Alcor System

Shack-Hartmann 40 x 40

Notify me when this product is available:

This product is intended to measure accurately optical wavefront (> ?/55) coming from telescopes, refractors or any optical setup.

Or said more simply, it measures the optical performance of optical systems, based on Shack-hartmann wavefront analysis.

The product comes with a 5 megapixel camera and microlenses array, a visual aiming system and a set of collimators to acommodate with F/ number from F/3 to F/20. The next picture shows the uncooled version of the Shack-Hartmann. 

A cooled version of the camera sensor that performs the analysis is proposed, allowing long exposures (say, 2 to 5 minutes). Instead of an eyepiece, a sighting camera can be installed (camera on top) for both systems (cooled & uncooled).
