Coming this spring is a very special gift for Imagine Optic’s 25th birthday: the HASO gets a 16-fold phase-point resolution enhancement by combining Shack-Hartmann technology with a phase retrieval algorithm applied at microlens scale.Developed from the designs of our HASO4 Broadband and HASO4 126 VIS, the HASO LIFT 272 and LIFT 680 will perform on par with their counterparts in every aspect, and they will also be able to reach 272 x 200 and 680 x 504 phase-point resolution, respectively.
Applications that will benefit from these new sensors range from complex optical systems to freeforms and metasurfaces, but not only these; the sensors’ versatility means that many optical scientists and engineers will be able to take advantage of their superb accuracy.
The only 400 – 800 nm High-Resolution Alignment-Free Wavefront Sensor
Providing outstanding performance, the HASO wavefront sensor family is used worldwide in the most demanding applications in optical metrology, industrial control, microscopy and laser diagnostics. Developed from the design of HASO4 Broadband, the HASO LIFT 272 high-resolution wavefront sensor is as powerful as its counterpart in terms of accuracy and dynamic range, while offering an unequaled resolution of 272 x 200 phase points. This allows the HASO LIFT 272 to provide high-level of performance for applications requiring high accuracy, high dynamic range and high 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
- 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
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. Developed from the designs of our HASO4 Broadband and HASO4 126 VIS, the HASO LIFT 272 and LIFT 680 will perform on par with their counterparts in every aspect, and they will also be able to reach 272 x 200 and 680 x 504 phase-point resolution, respectively. Applications that will benefit from these new sensors range from complex optical systems to freeforms and metasurfaces, but not only these; the sensors’ versatility means that many optical scientists and engineers will be able to take advantage of their superb accuracy.
The images above were obtained in a characterization set-up and demonstrate the resolution improvement obtained with the LIFT algorithm. A high resolution phase image generated by a Spatial Light Modulator ( SLM ) was relayed to our wavefront sensor. The difference with or without the LIFT algorithm activated is striking. An in-depth study shows a 16 x resolution improvement (4 x resolution improvement in both X and Y directions).
Outstanding Performance Examples with HASO Lift 272
- Beam collimation with an accuracy better than 300m radius of curvature
- A 20mm focal length measurement with a sensitivity of 1µm rms
- Direct wavefront acquisition of converging and diverging F/5 beams with an accuracy of about λ/100 rms including astigmatism and high order aberrations
- Control and adjustment of axial laser beam deviation better than 3µrad rms
- MTF measurement with an accuracy better than 99%
Best for Versatility
- A great choice for lab or industrial application
- Successfully used in the most demanding of applications in optical metrology, microscopy and laser diagnostics.
- Optimize the alignment of complex systems
