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 high-resolution and LIFT 680 ultra-high resolution wavefront sensors 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 680×504 Phase-Points 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 126 VIS, the HASO LIFT 680 ultra-high resolution wavefront sensor is as powerful as its counterpart in terms of accuracy and dynamic range, while offering an unequaled resolution of 680 x 504 phase points. This allows the HASO LIFT 680 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)
- 342 720 phase point resolution on 13.77 x 10.22 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
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 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).
The Most Advanced Wavefront Measurement and Analysis Software
WaveView4 offers more than 150 features and tools optimized for a wide range of highly demanding applications. Its development philosophy is based on tens of years of customer’s feedback, improving the user experience with each version. Moreover, this software provides a function to analyze segmented wavefronts and allows autosave for sequence measurements. Modules dedicated to PSF, MTF, and M2 are available.
WaveKit is SDK in C/C++, LabVIEW and Python, providing the basic blocks on which one can build a fully customized software for specific HASO-based applications or WaveView4 data processing routines. It is available on request.
Transform your Wavefront Sensor into a full Metrology Solution with R-FLEX & R-FLEX LA
The R-FLEX2 is a versatile optical metrology system that instantly combines any of our HASO4 wavefront sensors in the with a collimator and a light source. R-FLEX2 is currently used for quality control such as life science instrumentation, alignment of large telescopes and collimators, large concave mirrors, and lenses and complex optical systems in general.
The R-FLEX LA is a collimating platform that extends the capabilities of the HASO R-FLEX2 to large optics and optical surfaces. The output collimated beam size ranges from 30 to 150 mm. Analyze large optics such as filters, dichroic beam splitters, head-up displays, eyewear, optical windows, flat mirrors, polarization scramblers.
