68-432 50 x 75 mm 80:20 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm

The 68-432 50 x 75 mm 80:20 (R:T) N-BK7 Plate Beamsplitter is a high-quality optical component sourced from Edmund Optics. This beamsplitter is designed for use in the near-infrared (NIR) spectrum, specifically between 700 and 1100 nanometers.

The beamsplitter is rectangular in shape, with dimensions of 50 x 75 millimeters, and has a thickness of 3 millimeters. It is made from N-BK7 glass, a popular material in optical systems due to its excellent optical properties and wide transparency range. The beamsplitter is coated with EDM 68-418 on the front surface, which contributes to its specific reflectance and transmittance characteristics.

In terms of its optical performance, the beamsplitter has a reflection ratio of 80:20 (R:T), meaning it reflects 80% of the incident light and transmits 20%. This makes it ideal for applications where a significant portion of the light needs to be reflected while still allowing some light to pass through.

The beamsplitter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its weblink status. This information, along with other relevant details, can be found in the item data provided.
