Reticles manufacturing is a specialized industry that involves the production of precision optical components used in a variety of applications, including microscopy, imaging, and semiconductor manufacturing. Reticles are essentially patterned glass plates that are used to measure and align optical systems. They are commonly used in microscopes, telescopes, and other optical instruments to provide a reference point for measurements and to help align the optical components. The manufacturing process for reticles involves a range of precision machining and polishing techniques to ensure that the final product meets the required specifications.
