Capabilities

Golden Way Scientific's beamsplitters are manufactured from a wide variety of SCHOTT, Ohara, and CDGM materials. Whether you require several beamsplitters for prototyping, a few dozen for pre-production, or large quantities for mass production, we can develop a solution tailored for your application. Some values may depend on material and the other required specifications.
