This month's PSM application describes measuring the radius of curvature of a spherical surface.
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.
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 to less than ± 10 μm?
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.
