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.
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™
Using the CaliBallTM 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.
This webinar with Robert Parks is presented by the OSA Systems and Instrumentation Technical Group.
MFT was mentioned in five of the papers given at the SPIE Conference on Telescopes in Edinburgh, Scotland at the end of June 2016 by authors from six different international research organizations.
The main reason is that the other two major factors in performance, optical design and optical fabrication, have already been improved to the very limits of what can be accomplished. After spending good money on a near perfect design and fabrication of optical components does it make any sense not to assemble them in perfect alignment?
