Optical Perspectives Group, LLC is pleased to announce that Optical Support, Inc. of Tucson, AZ is manufacturing all of our products, including the Point Source Microscope, the MicroFinish Topographer and the Axicon Centering Station. Optical Support is a vertically integrated, engineering services company specializing in design and manufacturing of precision optical instruments and custom metrology tooling.
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.
Precision balls for use with the PSM for alignment and assembly of optical systems.
The “C” mount has 1”-32 TPI and fits many Edmund Optics lens tubes and fittings.
The Thorlabs SM1 adapter with 1.035-40 TPI fits many Thorlabs SM1 lens tubes.
The Mitutoyo adapter with M26x36 TPI fits their long working distance objectives.
OPG offers a NIST traceable square wave grating with 4 lp/mm spacing for use in calibrating the lateral scale of the PSM and other optical instruments.
OPG offers a PTB traceable 1” diameter window with an approximate 30 arc minute wedge measured for exact value to better than 1 arc second on a Trioptics PrismMaster and a Certificate of that measurement.
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.
How well can the Point Source Microscope (PSM) find a point in space?
I am sorry to say I did not get to meet any of you personally at either the SPIE Optics and Photonics show in San Diego or the American Society for Precision Engineering Exhibit scheduled for Minneapolis in October.

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.
