Uses include checking diameters, orthogonality and offset. Both scales measure from -.40” to +.40” in .01” increments with numerical markings every .1”. The pattern is accurate to .00004”. The pattern is right reading looking through the glass so that the pattern can be in direct contact with the object to be measured.The Reticle Pattern is very durable, double layer, deposited evaporative Chrome/Chrome Oxide, for a reflectivity of less than 5% looking at the pattern. The Patterns on all Reticles manufactured by Max Levy are replicated from Precision Chrome on Glass Tooling under clean room conditions.
