68-424 25 x 25 mm 80:20 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm

This 68-424 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 25 x 25 mm, and has a thickness of 3 mm.

The beamsplitter is made from N-BK7, a popular optical glass known for its excellent optical properties. This material is identified in the item data as "n-bk7 schott", indicating its specific origin and quality. The beamsplitter is coated with "edm 68-418" on the front surface, which is a proprietary coating developed by Edmund Optics.

The beamsplitter is designed to split incoming light with an 80:20 ratio, reflecting 80% of the light and transmitting 20%. This is often denoted as (R:T), where R represents reflection and T represents transmission. This specific beamsplitter is therefore referred to as an 80:20 (R:T) beamsplitter.

According to the item data, this beamsplitter is currently in stock and available for purchase. The web link provided leads to the product page on the Edmund Optics website, where more information, including pricing and shipping details, can be found.
