Imagine Optic HASO4 FIRST Wavefront Sensor

The HASO Shack-Hartmann Wavefront Sensor is optimised for one wavelength, the one you really need. The HASO FIRST is now faster and has an improved spatial resolution while keeping the same accuracy and optimised price point.

Key Features:

• Beam collimation with accuracy of better than 200 m radius of curvature

• 20mm focal length measurement with sensitivity of 1 µm RMS

• Direct wavefront acquisition of converging and diverging F/5 beams with λ/100 accuracy, including astigmatism and high-order aberrations

• Control and adjustment of axial laser beam deviation better than 5 µrad rms

• +/- 50 nm calibration bandwidth or extended wavelength range, optional: +/- 150nm around the calibration wavelength

Applications:

• Quantify the aberrations of an optical system

• Align optical systems to ensure that it works optimally

• Predict the performance of optical systems in terms of focusing capability or imaging quality

• Quantify the effects of temperature and gravity on performance

• Verify that the optics comply with specifications

• Drive a wavefront corrector to correct for system aberrations

• Check whether the optical mount overly distorts the optics
