White Glass Reticles, Resolution Charts, Scales, Dot Arrays and Chequerboards
For many vision applications a high contrast image made using different types of chrome coatings on a white glass gives far better results. Graticules offer Reticles, Resolution Test Targets, Ronchi Rulings, Calibration Scales, Dot Arrays and Chessboards all made on white glass.
We have numerous standard products and the option of having a custom pattern to your exact requirements.
