PublicationsThe Only 400-800 nm High Resolution Wavefront Sensor
The HASO gets a 16-fold improvement in phase-point resolution by integrating Shack-Hartmann technology with a microlens-scale phase retrieval algorithm. Delivering exceptional performance, the HASO wavefront sensor family finds widespread application across the globe in challenging fields such as optical metrology, industrial control, microscopy, and laser diagnostics. Derived from the HASO 4 Broadband and HASO4 126 VIS design, the HASO LIFT high resolution wavefront sensors match their counterparts in accuracy and dynamic range while boasting an unparalleled resolution of 272 x 200 (LIFT 272) or 680 x 504 (LIFT 680) phase points. This unique capability enables the HASO LIFT to excel in applications from intricate optical systems to freeforms and metasurfaces that demand high accuracy, extensive dynamic range, and superior spatial resolution.
- λ/100 rms absolute accuracy on a huge dynamic range (see the graph below)
- 54 400 phase point resolution on 7.0 x 5.2 mm2 (LIFT 272) or 342 720 phase point resolution on 13.77 x 10.22 mm2 (LIFT 680)
- Measurement up to 64 Zernike polynomials with individual accuracy better than 1 nm RMS
- Spot Tracker provides easy HASO alignment and the capability to precisely follow absolute tilt/wavefront evolution over time
Best for Challenging Applications
- High spatial sampling frequency
- Very large dynamic range
- Freeform optics characterization
- Parabolic mirrors characterization
- High spatial frequency aberrations
16x Resolution Improvement with LIFT Algorithm
The HASO gets a 16-fold phase-point resolution enhancement by combining Shack-Hartmann technology with a phase retrieval algorithm applied at microlens scale.
The presented images were captured within a characterization set-up, illustrating the enhanced resolution achieved through the implementation of the LIFT algorithm. A high-resolution phase image, produced by a Spatial Light Modulator (SLM), was transmitted to our wavefront sensor. The contrast between the results with and without the activation of the LIFT algorithm is remarkable. An in-depth study reveals a 16-fold increase in resolution, translating to a fourfold improvement in both the X and Y directions.
