47-024 12.5 mm Dia. 50:50 (R:T) N-BK7 Plate Beamsplitter; t=3mm NIR 700-1100nm

The 47-024 12.5 mm Dia. 50:50 (R:T) N-BK7 Plate Beamsplitter is a high-quality optical component sourced from Edmund Optics. This beamsplitter, with a diameter of 12.5 mm, is designed to split incoming light beams equally, offering a 50:50 reflection-to-transmission ratio.

The beamsplitter is made of N-BK7, a widely used optical glass known for its excellent optical properties. The glass plate has a thickness of 3mm, providing sufficient structural integrity while maintaining minimal optical distortion. This beamsplitter is specifically designed for use in the near-infrared (NIR) spectrum, with a wavelength range of 700-1100nm, making it suitable for various applications in this spectral region.

The front surface of the beamsplitter is coated with the EDM 47-024 coating, which is specifically designed to ensure optimal performance in the intended wavelength range. This coating enhances the beamsplitter's ability to reflect 50% of the incoming light while transmitting the remaining 50%.

In terms of geometry, this beamsplitter is shaped as a thin lens, which not only aids in beam splitting but also allows for easy integration into various optical systems. The physical data of the beamsplitter indicates that the reflection and transmission coefficients are both 0.5, further emphasizing its balanced performance.
