  • Need custom optical test equipment?

    Need custom optical test equipment?

    Why start from scratch when you can order a PSM from our website?

    It may surprise you but about 15% of Point Source Microscopes (PSMs) purchased are built into custom optical test hardware. Optical Perspectives supplies a CAD model of the PSM to help the customer integrate the PSM into their test hardware design. When the custom hardware is built the PSM is bolted in place, connected to its computer and the test hardware is ready to use as an autocollimator, alignment device or centering sensor.

  • Using the PSM as an Autocollimator

    The other day I got a call from a PSM user asking about calibration. What he was really asking about was the setting of the zero, or origin, on the video screen.

  • Adding mechanical datums to CGHs and Fresnel mirrors

    In general, computer generated holograms (CGHs) and plane Fresnel mirrors (and lenses), made by the same techniques as CGHs, have optical “datums” or foci that are “rigidly attached” to the CGH or Fresnel plane substrate and move in six degrees of freedom with the substrate.

Case Studies & Testimonials

  • "We are enjoying our Point Source Microscope and finding it invaluable in alignment and diagnostic tasks."

    Dr. John Mitchell
    Senior Optical Metrologist
    Glyndwr Innovations Ltd., St. Asaph, Wales, UK

     

  • "Just wanted to share a recent success aligning an adaptive optics test bed with the PSM. We used to use a traditional alignment telescope in the past, but the PSM made the whole process really easy and fast. The main requirements were to quickly determine the quality of beam collimation and pupil conjugates since there are several beam expanders and compressors with multiple pupil and focal planes."

  • "You are always responsive and give us lots of useful information!!"

  • "As always we are very much loving the instrument, I personally love the camera upgrade from what I'm used to!"
