    we do offer Shack-Hartmann wavefront sensor software package - sales@dmphotonics.com
    Specifications:
    Output:
    • Raw Hartmann images
    • Spot shift map
    • Wavefront aberration map (3D plot, 2D projection, synthesized interferogram, up to 66 Zernike polynomials)
    • Measurement error map
    • PSF (point spread function)
    • MTF (modulation transfer function)
    • Strehl ratio, M2 factor, Gauss-Hermite modes
    • Turbulence parameter estimation (for free space measurements)
    Statistical analysis can be carried out during post-processing. If the system is equipped with a wavefront corrector, our Shack-Hartmann wavefront sensor software allows calculating control signals for the corrector in the closed-loop mode.
    The program package is distributed as a self-installing executable file and/or a C++ SDK, which grants access to all functionality of the sensor and allows complete customization useful to the user’s software.
    The optional program module “M2-sensor” is intended both for measurements of intensity and phase profiles and for estimation of the M2 factor of a single-mode laser beam on the basis of the wavefront measurement data. M2 calculations are carried on according to ISO 11146-2 standard. The module also permits expansion of the multimode beam into Gauss-Hermite modes in both automatic and manual regimes.
    The optional program module “Beam propagation” is intended for simulation of the beam propagation starting from the wavefront sensor input plane to the plane located at a doubled distance to the plane of the beam waist.

    Adaptive optics - deformable bimorph mirrors and wavefront sensors

    Wavefront Sensors: ShaH Family
    A family of ShaH wavefront sensors represents recent progress of Del Mar Photonics in Shack-Hartmann-based technology. The performance of Shack-Hartmann sensors greatly depends on the quality of the lenslet arrays used. Del Mar Photonics. developed a proprietary process of lenslet manufacturing, ensuring excellent quality of refractive lenslet arrays. The arrays can be AR coated on both sides without interfering with the micro-lens surface accuracy. Another advantage of the ShaH wavefront sensors is a highly optimized processing code. This makes possible real-time processing of the sensor data at the rate exceeding 1000 frames per second with a common PC. Due to utilizing low-level programming of the video GPU, it is possible to output the wavefront data with a resolution up to 512x512 pixels at a 500+ Hz frame rate. This mode is favorable for controlling modern LCOS wavefront correctors.
    The family of ShaH wavefront sensors includes several prototype models, starting from low-cost ShaH-0620 suitable for teaching laboratory to a high-end high-speed model, ShaH-03500. The latter utilizes a back-illuminated EM-gain CCD sensor with cooling down to -100°C. This makes it possible to apply such a wavefront sensor in astronomy, remote sensing, etc.

    I am researching adaptive optics systems for a proposal. The only kicker is that we’d like to do everything at NIR for wavelengths near 1500 nm, which is beyond the sensitivity of silicon.
    On the brochure, (www.dmphotonics.com/ShaH_Del_Mar_photonics_web.pdf) there is the statement that “An interface to a variety of CCD and CMOS sensors allows a wide range of acquisition bands from UV to near IR.” Can it interface with an InGaAs camera? I’ve been talking to a different vendor that offers a phosphor coating on the CCD that allows it to respond to 1490 - 1600 nm wavelengths. Do you off anything like that? If not, perhaps we can figure out an appropriate InGaAs camera - I don’t know if you have one you recommend, or I could look around and suggest one to you.
    So I have it, could you send me pricing for this package:
    a. Part# VC.DMU-38-G-24-MDL-000-HP1,06 Unimorph deformable mirror, 25mm aperture, 24 actuators, +/-6um stroke
    b. Part# VC.PDC-24-1-300-100 Control unit, 24 channels, USB, 100Hz bandwidth
    c. Part# VC.SHAH-6-150-3-20 Wavefront sensor ShaH (Shack-Hartmann), 6mm aperture, 20Hz frame rate.
    d. VC.TL-30-6-1,06 Telescope 5X for wavefront sensor, optimized for 1.06um
    e. VC.CLDLL-V2.14 Closed loop software
    f. Includes installation and 3 days training
