This reticle is used for accurate angle measurement and alignment functions. The 360 degree protractor has divisions every 1 degree with numerical labels every 10 degrees. The protractor pattern is accurate to within 1 arc-second. A solid-line crosshair marks the middle of the reticle, providing for accurate alignment. The line widths are 0.001”± 0.0001”.
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.
