48-399 25 mm Dia. 70:30 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm

The 48-399 is a 25 mm diameter beamsplitter, specifically designed for use in the near-infrared (NIR) spectrum, with a wavelength range of 700-1100nm. This beamsplitter is sourced from Edmund Optics, a leading global manufacturer of optical components.

The beamsplitter is made from N-BK7, a high-quality borosilicate glass commonly used in optical systems due to its excellent optical properties. The glass has a thickness of 3mm, providing durability and stability. The beamsplitter is designed to reflect 70% of the incident light and transmit 30%, offering a 70:30 (R:T) split ratio.

The front surface of the beamsplitter is coated with EDM 48-395, a proprietary coating developed by Edmund Optics. This coating enhances the beamsplitter's performance in the NIR spectrum, ensuring optimal operation within its specified wavelength range.

The beamsplitter is shaped as a thin lens, allowing for easy integration into various optical systems. Its circular geometry, with a diameter of 25mm, further adds to its versatility, making it suitable for a wide range of applications.
