FROM THE OSA PUBLISHING BOOKSHELF OSA Standards Committeeeds. Ronald K. Kimmel and Robert E. Parks We hope you appreciate this republication of ISO 10110 Optics and Optical Instruments—Preparation of Drawings for Optical Elements and Systems: A User’s Guide, first published in 1995. This open-access republication is intended to give you a feel for the ISO 10110 […]

The other day I got a call from a PSM user asking about calibration. What he was really asking about was the setting of the zero, or origin, on the video screen. CROSSHAIRS IN THE CENTER OF THE FIELD  This is the same sort of “calibration” people talk about when using autocollimators, which are the […]

In general, computer generated holograms (CGHs) and plane Fresnel mirrors (and lenses), made by the same techniques as CGHs, have optical “datums” or foci that are “rigidly attached” to the CGH or Fresnel plane substrate and move in six degrees of freedom with the substrate. THIS CONCEPT IS MORE EASILY SEEN BY CONSIDERING A GRATING […]

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. It is easily demonstrated that the PSM lateral […]

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 […]

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 […]
