68-363 12.5 mm Dia. 20:80 (R:T) N-BK7 Plate Beamsplitter; t=3mm VIS 400-700nm

This is a 12.5 mm diameter Beam Splitter, specifically a Thin BS, sourced from the reputable optical vendor, Edmund Optics. The beamsplitter is designed with a circular base shape and a thickness of 3mm, making it a robust and reliable choice for various optical applications.

The beamsplitter is made of n-BK7 Schott, a high-quality optical glass known for its excellent transmission properties in the visible spectrum. This specific beamsplitter is designed to operate within the visible light range, from 400nm to 700nm, making it suitable for a wide range of applications where visible light is involved.

The beamsplitter features a coating on the front surface, identified as edm 68-363. This coating is designed to provide specific reflectance and transmittance properties, with a reflection rate of 20% and a transmission rate of 80%. This makes it an ideal choice for applications where balanced light splitting is required.

The beamsplitter is designed in the shape of a Thin Lens, which can provide additional functionality in certain optical setups. The physical data provided indicates that the beamsplitter has a reflection of 0.2 and a transmission of 0.8, aligning with the specified coating properties.
