68-385 25 mm Dia. 40:60 (R:T) N-BK7 Plate Beamsplitter; t=3mm VIS 400-700nm

The 68-385 is a 25 mm diameter Plate Beamsplitter from Edmund Optics, designed for use in the visible light spectrum, specifically between 400-700nm. This beamsplitter is made from N-BK7 Schott glass, a popular choice due to its excellent optical properties and wide transparency range.

The beamsplitter features a 40:60 (R:T) split, meaning that 40% of the incoming light is reflected, while 60% is transmitted. This ratio is consistent across the visible light spectrum, making it a reliable choice for a wide range of applications.

The beamsplitter has a thickness of 3mm, which is considered a 'Thin Lens'. This thin design can help minimize unwanted optical effects such as aberrations and distortions. The front surface of the beamsplitter is coated with EDM 68-381, a coating specifically designed to enhance the performance of the beamsplitter in its intended application range.
