Right Angle Adapter Accessory for PSM
The Right Angle Adapter (RAA) is an attachment for the Point Source Microscope (PSM) that adds flexibility to the PSM by allowing the objective to be attached at right angles to the axis of the PSM.
Set of 10 balls for use with the PSM
Precision balls for use with the PSM for alignment and assembly of optical systems.
“C” mount Objective Adapter
The “C” mount has 1”-32 TPI and fits many Edmund Optics lens tubes and fittings.
Thorlabs SM1 Objective Adapter
The Thorlabs SM1 adapter with 1.035-40 TPI fits many Thorlabs SM1 lens tubes.

Recently, a client asked how well can you focus if you really had to do better? I did not know but it was easy to do an experiment with our centering station that has a motorized stage and the ability to log data as the stage moves.

I needed to measure the height of a free space fiber termination above an optical bench the other day and in the process remembered a question I had been asked in passing. Since I had the pieces of such an experiment in front of me, all I had to do was save a couple of images.

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.

The PSM is an ideal tool for finding the center of curvature of a ball or the axis of a cylinder. The question is for how small a ball or cylinder can the PSM do this?
The smallest article that was readily available was a piece of monofilament 8 pound test fishing line that was 290 μm in diameter. There was no problem finding the axis of the fishline, and separating the Cat’s eye reflection from the surface from the confocal reflection of the axis. The experiment was done with a 5x objective, and the result would have been even more definitive using a 10x objective.
