Batch Measurement Module

Our productivity tool kit, offers a unique advantage for batch testing when measurement speed and throughput is a must. Easy set-up, test and analysis for single or multiple parts make this the perfect system for fast and accurate testing of optical components.

Enhanced capabilities and software architecture support high speed measurements of mobile device lenses, ophthalmic lenses, medical and fibre optics, high power LEDs and wafer lens arrays. Loading and programming one lens or a batch of hundreds is made easy and guarantees accurate results with automatic alignment, measurement and analysis.

The Form Talysurf® PGI Freeform enables extraction of individual part profiles from a continuous measurement of an array of parts. Measure dense lens arrays quickly and accurately, with intelligent profile extraction to ensure the correct clear aperture is always analysed.

Simple set-up, measurement and analysis of complex arrays

Define the Array Layout, selecting the part design - Low density, PCD, Wafer, etc.

Formats for measured and analysed data are easily chosen, with option to store results in location of choice

Select location for storing the results

Select ‘Batch’ to measure

Live feedback on measurement pass / fail with clear indication

Automated analysis shows batch results statistics - Allows individual part results to be explored

Define complete measurement offline and transfer to the instrument for the measurement

Completed measurements can be reviewed and re-analysed offline by simply transferring the results folder
