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 Nextrema® white glass.
We have numerous standard products and the option of having a custom pattern to your exact requirements.
