Adaptive Optics Deformable Mirrors Wavefront Sensors

Shack-Hartman wavefront sensors : a very effective technology

Shack-Hartman wavefront sensors are made by placing a lenslet array between a refracting telescope and a digital camera. The image is transferred to a software which is able to analyze the wavefront and to measure its aberration.

Shack-Hartman wavefront sensors are the bestsellers for any wavefront application.

The Highest Sensitivity

Wide Spectral Range

High Speed

Our Shack-Hartman wavefront sensors are equipped with the best digital cameras available on the market, to fit perfectly your application.
By using the proper digital camera and adapted optics, our Shack-Hartman wavefront sensors can cover a wide spectral range.
A Shack-Hartman wavefront sensor equipped with a good camera and good software is able to operate at very high speeds.
