OTS Optical Parameter Measuring Instrument (Focus Meter)

The OTS 200 and OTS 500 optical test stations are systems for measuring all classical optical parameters, such as EFL (positive/negative), BFL, FFL, Radius (concave/convex), MTF on axis, and centration errors of single lenses/optical systems.

The accompanying software offers a wide range of functions for non-contact measurement of the position of the mirror surfaces in complex lens groups, thus determining the air spacing between the lenses, the center thickness of each lens, and the center offset.

High precision, simple operation, automatic measurement and recording are the characteristics of the new generation of optical measuring instruments. The OTS series of equipment meets these requirements excellently, thus opening the door to computer-aided optical manufacturing quality control.
