48-393 25 x 38 mm 30:70 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm

The 48-393 is a rectangular beamsplitter, measuring 25 x 38 mm, with a thickness of 3mm. It is manufactured from N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties. This beamsplitter is designed for use in the near-infrared (NIR) region, specifically between 700 and 1100nm.

The beamsplitter has a reflection ratio of 30:70, meaning it reflects 30% of the incident light and transmits 70%. This ratio is consistent across the entire NIR spectrum, making it a reliable component for applications that require consistent light splitting.

The front surface of the beamsplitter is coated with EDM 48-389, a coating specifically designed to enhance its performance in the NIR region. This coating ensures high transmission and low reflection, making it ideal for use in applications such as laser systems, interferometry, and bio-imaging.

The beamsplitter's thin lens shape allows for easy integration into optical systems. It is currently in stock and available for purchase from Edmund Optics, a leading vendor in the optical industry. For more information, please refer to the provided weblink.
