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.

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.
Featured Products
New Products
Right Angle Adapter Accessory for PSM
The Right Angle Adapter (RAA) is an attachment for the Point Source Microscope (PSM) that adds flexibility to the PSM by allowing the objective to be attached at right angles to the axis of the PSM.
Set of 10 balls for use with the PSM
Precision balls for use with the PSM for alignment and assembly of optical systems.
“C” mount Objective Adapter
The “C” mount has 1”-32 TPI and fits many Edmund Optics lens tubes and fittings.
Thorlabs SM1 Objective Adapter
The Thorlabs SM1 adapter with 1.035-40 TPI fits many Thorlabs SM1 lens tubes.
Mitutoyo Objective Adapter
The Mitutoyo adapter with M26x36 TPI fits their long working distance objectives.
Calibration Package for PSM
OPG offers a NIST traceable square wave grating with 4 lp/mm spacing for use in calibrating the lateral scale of the PSM and other optical instruments.
Calibration Package for PSM Angular Measurement
OPG offers a PTB traceable 1” diameter window with an approximate 30 arc minute wedge measured for exact value to better than 1 arc second on a Trioptics PrismMaster and a Certificate of that measurement.
Optical Perspectives Group, LLC is pleased to announce that Optical Support, Inc. of Tucson, AZ is manufacturing all of our products, including the Point Source Microscope, the MicroFinish Topographer and the Axicon Centering Station. Optical Support is a vertically integrated, engineering services company specializing in design and manufacturing of precision optical instruments and custom metrology tooling.

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. 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."
