These general purpose plate beam splitters are for use at 45°. Our plate beam splitters are available for both visible, NIR and Telecoms applications. We stock 50/50 plate beamsplitters and 70/30 plate beamsplitters for visible applications such as imaging and 50/50 plate beamsplitters for NIR for use in medical and laser applications and interferometers.
The Beamsplitter multilayer dielectric coating is deposited on standard white float glass that has a relatively good grade of flatness and surface quality. All general purpose grade beamsplitters have a multilayer broad band antireflective coating on the rear to eliminate problematic secondary reflections.
Knight Optical's plate beamsplitters are available in 1mm and 3mm thicknesses. The 1mm thick beamsplitters are useful where compactness and weight are an issue. The white float glass used can be particularly useful in the near infrared plate beamsplitter as it avoids strong IR absorption.
