Beamsplitter Plates UV
LINOS® UV beamsplitter plates deliver high-precision control of light paths within ultraviolet photonic systems, operating from deep UV through to near UV. Available in rectangular, circular, and elliptical formats, these plates provide flexible integration options for diverse experimental setups. With multiple splitting ratios, including balanced and unbalanced R:T options, they enable tailored beam distribution to meet specific application requirements. Designed for 45° incidence, each plate features a second-surface antireflective coating (ARB2 UV) to minimize losses and maximize transmission efficiency.
Ideal for laser systems, spectroscopy, and imaging applications, these UV beamsplitter plates offer reliable performance, low optical distortion, and consistent, reproducible results, making them an essential component in advanced UV optical setups.
