1. The reticle has high surface quality requirement, any tiny dust will produce very big black dot in the observation, and the installation position of reticle high accuracy requirement.

2. The reticle commonly adopt the way of chromium plating and etching formation division meters, line adopts chromium plating method, luminous type is filled with titanium oxide and zinc oxide powder after etching.

3. The line precision can reach + / - 0.002 m from RAYS, are widely used in medical and military fields.

4. For special use reticle, RAYS can be customized anti-reflection, waterproof, hydrophobic oil and anti glare layer, etc.
