Universal Calibration Slide PS20

Calibration of microscopes and image analysis systems is becoming more sophisticated, with the requirement being for a variety of image patterns to satisfy the numerous parameters. We're now introducing a new multi-function calibration standard specifically for these applications.

Multiple images on a slide provide the most cost-effective solution to calibration and resolution checking of microscopes and image analysis systems. The combination of scales, dots, circles, squares, rulings, grids and angles can be supplied with an internationally traceable certificate of calibration for those who require ISO conformity.

Each glass slide has a permanent serial number and can be supplied with full or partial UKAS Certificate of Accuracy.

Starting from a fixed 'Datum Point' mark, each individual pattern or array can be located using X, Y, coordinates.
