Witness pieces are used to test and/or confirm the optical properties of the coating that is applied to the substrate. They are also used to test the durability of the coating. They need to have the same characteristics as the optic being coated, and most often must be comprised of the same material as the optic.
Minimum order quantity may apply. Custom sizes and other material also available.
