Optical Test Instruments: OptiSpheric® and Spherometer

TRIOPTICS' OptiSpheric® and Spherometer are the classic optical test systems for spherical lenses that can be found in virtually any optical manufacturing process.

 While the Spherometer is used for the tactile determination of lens radii, OptiSpheric® systems provide contactless measurement of effective focal length, back focal length, flange focal length, MTF on axis and the radius of lenses. Specific upgrades allow determining centration errors and angles on plane surfaces.

Systems for testing IOLs in compliance with EN/ISO 11979 form a class of their own. OptiSpheric® IOL is preferably used for measuring single lenses while OptiSpheric® IOL PRO 2 is designed for the fully automated IOL measurement in serial production.
