47-122 20 x 20mm 50:50 (R:T) N-BK7 Broadband Non-Polarizing Cube Beamsplitter; t=20mm VIS 430-670nm

The 47-122 is a 20mm cube beamsplitter, designed and manufactured by Edmund Optics, a leading provider of optical components. This beamsplitter is a non-polarizing type, meaning it splits incident light without regard to its polarization state. It features a 50:50 (R:T) split ratio, indicating that it reflects 50% of the incident light and transmits the remaining 50%.

The beamsplitter is constructed from N-BK7 glass, a popular choice due to its excellent optical properties and broadband transmission characteristics. The glass is Schott-manufactured, ensuring high quality and consistency. The beamsplitter's dimensions are 20mm in width, thickness, and cube side, making it suitable for a wide range of optical applications.

The coating on this beamsplitter is a crucial component. Both the front and back surfaces are coated with an ideal broadband anti-reflective (AR) coating, reducing unwanted reflections and improving transmission. The left and right surfaces also feature the same ideal broadband AR coating. The hypotenuse faces 1 and 2 are coated with EDM 47-007 and ideal broadband AR, respectively, further enhancing the beamsplitter's performance.

This beamsplitter operates within the visible spectrum, specifically at a wavelength of 587.6nm. Its base shape is a volume, and its shape is that of a cube, making it a versatile and compact optical component. The beamsplitter's weblink is valid and indicates that it is currently in stock, ensuring quick and easy acquisition for your optical needs.
