48-397 12.5 x 17.5 mm 70:30 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm

The 48-397 is a 12.5 x 17.5 mm N-BK7 Plate Beamsplitter, designed for use in the near-infrared (NIR) spectrum, specifically between 700 and 1100nm. This beamsplitter is manufactured by Edmund Optics, a leading provider of optical components.

The beamsplitter has a reflection-to-transmission ratio of 70:30 (R:T), meaning it reflects 70% of the incident light and transmits 30%. This ratio is consistent across the specified NIR spectrum, ensuring reliable performance.

The beamsplitter is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties. The glass has a thickness of 3mm, providing durability while maintaining a low profile.

The coating on the front surface of the beamsplitter is EDM 48-395. This coating enhances the beamsplitter's performance in the NIR spectrum, ensuring efficient and reliable operation.

The beamsplitter's rectangular shape and thin lens design make it suitable for a wide range of applications, including imaging systems, interferometers, and other optical instruments.

According to the vendor's website, the 48-397 is currently in stock, ensuring quick delivery for your optical project needs.
