Continuing in 2021, we feature an Application of the Point Source Microscope (PSM) every month or so.
Adding mechanical datums to CGHs and Fresnel mirrors
How repeatably can the Point Source Microscope find best focus at a center of curvature?
How well can the Point Source Microscope (PSM) locate the source of a single mode fiber?
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
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.
