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.
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.
OSA Stories
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™
However, observing a few simple precautions will improve the results of the calibration.
This webinar with Robert Parks is presented by the OSA Systems and Instrumentation Technical Group.

The PSM is an ideal tool for finding the center of curvature of a ball or the axis of a cylinder. The question is for how small a ball or cylinder can the PSM do this?
The smallest article that was readily available was a piece of monofilament 8 pound test fishing line that was 290 μm in diameter. There was no problem finding the axis of the fishline, and separating the Cat’s eye reflection from the surface from the confocal reflection of the axis. The experiment was done with a 5x objective, and the result would have been even more definitive using a 10x objective.
