The 20BC17MB.3 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 the 1100-1600nm wavelength range, making it suitable for a wide array of applications in the optical industry.
The beamsplitter features a robust N-BK7 Schott substrate, a popular choice in the industry due to its excellent optical properties and versatility. The geometry of the beamsplitter is defined by a width, height, and thickness of 50.8mm each, providing a substantial surface area for efficient light manipulation.
The beamsplitter's coating is another notable feature. Both the front and back surfaces are coated with an ideal broadband anti-reflective (AR) coating, ensuring minimal loss of light due to reflection. The left and right surfaces also boast the same ideal broadband AR coating, further enhancing the beamsplitter's performance.
The hypotenuse surfaces of the beamsplitter are treated differently. Hypotenuse 1 is coated with a New MB.3 coating, while Hypotenuse 2 is coated with the ideal broadband AR coating. This specific coating configuration enhances the beamsplitter's performance in its designated wavelength range.
The beamsplitter's physical data indicates a reflection of 0.5 and a transmission of 0.5 for the base shape volume. This 50:50 split is typical for non-polarizing beamsplitters and is crucial for applications requiring equal distribution of light.
