68-374 35 x 35 mm 20:80 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm

This 68-374 Beamsplitter, sourced from Edmund Optics, is a high-quality optical component designed for use in the near-infrared (NIR) spectrum, specifically between 700 and 1100 nanometers. The beamsplitter is rectangular in shape, with dimensions of 35 x 35 mm, and has a thickness of 3mm.

The beamsplitter is made from N-BK7, a popular optical glass known for its excellent optical properties. This material is often used in a variety of optical applications due to its low dispersion and high homogeneity. The beamsplitter features a 20:80 (R:T) split, meaning that approximately 20% of the incident light is reflected, while the remaining 80% is transmitted.

The front surface of the beamsplitter is coated with EDM 68-364, a proprietary coating developed by Edmund Optics. This coating enhances the beamsplitter's performance in the NIR spectrum, ensuring high transmission and low reflection within the specified wavelength range.

The beamsplitter's thin lens shape allows for easy integration into optical systems, while its robust construction ensures long-term reliability and performance. According to the vendor, the beamsplitter is currently in stock, making it readily available for immediate use.
