Beamsplitter Plates NIR, Rectangular
LINOS® Rectangular NIR beamsplitter plates provide precise optical path control in near-infrared optical systems, covering a broad spectral range from 700 to 1200 nm. Made from high-quality N-BK7 glass, each plate features a second-surface broadband AR coating (ARB2 NIR) to maximize transmission efficiency and minimize reflections. Standard models exhibit balanced 50:50 reflectance and transmittance for unpolarized light at 45° angle incidence.
These plates offer a high damage threshold, making them well-suited for laser, imaging, and spectroscopy applications that demand robust, low-loss performance. For larger quantities or specific needs, including alternative sizes, materials, or coatings, please contact us for customized solutions.
