68-413 50 x 75 mm 60:40 (R:T) N-BK7 Plate Beamsplitter; t=3mm VIS 400-700nm

The 68-413 is a high-quality beam splitter from Edmund Optics, designed for use in the visible light spectrum, specifically between 400 and 700nm. This beam splitter is rectangular in shape, with dimensions of 50 x 75 mm, and has a thickness of 3mm, making it a robust and stable option for various optical applications.

The beam splitter is made from N-BK7, a popular optical glass due to its excellent optical properties and high Abbe number. This material ensures high transmission and low dispersion, making it ideal for applications that require precise and accurate light splitting.

The coating on the front surface of the beam splitter is EDM 68-399, which is specifically designed to enhance the performance of the beam splitter in the visible light spectrum. This coating ensures a 60:40 split ratio for reflected and transmitted light, making it suitable for applications that require a specific balance between reflected and transmitted light.

The beam splitter is in stock and available for immediate purchase from the Edmund Optics website, as indicated by the "weblink status" field in the item data. With its robust construction, high-quality materials, and precise coating, the 68-413 is an excellent choice for a wide range of optical applications.
