Penta Beamsplitter Cubes

Beamsplitters are used to split or combine beam of light. The most common types provided by Z-Optics Technologies Inc.: plate and cubes. Plates are used for most laser applications as they exhibit low absorption. Cubes are a convenient, protected form for low power applications. Pellicles are very thin membranes which do not produce interference from secondary reflections. The performance of beamsplitters are mainly depended on the coating specifications.
