It can also be used to gauge the straightness, edge acuity and perpendicularity of lines and features. The pattern is on the contact surface, right-reading looking through so that the object can be measured directly.The Reticle Pattern is very durable, double layer, deposited evaporative Chrome/Chrome Oxide, for a reflectivity of less than 5% looking at the pattern.
