Introduction to the Traditional Polishing Process of Optical Lenses
During we polish the lenses, the lens may be tested to confirm that the desired shape is being produced, and to ensure that the final shape has the correct form to within the allowed precision. Precision lenses VY manufacture for use in applications such as lasers, interferometers, and holography have surfaces with a tenth of a wavelength (λ/10) tolerance or better.
