49-004 50 x 50mm 50:50 (R:T) N-BK7 Broadband Non-Polarizing Cube Beamsplitter; t=50mm VIS 430-670nm

The 49-004 is a 50mm x 50mm 50:50 (R:T) N-BK7 Broadband Non-Polarizing Cube Beamsplitter, sourced from the renowned optical components vendor, Edmund Optics. This beamsplitter is designed for use in the visible spectrum, specifically between 430nm and 670nm.

The beamsplitter is a cube-shaped optical element, with each side measuring 50mm. It features a broadband anti-reflective (AR) coating on all surfaces, including the front, back, left, right, and two hypotenuse faces. This coating ensures high transmission and low reflection across the entire spectral range, making it ideal for a wide range of applications.

The beamsplitter's physical data indicates a 50:50 reflection-to-transmission ratio. This means that approximately half of the incident light will be reflected, while the other half will be transmitted. This characteristic makes it a versatile tool for applications that require the splitting of light beams.

The beamsplitter is made from N-BK7 glass, a high-quality borosilicate crown glass known for its excellent optical properties. This material ensures high transmittance, low dispersion, and excellent homogeneity, making it a popular choice for various optical applications.
