48-909 75 x 75 mm 70:30 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm

The 48-909 is a 75 x 75 mm rectangular beamsplitter, designed with a 70:30 (R:T) ratio, making it ideal for applications that require a higher reflection rate. This beamsplitter is made from N-BK7 Schott glass, a popular choice due to its excellent optical properties and high damage threshold. The beamsplitter has a thickness of 3mm, providing robustness and stability.

The beamsplitter is designed for use in the near-infrared (NIR) region, specifically between 700 and 1100nm, making it suitable for a wide range of applications including biomedical imaging, laser spectroscopy, and optical communication systems. The front surface of the beamsplitter is coated with EDM 48-395, a coating specifically designed to enhance its performance in the NIR region.

The beamsplitter's physical data indicates a reflection rate of 0.7 and a transmission rate of 0.3. This means that 70% of the incident light will be reflected, while 30% will be transmitted. This ratio is consistent across the entire NIR region, ensuring predictable and reliable performance.

This beamsplitter is available from Edmund Optics and is currently in stock, making it a readily available solution for your optical system needs. For more information, including detailed specifications and purchasing options, please refer to the provided weblink.
