| Features |
|
- Wavefront sensor with 2 in-built calibration units (one fixed and one motorized), allowing test in parallel light and test with pinhole at focus of the optical system under test
- Uncooled camera, IR camera or UV camera can be mounted according to the requirements for wavefront analysis
- All the optical elements are mounted along the optical axis
- The optical system under is mounted on a motorized table on an auxiliary x-y table, to allow a precise centering with respect to the optical axis
- Standard sampling: 30 x 30 spots with uncooled camera
- Maximum
sampling:
100 x 100
spots
- For testing aspherical lenses up to 20mm diameter and digital cameras
- Φmax=20mm (with test in parallel light)

| Software |
|
- Automatic optimization of the SH image
- The software checks that the optical parameters required for the analysis are correct
- On-line calibration using the 2 in-built calibration units
- On-line alignment of reference and test image
- On-line collimation (manual and automatic)
- Automatic optimization of exposure-time
- Wavefront reconstruction (any user-selected aberration removed)
- 70 Zernike aberration terms
- 3 types of Zernike (Standard, Fringe, Annular) and Seidel polynomials can be fit to the data
- Average of images, coefficients and wavefront to reduce noise
- Automatic computation of optical quality for three cases:
(i) tilt or tilt & defocus removed;
(ii) 7 Zernike terms removed;
(iii) user-selected Zernike aberrations removed
- Analysis in real-time (2D and 3D
wavefront, Zernike aberrations, spot diagram, residuals)
- On-line optical alignment of complex optical systems
- On-line adjustment of spacing between optical elements
- MTF, PSF, EE (optional)
- Over 50 graphs to help you interpret the results
- Output in Text as well as Excel format
- Creation of test report
