68-429 50 x 50 mm 80:20 (R:T) N-BK7 Plate Beamsplitter; t=3mm VIS 400-700nm

The 68-429 is a high-quality beamsplitter from Edmund Optics, designed for use in the visible light spectrum, specifically between 400 and 700nm. This beamsplitter is rectangular in shape, with dimensions of 50 x 50 mm, and a thickness of 3mm, making it suitable for a wide range of optical applications.

The beamsplitter is made from N-BK7 glass, a popular material in optical systems due to its excellent optical properties and high damage threshold. The N-BK7 Schott material ID ensures that the glass meets the stringent quality standards set by Schott, a leading manufacturer of optical glass.

The beamsplitter features an 80:20 (R:T) coating, which means that 80% of the incident light is reflected, while 20% is transmitted. This coating is applied to the front surface of the beamsplitter, as indicated by the "edm 68-417" coating parameter. The coating is specifically designed for use in the visible light spectrum, ensuring optimal performance in this range.

The beamsplitter is classified as a thin BS, or thin beam splitter, due to its thickness. This design allows for minimal beam deviation, making it ideal for applications where beam direction is critical.
