Starting in 2020, we'll be featuring an application of the Point Source Microscope (PSM) every month.
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.
