68-428 35 x 35 mm 80:20 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm

This 35 x 35 mm 80:20 (R:T) N-BK7 Plate Beamsplitter is a high-quality optical component sourced from Edmund Optics. It is designed for use in the near-infrared (NIR) spectrum, specifically between 700 and 1100 nanometers. The beamsplitter is 3 millimeters thick and features a rectangular shape, making it suitable for a wide range of optical applications.

The beamsplitter is made from N-BK7, a popular optical glass known for its excellent optical properties. This material is often used in high-precision optical systems due to its low dispersion and high homogeneity. The beamsplitter's coating, edm 68-418, is applied to the front surface and is specifically designed to optimize performance in the NIR spectrum.

In terms of its optical properties, the beamsplitter has a reflection ratio of 80:20 (R:T), meaning it reflects 80% of the incident light and transmits 20%. This ratio is fixed and does not vary across the specified NIR spectrum. The beamsplitter's thin lens shape further enhances its versatility, making it a reliable choice for various optical systems.
