“Aspheres”: Aspheric analysis in spherical or CGH setups
- The asphere module permits the analysis of strong aspheres in an aspherical setup with the help of a computer-generated hologram (CGH) as well as the analysis of weak aspheres in spherical setups. A description of the asphere can be entered and saved. Various formats (rotationally symmetric) are supported. Remaining adjustment errors as well as systematic setup errors are compensated by an aspherical adjustment fit.
“Cylinder”: Cylinder analysis
- The cylinder module analyzes cylindrical samples in a cylindrical setup (with CGH). Remaining adjustment errors are compensated by a cylindrical adjustment fit.
“Extern Interface“: External communication interface
- The external interface module allows communication between µShape™ and external software such as LabVIEW™ for controlling the interferometer through external programs, e.g. within an automated system
“FastFringe“: Static fringe analysis
- This module enables the analysis of a single interferogram for measurements in instable environments or with interferometers without phase shifting device.
“Fiber connector“: Fiber optic connector analysis
- The fiber connector module allows the analysis of the end faces of fiber optic connections type PC (physical contact) as per the international IEC convention. The main parameters are gathered with just one measurement; this includes an optional display of a pass/fail analysis.
“Homogeneity“: Measurement of the homogeneity of transparent samples
- Both aspects influencing the optical path through the sample, i.e. homogeneity (variation of the refractive index) on the one hand, and thickness variation on the other hand, can be determined in a separate program mode.
“Math Mode”: Mathematic mode
- This program mode permits the analysis of various data assignments in combination with mathematical calculations to an additional assignment of results. Matrix calculations are not possible.
“Multiple apertures“: Multiple aperture analysis in one step
- This module permits the joint measurement and analysis of individual unconnected apertures within a field of view, e.g. for the measurement of components mounted on polishing heads.
The possibility of simultaneous measurement of non-connected apertures also enables a wedge analysis. This analysis can be used to determine the wedge angle of flat mirrors as well as the optical wedge of flat transfer plates with an additional mirror behind the object in one step.
“Multiple statistics“: Identical statistical analysis on multiple subapertures
- If the sample specification defines different limits for different sub-sections of the same sample, the MultiStat module allows identical analysis for all subareas within a single measurement. The results for each section are issued separately.
“MTF/PSF“: MTF analysis
- In the field of optics, MTF is used to describe the quality of optical systems. The module permits to calculate the MTF of focal and afocal optical components and systems
“Prisms“: Prism analysis
- Angular errors on 90° and triple prisms can be measured interferometrically by analyzing the interference patterns observed through error deviation on 90° or 0° target angles.
“Roughness / PSD”: Analysis of roughness and PSD
- This module allows to calculate the power spectral density (PSD) as well as roughness parameters along a freely definable straight line.
“Sample Normal Data“: Consideration of known sample deviations
- The use of sample data (Sample Normal Data – SND) allows the identification of additional sample errors and include them in testing, e.g. deviations due to the optical design (design-based nominal values).
