Beamsplitter Plates NIR, Circular
Our LINOS® circular NIR beamsplitter plate is designed for precise splitting or combining of beams in near-infrared optical systems, spanning a broadband range from 700 to 1200 nm. Fabricated from high-quality N-BK7 glass, it features a second-surface broadband AR coating (ARB2 NIR) to minimize reflections and maximize transmission efficiency. Our standard model provides a 50:50 balance of reflectance and transmittance for unpolarized light at 45° angle incidence. With a high damage threshold, these plates are ideal for robust laser, imaging, and spectroscopy applications requiring reliable, low-loss performance.
