20BC17MB.2 50.8 x 50.8mm N-BK7 Broadband Non-Polarizing Cube Beamsplitter; t=50.8mm 700-1100nm

The 20BC17MB.2 is a high-quality broadband non-polarizing cube beamsplitter, sourced from the renowned optical component manufacturer, MKS/Newport. This beamsplitter is designed for use in a wide range of applications, particularly where broadband light splitting is required.

The beamsplitter features a robust N-BK7 Schott substrate, a popular material for its excellent optical properties and versatility. The geometry of the beamsplitter is defined by a width, height, and thickness of 50.8mm each, making it suitable for applications requiring a substantial optical path.

The beamsplitter's coating is a crucial aspect of its functionality. The front, back, left, and right surfaces are coated with an ideal broadband anti-reflective (AR) coating, ensuring minimal loss of light due to reflection. The hypotenuse 1 surface is coated with a New MB.2 coating, while the hypotenuse 2 surface is coated with an ideal broadband AR coating. This specific coating configuration enhances the beamsplitter's performance across the 700-1100nm wavelength range.

The beamsplitter's physical data indicates a reflection of 0.5 and a transmission of 0.5, demonstrating its balanced light splitting capability. The beamsplitter's shape is that of a cube, a common and convenient form factor for many optical systems.
