errors like astigmatism in the continuous pursuit of optical perfection. This allows ASA to produce nearly any freeform surface, such as off-axis parabolas and even more complex shapes.

Fabricating world-class optics is only possible with accurate feedback from high-quality testing, which is why ASA has invested in top-tier test equipment and optical robots. Their optical processes employ a precision iterative method to eliminate measurable errors, enabling them to achieve the highest quality optical figures available.
