68-427 35 x 35 mm 80:20 (R:T) N-BK7 Plate Beamsplitter; t=3mm VIS 400-700nm

The 68-427 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 35 x 35 mm, and has 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 a 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 and has the Edmund Optics designation 68-417. The coating is specifically designed for use in the visible light spectrum, ensuring optimal performance in this range.

The beamsplitter's thin lens shape allows for easy integration into optical systems, while its robust construction ensures long-term reliability and performance.
