Laser Polarizing Beamsplitters Cube

Laser polarizing beamsplitter cubes are thin-film polarizers constructed in a cube form, designed to manage polarized light effectively. These beamsplitters achieve high extinction ratios by utilizing multiple reflections within their structure. The polarization state of the incident light is manipulated so that s-polarized light is more than 99% reflected, while p-polarized light is transmitted at approximately 95%.

Engineered with dielectric coatings, these polarizing cube beamsplitters are optically contacted to maintain superior performance at laser wavelengths. They are particularly suited for high power lasers due to their ability to handle intense energy without compromising polarization purity. Optimized for specific laser wavelengths, these cubes are ideal for applications requiring precise control over polarization, ensuring minimal losses and high efficiency in separating the two polarization states.
