OptiCentric®

High-precision centration test devices, alignment, cementing and bonding systems

The OptiCentric® product group represents the global standard for optical centration testing and manual and automated cementing and bonding of lenses and lens assemblies. With its extremely high degree of centration accuracy and integrated operation, OptiCentric® systems are indispensable in modern optics productions. It makes no difference whether the sample has a small or very large diameter, works in the visual or infrared spectral range, or is to be cemented, bonded or just measured: modular OptiCentric® systems permit a wide range of different applications and samples for optimum composition.

Precise

With the OptiCentric® absolute accuracy of 0.1 µm can be achieved for the measurement and production of maximum performance optics. The MultiLens® software module also makes quality checks on complex lens assemblies possible.
 

Flexible

Thanks to a comprehensive selection of optics, adaptation to the sample and measuring situation is possible in UV, VIS and IR as well as for spherical, aspherical and cylindrical lenses and lens assemblies in a diameter range from 0.5 mm to 800 mm.

Sophisticated

The alignment, cementing and bonding of lens elements in production can take place both manually and automatically. The lens edge or – thanks to the patented OptiCentric® software module SmartAlign – the optical axis of a lens can be used as a reference for alignment.

Products

The size of the sample – in particular diameter and weight – has a major influence on the composition of units used. The base unit is generally selected on the basis of these criteria. The functionality of each base unit can be further enhanced (Expansion stages).

To make measurement of these different sample dimensions possible, the measurement head is mounted to a height-adjustable stage.  The measurement point of the autocollimator measurement head can be moved flexible and precisely into the measurement position of the sample by a motorized fence. The entire measurement process, for example for measurement and alignment of multilens assemblies, can be fully automated.

Software

The user of an OptiCentric® system controls the entire measurement, alignment and cementing process via the OptiCentric® software. This software controls the components – no matter whether standard or optional module – and the measurement process. Measurements and evaluations take place easily, quickly and highly accurately. The integrated static analysis permits reliable and standardized evaluation as well as output of measurement certificates.

Upgrades

A precise pivot bearing represents the measuring reference of high-precision centration testing. All OptiCentric® systems are equipped with an air bearing, optionally a mechanical lens rotation device can be used for measurement of single lenses and doublets.

An OptiCentric® system equipped with an air bearing is required for the following applications:

  • Testing lens assemblies
  • Setting up lens assemblies
  • Alignment of doublets with the optical axis of the lower lens as reference
  • Alignment and centering of lenses on a centering arbor with the arbor axis as reference
  • Testing of aspheres using the AspheroCheck® module
  • Single lens measurement on sensitive lenses e.g. calcium fluoride lenses

 

OptiCentric® 3D detail

Manual tip-tilt table (TRT)

OptiCentric® systems use tip-tilt tables to align samples. The decoupled movements of the tip-tilt tables allow for precise positioning of the sample or sample holder. Tip-tilt tables are available in different diameters for a variety of applications and measurement systems.

Motorized tilt and translation table (TRT)

Motorized tilt and translation table (TRT)

For easier sample handling during measurement or setup of an optical system, the OptiCentric® 3D 100 in particular can be equipped with a tilt and translation table (TRT). Instead of the traditional manually alignement, the motorized TRT tilts and shifts the sample such that the optical axis of the lens is aligned to match the reference axis of the system. This is performed fully automated and embedded in the process flow, thus permitting a shortened test cycle.

Lens rotation device

Lens rotation device

The motorized rotation device is a rotation device to

  • measure single lenses with a diameter up to 200 mm using the outer edge and the center of curvature of the lower lens as a reference
  • cementing doublets. In this case, the reference axis comprises the center of the circumference and the center of curvature of the lower lens.

No air bearing is required for the motorized rotation device. Equipped with a so-called “bridge”, the lens rotation device can be operated on OptiCentric® 100, 101 and 300 units which are equipped with an air bearing.
