Description
Our thin film coatings offer precision and reliability, tailored to meet the unique demands of optical applications. Among these coatings, our plate beamsplitters stand out as essential components for manipulating light paths in various optical systems. These beamsplitters are expertly designed to split a beam of light into separate paths, providing flexibility in the percentages of transmission and reflection, as well as the wavelength region, to suit specific applications.
The first surface of our plate beamsplitters features an all dielectric coating, ensuring optimal performance and durability. To further enhance functionality, the second surface is typically antireflection coated, which significantly reduces secondary reflections and ghosting. We offer customization options to optimize the coating according to your specifications, including the reflection/transmission (R/T) ratio, angle of incidence, and wavelength.
For example, we recently fulfilled a requirement for a plate beamsplitter with a 25% reflection and 75% transmission ratio at an average polarization of 550nm on float glass at a 45° angle. Additionally, another customer specification called for a 50/50 ±5% split at 1.06µm, with greater than 20% reflection in the visible spectrum at a 45° angle on BK-7 glass. These examples illustrate our capability to deliver precise and customized solutions for diverse optical needs.
