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.

We hope you appreciate this republication of ISO 10110 Optics and Optical Instruments—Preparation of Drawings for Optical Elements and Systems: A User's Guide, first published in 1995. This open-access republication is intended to give you a feel for the ISO 10110 standard and an overview of its general scope and methodology. It is not intended for use as a standard as it is hopelessly out of date. Copyright 1995
Good news for the New Year, the standard PSM works in the Near IR
Many times potential customers have asked “How far does the PSM work into the infrared?” I told them the standard PSM works as far out as 1050 nm with the CMOS camera that comes with every new PSM because I have used the PSM there with a fiber coupled external source. But some customers want to go farther into the IR.
How well can the Point Source Microscope (PSM) find a point in space?
I am sorry to say I did not get to meet any of you personally at either the SPIE Optics and Photonics show in San Diego or the American Society for Precision Engineering Exhibit scheduled for Minneapolis in October.
During the SPIE Optics + Photonics Free Digital Forum
(Online Only) August 24-28 2020,
Robert (Bob) Parks presented two newly published papers.
This month's PSM application describes measuring the radius of curvature of a spherical surface.
A Point Source Microscope (PSM) was mounted on a motorized vertical stage above a 25 mm diameter, 200 mm efl lens sitting above a plane mirror. A square black paper mask with an 8 mm diameter hole was placed over the lens as shown in the figure below to give an f/25 aperture.
Customers purchasing a PSM often ask me if we offer mounting hardware for the PSM like x-y-z stages.
Can the PSM find best focus of an f/25 optical system to less than ± 10 μm?
