The CAPRIS CMS2 Contrast Measurement System

The CAPRIS Contrast Measuring System 2 (CMS 2) has been designed specifically for off line contrast measurement of laser generated marks on electrical wiring or fibre optic cabling employed in aerospace and other critical industries.

It provides a convenient Quality Assurance tool that can be employed simply and quickly to monitor and measure the average contrast of user applied and/or manufacturer markings on wire and cable.

The CMS 2 calculates the contrast by measuring the variation in luminance on the surface of a sample over an area encompassing the mark and the unmarked insulation. Driven through Windows software (supplied with the system) with a full file management capability, the contrast of a sample is measured accurately and calculated in a single measurement at the click of the mouse. The operator then has the option to store the contrast result and the sample information on file.

In addition, the CMS 2 data can be used in SPC systems recording contrast vs time/wire manufacturer and wire gauge. The system is also able to measure contrast repeatably and efficiently (independent of time or the operator) and provide a record of the measurements for quality tracking purposes.

The latest aerospace wiring standards MILW-22759/80-92 specify a mark contrast requirement and the CMS 2 can verify that the wire marking process complies with this standard and monitor quality.
