Product Overview

Match 25.4 mm Concentric-Ring Reticle groove geometry to dispersion and efficiency

The listed geometry and pattern data should be evaluated with the complete optical system; groove, feature and calibration specifications cannot be inferred from outside dimensions alone.

Choose positive or negative pattern polarity and confirm ring-area dimensions against the imaging field.
