48-391 12.5 x 17.5 mm 30:70 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm
This 48-391 Beam Splitter, sourced from Edmund Optics, is a high-quality optical component designed for use in the near-infrared (NIR) spectrum, specifically between 700 and 1100 nanometers. The beamsplitter is rectangular in shape, with dimensions of 12.5 x 17.5 millimeters, and has a thickness of 3 millimeters.
The beamsplitter is made from N-BK7, a type of borosilicate glass manufactured by Schott AG, which is known for its excellent optical properties and durability. This material is particularly suitable for applications that require high precision and low optical loss.
The beamsplitter features a 30:70 (R:T) coating, which means that it reflects 30% of the incident light and transmits 70%. This coating is applied to the front surface of the beamsplitter and is identified as EDM 48-389 in the vendor's catalog.
The beamsplitter's physical data indicates that it has a reflection of 0.3 and a transmission of 0.7, which aligns with the specified 30:70 (R:T) coating. This beamsplitter is a Thin Lens type, which refers to its shape and the way it manipulates light.
