Beamsplitter Plates VIS-NIR, Rectangular
LINOS® Rectangular VIS-NIR beamsplitter plates offer precise light path control for broadband applications within the 450–1000 nm range. Each plate is made from high-quality N-BK7 glass and includes a second-surface broadband AR coating to reduce reflections and maximize transmission. Standard models deliver balanced 50:50 reflectance and transmittance for unpolarized light at 45° incidence. Wedge versions are also available to prevent etalon effects.
These plates are ideal for spectroscopy, imaging, and laser applications, offering reliable, low-loss performance and consistent optical behavior. For larger quantities or specific needs such as alternative sizes, materials, or coatings, contact us for a customized solution.
