Beamsplitter Plates with Different Splitting Ratios
LINOS® Beamsplitter plates with various splitting ratios enable precise control of beam distribution in visible-wavelength optical systems. Optimized for 45-degree angles of incidence, these plates incorporate TBP broadband beamsplitter coatings and a second-surface broadband anti-reflection coating to achieve low-loss and high-efficiency performance. Manufactured from high-quality N-BK7 glass, they provide a large clear aperture and strong mechanical stability, making them suitable for rigorous laboratory and industrial environments.
Various reflectance and transmittance ratios enable flexible beam splitting or combining, while plate tolerances ensure reliable integration. Standard 50:50 plates are detailed in the VIS-NIR section, and modified ratios or wavelength ranges can be provided for larger quantities upon request, offering flexible, tailored solutions for advanced, customized optical setups.
