68-383 12.5 x 17.5 mm 40:60 (R:T) N-BK7 Plate Beamsplitter; t=3mm VIS 400-700nm

This 68-383 Beam Splitter, sourced from Edmund Optics, is a high-quality optical component designed for use in the visible light spectrum, specifically between 400 and 700 nanometers. The beamsplitter is rectangular in shape, with dimensions of 12.5 x 17.5 mm, and has a thickness of 3mm, providing robustness and stability in its operation.

The beamsplitter is made from N-BK7, a popular optical glass due to its excellent optical properties, including a high Abbe number and low dispersion. This makes it an ideal choice for applications that require high-precision optical performance.

The coating on the beamsplitter is EDM 68-381, which is specifically designed to provide a 40:60 (R:T) split for the visible light spectrum. This means that 40% of the incident light is reflected, while 60% is transmitted, offering a balanced split for many optical systems.

The beamsplitter is in the form of a thin lens, which helps to minimize unwanted reflections and scattering, further enhancing its performance. The physical data of the beamsplitter indicates a reflection of 0.4 and a transmission of 0.6, aligning with the specified coating.
