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...

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.

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.

Robert (Bob) Parks presented two newly published papers. 

The MicroFinish Topographer helped bring you this spectacular image of the sun.

A combination of the Auto Gain function of the Point Source Microscope (PSM) and the use of an Axicon grating make centering of severely misaligned lenses easy.

Recently a customer was using the Point Source Microscope (PSM) to align a slow, singlet objective lens and find its focus. 

The Optical Society offered Robert (Bob) Parks an opportunity to share his stories of excitement and inspiration in a couple of short videos.

For the last three years Optical Perspectives Group, LLC (OPG) had a licensing agreement with Trioptics-USA to manufacture and sell OPG products exclusively world-wide.

Using the CaliBall^TM to calibrate interferometer transmission or reference spheres using the random ball test is almost fool proof.

However, observing a few simple precautions will improve the results of the calibration.
