Two New Papers to be presented with 2020 (VIRTUAL) SPIE Conference
During the SPIE Optics + Photonics Free Digital Forum
Measuring the radius of curvature of a spherical surface
This month's PSM application describes measuring the radius of curvature of a spherical surface.
Report on finding best focus of slow systems
Experimental setup:
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.
PSM mounting hardware
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?
Can the PSM find best focus of an f/25 optical system to less than ± 10 μm?

Rapid centering small lenses using an Axicon grating and the PSM
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.
How the PSM caught a potential problem
Recently a customer was using the Point Source Microscope (PSM) to align a slow, singlet objective lens and find its focus.

Videos from The Optical Society
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.
News announcement about what is happening in 2018 for OPG
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.
NEW Instructions for Using CaliBall
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.
Webinar: The Autostigmatic Microscope and Its Uses
This webinar with Robert Parks is presented by the OSA Systems and Instrumentation Technical Group.
MFT MicroFinish Topographer Mentioned In Five Papers Given at Telescope Conference
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.
Why is optical alignment so important to optical system performance?
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?
