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. Pyser-SGI has introduced a new multi-function calibration standard specifically for these applications. This slide is designed for measurement calibration of microscopes and machine vision systems.
Multiple images on a single 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 unique 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.
Patterns include:
- Concentric circles and squares
- Line gratings, grid and dot arrays
- Geometric root 2 progression of dots and square blocks
- Coarse and variable fine linear line scales
