Wavefront-based inspection of astronomical telescopes

Astronomical telescopes and astrographs have to deliver sharp images in extremely low light for observing celestial bodies. Consequently, the demands on design and production are particularly high. Shack-Hartmann wavefront sensors are already used in the manufacture of the individual telescopic elements, e.g. for functional testing.

Simplified alignment, highest precision

The particular strength of Optocraft’s systems becomes apparent during the alignmentment of astrographs or telescopes, because they simplify this process considerably. Due to the wide dynamic range, a wavefront measurement can already be carried out, even if the initial state of the telescope is severely misaligned. Further adjustment steps can then be derived from this.

With fine adjustment, users of wavefront measurement technology benefit significantly from the outstanding basic accuracy and intrinsic stability of the process. Even the slightest misalignment is reliably detected, and can be corrected easily.

Our solution for the inspection of astronomical telescopes

SHSLab wavefront sensors and the modules of the SHSInspect family measure the transmitted wavefront at wavelengths from 193nm to 1700nm and provide a Zernike analysis and the associated PSF/MTF.
The Shack-Hartmann software SHSWorks offers both a flexible user interface/GUI and an SDK for integration in customer applications.
Many years of experience in the implementation of customer-specific systems make Optocraft the go-to partner even for the most demanding applications!
