49-756 35 x 35 mm 70:30 (R:T) N-BK7 Plate Beamsplitter; t=3mm VIS 400-700nm

This 49-756 Beamsplitter, sourced from Edmund Optics, is a high-quality optical component designed for use in the visible light spectrum, spanning 400-700nm. It boasts a rectangular shape, with dimensions of 35 x 35 mm, and a thickness of 3mm, making it a versatile choice for various optical applications.

The beamsplitter is constructed from N-BK7, a popular optical glass known for its excellent optical properties. This material is particularly suitable for use in the visible spectrum due to its low dispersion and high transmission. The beamsplitter features a 70:30 split ratio, meaning that approximately 70% of the incident light is reflected, while the remaining 30% is transmitted.

The front surface of the beamsplitter is coated with EDM 48-394, a coating specifically designed to enhance the beamsplitter's performance in the visible light spectrum. This coating ensures high reflectivity and transmission, contributing to the overall efficiency and effectiveness of the beamsplitter.
