Savvy Inspector®

Scratch and dig inspector

Savvy Inspector® is designed to measure surface imperfections. The factory-calibrated inspection head uses invariant illumination and detection optics and proprietary analysis software to provide an objective, repeatable and recordable evaluation of the surface quality of optical components. It operates in accordance with ANSI/OEOSC OP1.002, Appendix C of MIL-PRF-13830B, Appendix A.3 of ISO 14997, and ISO 10110. It comes with calibration files traceable to the common standards.

Objective

Savvy Inspector® software supports the optic’s surface error detection with little user influence. All commonly available comparison sets, including C7641866, can be selected for providing a direct objective classification of imperfections and judging them as pass or fail.

Reliable

The defined illumination and detection angles make the measurement reliable and consistent even when measurements are performed at different sites. The ring illumination is used to overcome judgement errors traditionally occurring due to part orientation.

Precise

Savvy Inspector’s® large 9 by 12 mm field of view makes it easy to identify the locations of imperfections. A 1 mm² test area is used to classify and grade the imperfection. Defined brightness makes even small imperfections visible.

Software

Savvy Inspector® Software

The Savvy Inspector® operator interface is designed for easy factory-floor operation, while expanding its application in the role of “Master Inspector” for QA, QC and MRB decisions. The operator enters the inspection level required, and then uses the manual x-y stage or the joystick to locate the desired defect on the real-time viewing screen. In motorizied systems the “autoscan” feature creates indexed image files for the entire surface, documenting the condition of the optic and allowing the operator to identify regions on the part which require further review. The coordinates can be entered and the system returns to the desired location with the push of a button.

The software reports the scratch grade or dig value automatically. Scratch lengths are measured with the click of the mouse. The “always on” inspection mode and programmable grade bars allow the operator to get real-time feedback on whether a selected imperfection is acceptable or not with a simple visual interface.

For careful review and documentation of a lens surface, Savvy Inspector® software offers data management tools. These allow the proper capture and archiving of screenshots as well as the grade for each error on a surface. Additionally, a summary log in CSV format or an inspection report is generated.

Accumulation rules can be applied using the SavvyAccumulator™ spreadsheet. Custom calibration files can be created for specific project or customer needs by the Quality Engineer as needed. The calibration data can then be saved and accessed from the inspection mode.
