OptiSpheric®
The standard for comprehensive testing of optomechanical parameters of lenses
OptiSpheric® is the industry standard for non-contact inspection of basic axial optical and mechanical parameters and is used worldwide to fully measure and qualify single lenses – as well as intraocular lenses – and optical systems. The world’s largest laboratories and major optics manufacturers rely on TRIOPTICS optical inspection systems.
They use the OptiSpheric® for reliable and reproducible axial measurement of effective focal length, back focal length, flange focal length, radius of curvature and modulation transfer function (MTF). Different product variants are available that are optimized for different applications and simplify the measuring process: manual or automated processes in different measuring ranges, the combination with OptiCentric®, measurement at further wavelengths and in-air and in-situ measurement for intraocular lenses. The easy-to-use software allows accurate measurement of the test samples at any time.

OptiSpheric® IOL R&D
Comprehensive testing of IOLs in R&D
The OptiSpheric® IOL R&D allows the testing of intraocular lenses in research and development.
- Quick testing of single lenses in just 12 seconds
- ISO-compliant measurement of hydrophobic and hydrophilic lenses in air or in a heatable in situ eye model according to ISO 11979
- Power measurement with an accuracy of 0.3 % for all types of intraocular lenses
More information
The products of the OptiSpheric® IOL series represent the industry standard for intraocular lens inspection. Customers rely on the high-precision measurements in research and development as well as in production. The transparent measuring process allows the effortless determination of important parameters such as:
- Power (sphere, cylinder und addition)
- Effective focal length (EFL)
- Modulationtransferfunction (MTF and 2D-MTF)
- Pointspreadfunction (PSF and LSF)
- Orientation of the cylinder axis, orthogonality of the optical axis and deviation of the markers from the optical axis
- Radius of curvature (in air)
- Back focal length (BFL, in air)
- MTF focus scan („Through Focus Scan“)
- Energy distribution (MTF area)
- Streh ratio
- Visual inspection
The measuring systems are universally applicable for all types of intraocular lenses (monofocal, spherically aberrated lenses (EDOF), multifocal, trifocal, toric and aspherical IOLs (each diffractive, refractive or sector lens)) and allow the traceability of the measurement results to international, independent testing institutes such as NPL and NIST.
OptiSpheric® IOL PRO 2
Fully automated IOL measurement
OptiSpheric® IOL PRO 2 enables the inspection of intraocular lenses in production.
- High throughput with up to 100 lenses per tray
- ISO-compliant measurement of hydrophobic and hydrophilic lenses in air or in a heatable in situ eye model according to ISO 11979
- Power measurement with an accuracy of 0.3 % for all types of intraocular lenses
