News & Applications

  • Free PSM data logging software available

    A user of a PSM mentioned that it was too bad that data of spot positions could not be logged in the PSM Align software. This is true, data cannot be logged in the PSM Align software, but there is a version of the software designed for use with the centering station, LCS-PSM Align, that does log data. We do not send this version of the software out with the PSM alone because we figure it is not needed, at least initially, and it just adds more to the time to get familiar with the PSM.

    On the other hand...

  • 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.

KEEPING UP WITH THE MANY USES AND APPLICATIONS OF THE PSM

It is difficult to keep up with the many uses and applications of the PSM, so we have put together a list of papers of journal articles sorted by application where others describe how they have used the PSM in their work. In each case we cite the article so you can find the whole paper. We also highlight the specific reference to the PSM in the paper. Here you will find applications that come closest to your interests from researchers around the world.

Case Studies & Testimonials

  • Sometimes good news goes unnoticed for the longest time. We just stumbled on this unattributed, but complimentary note about the PSM.
    See  https://www.idex-hs.com/wp-content/uploads/2018/05/Enabling-Micron-Level-Mounting-Accuracy.pdf   

    Notice the PSM in the top center of Fig. 9.  Optical Perspectives Group would like to express "thank you, IDEX".

  • "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!!"

    Dr. Shaojie Chen

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