Savvy Inspector™The perfect blend of innovative design and state of the art technology

  • M3 Measurment Solutions - The SavvyInspector™ provides software assisted scratch/dig evaluation

Savvy Inspector™

The inspection station allows an objective measurement of scratch and dig visibility. Available in multiple configurations, including standard and high-resolution, and large stage options.

The SavvyInspector™ provides software assisted scratch/dig evaluation of flat optical surfaces, eliminating the subjectivity of human surface quality inspection. The instrument is designed specifically to reproduce the conditions of an in-reflection visual inspection described in Appendix C of MIL-PRF-13830B, “General specification governing the manufacture, assembly, and inspection of optical components for fire control instruments.” The factory calibrated inspection head of the SavvyInspector™ uses invariant illumination and detection optics and propriety analysis software, allowing objective, repeatable, and recordable evaluation of scratch/dig surface quality.

System Operation
A typical inspection involves a visual scan of the surface using a high- intensity fiber lamp, to generate a quick surface map of imperfections that are to be evaluated. When mapping the surface, a qualified inspector can also record the scratch lengths to be to be used for accumulation. The part is then loaded into the SavvyInspector™ and each defect is evaluated based on the selected calibration standard. Defect images can be stored if desired. The operator then enters the values of the surface imperfections onto the surface map or into the SavvyAccumulator™, a free-ware spreadsheet also provided with the instrument, which reports whether the part passes or fails the surface quality inspection. The accumulator page can be printed or saved into the same location as the defect images for future review.

The SavvyInspector™ operator interface is designed for easy factory-floor operation. Inspection mode allows the operator to perform a surface quality scratch or dig evaluation based on a pre-recorded calibration file. There are no knobs to turn, keys to press, or adjustments required; the operator simply uses the manual x-y stage to locate the desired defect on the real- time viewing screen, and read the scratch/dig value off the screen in real- time. The resultant image file can be stored for later review or printed to be included in an inspection report.

Instrument Calibration The SavvyInspector™ software comes from the factory with calibration files based on all the most common and respected comparison standards manufactured by Brysen Optical, Davidson Optronics, and Jenoptik. Sets of calibration artifacts have been sequestered in order to guarantee instrument to instrument agreement during the manufacture of each SavvyInspector™. If the user needs a scratch inspection done to a standard which is not in the factory calibrations library, a custom calibration file can be created. The tool owner just enters the password protected calibration mode, presents the SavvyInspector™ with the desired comparison artifact, and enters the measured visibility into the appropriate data field for that scratch number. The calibration data can then be saved and accessed from the inspection mode. No changes can be made to factory calibration data.
