68-547 10 x 10mm 30:70 (R:T) N-BK7 Standard Cube Beamsplitter; t=10mm 400-700nm

The 68-547 is a standard cube beamsplitter offered by Edmund Optics, designed for use in the 400-700nm wavelength range. This beamsplitter features a 10mm x 10mm geometry, with a thickness of 10mm and a cube side also measuring 10mm, providing a robust and compact design.

The beamsplitter's primary function is to divide incoming light into reflected and transmitted components. The 68-547 model offers a 30:70 (R:T) split, meaning that approximately 30% of the incident light is reflected, while the remaining 70% is transmitted. This ratio is consistent across the specified wavelength range, ensuring predictable and reliable performance.

The beamsplitter is constructed from N-BK7, a high-quality glass material manufactured by Schott. This material is known for its excellent optical properties, including high transparency and low dispersion, making it a popular choice for a wide range of optical applications.

The 68-547 beamsplitter features a standard coating on all surfaces. The front, back, left, and right surfaces are coated with EDM MGF2 STD CURVE, while the hypotenuse 1 surface is coated with EDM VIS R30 T70. These coatings are designed to enhance the beamsplitter's performance and durability, ensuring optimal operation and longevity.
