HO-MCBS-B-20 20 x 20mm 50:50 (R:T) N-BK7 Metallic Cube Beamsplitter; t=20mm 400-700nm

The HO-MCBS-B-20 is a high-quality beamsplitter cube designed for use in optical systems where beam splitting is required. This beamsplitter is sourced from Holmarc Opto-Mechatronics, a renowned vendor known for their precision optical components.

The beamsplitter features a 20 x 20mm square cross-section, providing a substantial area for beam splitting. The beamsplitter is designed to operate with a 50:50 split ratio for both reflection and transmission, making it ideal for applications where equal distribution of light is necessary.

The beamsplitter is constructed from N-BK7 Schott glass, a material known for its excellent optical properties and high damage threshold. This material ensures high-fidelity beam splitting across the visible spectrum, with a specific wavelength of 588nm.

The beamsplitter's coating is another notable feature. Both the front and back surfaces are coated with a hol bbbar 0 aoi coating, while the left and right surfaces are also coated with the same. The hypotenuse faces are coated with hol mcbs5040070045 and hol bbbar 0 aoi coatings, respectively. These coatings are designed to optimize the beamsplitter's performance, ensuring minimal loss and high-quality beam splitting.

In terms of geometry, the beamsplitter is a cube, with each side measuring 20mm. This cube shape ensures robustness and ease of integration into optical systems. The beamsplitter's shape is classified as a BS Cube, further emphasizing its purpose and functionality.
