SHSInspect 2Xpass

All-in-one test platform for comprehensive testing of lens assemblies and objective lenses at field points

Benefits

Wavefront measurement on- and off axis
Accuracy lambda/20 peak-to-valley
Semi-automatic measurement processes
Measurement of chromatic effects
Measurement of polarization effects

The turnkey all-in-one test platform SHSInspect 2Xpass enables semi-automatic, high-precision wavefront measurement of lenses at different wavelengths – on axis and at field points. The devices are used, e.g. for testing smartphone optics and photo lens assemblies as well as for immersion microscope objective lenses. The range of functions includes:

Trasmitted wavefront at field points
Semi-automated measurement processes
Acquisition of wavefront, Zernike, PSF and MTF
Measurement of focal length and field curvature
Analysis of chromatic effects
Investigation of polarization effects

The objective lens to be tested is illuminated with a plane wave and measured against a spherical reference mirror. For the measurement of the transmitted wavefront in the field, the plane wave illumination is realized at a defined angle. The spherical mirror is shifted laterally accordingly. After manually adjusting the optical system under test, the measurement is carried out semi-automatically. The SHSInspect 2Xpass is equipped with various light sources to enable the analysis of chromatic effects.

The SHSInspect 2Xpass is configured depending on the application and the properties of the lenses to be tested. The system can be equipped with up to 6 light sources from 355nm to 1064nm. The switching of the light source is motorized.

The SHSInspect 2Xpass uses Optocraft’s powerful Shack-Hartmann software SHSWorks for Zernike analysis and PSF/MTF calculations. It is enhanced with extensions for semi-automatic measurement and the integration of vision control cameras.

As a global leader in production of high precision optics and systems for demanding customers, e.g. in the semiconductor or medical field, every day we are working at the limit of what is feasible. Oftentimes, metrology for online quality control of our products during manufacturing, assembly or during the final testing is not commercially available. Therefore, we depend on partners who develop an deliver customized innovative metrology solutions. This requires a high degree of creativity, know-how in physics and a maximum amount of flexibility. Also wenn facing demanding tasks, Optocraft fulfills these requirements with strong personal commitment and in a professional way.
