351-0207-M2P 20 x 20 mm 50:50 (R:T) N-BK7 Non-Polarizing Cube Beamsplitter; t=20 mm 450-700nm

The 351-0207-M2P is a non-polarizing cube beamsplitter, designed and manufactured by EKSMA Optics, a leading global provider of optical components. This beamsplitter is a cube-shaped optical element, designed to split an incident light beam into two separate beams of equal intensity.

The beamsplitter features a 20 x 20 mm aperture, providing a substantial area for light to pass through. The geometry of the beamsplitter is such that it has a thickness (t) of 20 mm, ensuring robustness and durability.

The beamsplitter is designed to operate within the wavelength range of 450-700 nm, making it suitable for a wide range of applications, particularly those in the visible light spectrum. The reflection and transmission coefficients of the beamsplitter are both 0.5, indicating a 50:50 split of the incident light.

The beamsplitter is made from N-BK7, a high-quality borosilicate glass, known for its excellent optical properties. This material is used for both the hypotenuse faces of the beamsplitter, while the other faces are coated with an ideal broadband anti-reflective (AR) coating. This coating reduces reflection and increases transmission, enhancing the performance of the beamsplitter.

The beamsplitter is available for purchase directly from the EKSMA Optics website, where more detailed specifications and additional product information can be found.
