Antipolarizing spectroscopic prism

• Base material: K9
• Sizes: 5×5mm, 6×6mm, 10×10mm, 12.7×12.7mm, 15×15mm, 20×20mm, 25.4×25.4mm
• Band range: 420-700nm, 600-900nm, 633nm, 700-1000nm, 900-1200nm, 1200-1600nm
• Spectral ratio (T:R): 45:45±5%
• Hybrid coating design, absorbing < 10%
• The spectral ratio is insensitive to the polarization state of the incident light

The Beamsplitter Cube consists of two right-angled prisms connected by beveled edges and coated at the interface for beamsplitter. Compared with the spectroscope, the reflected light and the transmitted light of the spectroprism are equal, and there is no problem of beam translation, ghosting and interference. Dimension-Labs offers Non-Polarizing Beamsplitter Cubes with K9 as the base material and are available in a variety of sizes and bands (420-700nm, 600-900nm, 633nm, 700-1000nm, 900-1200nm, 1200-1600nm).

The spectroscopic film of the antipolarizing spectroscopic prism adopts a metal-dielectric hybrid film system, so the outgoing and incident light have the same polarization state. It should be noted that antipolarizing spectroscopic prisms have low polarization, but this type of metal medium hybrid film layer has a certain absorption of incident light (usually < 10%), so it is recommended not to use it in strong laser energy environments.
