Introduction

 

CASTECH has integrated various polishing and coating technologies to address optimized solutions to different applications focusing on ultra-precise finishing with even fine subsurface properties or costs-efficiency. We work closely with our customers on engineering building and mass production of a complete portfolio of optics components including aspherical lens, spherical lens, cylinders, gratings, mirrors, windows, prisms and beamsplitters made out of an extensive range of materials.

By combining manufacturing with our advanced bonding processes, we are able to produce high quality multi-optical elements and optomechanical assemblies. Some typical parts include optical diffusion bonded polarization beamsplitter cubes used in high power laser systems, customized lens solutions like objective lenses, telecentric F-Theta lenses and collimators for a wide range of applications.
