Case 5: Lapping and Polishing Optical Devices

We have developed a number of process applications for optical device boards, optical fiber, optical waveguides, laser crystals, polarization devices, optical crystals, etc., that are indispensable for optical communication.

It is necessary for optical device components to design the fixture that matches the profile of the workpiece to be lapped and polished because the optical device components require lapping and polishing of flat, spherical, and angle surfaces.
