Optical Test Instruments
OptiSpheric® & Spherometer - Trioptics GmbH
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 R&D is preferably used for measuring single lenses while OptiSpheric® IOL PRO 2 is designed for the fully automated IOL measurement in serial production.

Intraocular Lens Optical Test System
OptiSpheric® IOL R&D
The OptiSpheric® IOL R&D is specially designed for the analysis of single intraocular lenses in research and development. With the OptiSpheric® IOL R&D, important parameters of all types of lenses (monofocal, multifocal, trifocal, toric, aspheric and those with extended depth of focus (EDOF) – whether diffractive, refractive or sectors) can be measured and tested in air or in situ in accordance with ISO 11979.

Radius Measurement
Spherometers
Ultra-accurate measurement of radius of curvature. Our spherometers have become an industry standard for ultra-accurate radius measurement and calibration of test glasses. The long term accuracy and automated features make our spherometers the preferred instruments for laboratory and production environments.

Fully Automated Centration Testing of Aspheres
AspheroCheck UP
Designed for production environments, the AspheroCheck UP is a measurement system that allows the testing of centration and tilt of aspheric surfaces. It stands out through the complete automation of the measurement process. Proven OptiCentric® measurement technology is integrated for a highly accurate centration testing. The automated positioning of the aspheric sample under test as well as of the non-contact sensor for the off-axis tilt measurement provide the key factors for a fast and precise test result.
