The 68-545 is a standard cube beamsplitter offered by Edmund Optics, designed for use in the 400-700nm wavelength range. This beamsplitter features a 5mm x 5mm geometry, with a thickness of 5mm and a cube side length also of 5mm.
The beamsplitter has a reflection ratio of 30:70, meaning it reflects 30% of the incident light and transmits 70%. This ratio is consistent across both the front and back faces, as well as the left and right faces of the beamsplitter.
The material used for this beamsplitter is N-BK7 Schott, a popular choice in the optical industry due to its excellent optical properties and wide transmission range. The beamsplitter's coating is EDM MgF2 std curve on all faces, with the exception of the hypotenuse faces, which are coated with EDM Vis R30 T70 and EDM MgF2 std curve.
This beamsplitter is available for purchase directly from the Edmund Optics website, where it is currently in stock. For more detailed information, including technical specifications and purchasing options, please refer to the provided weblink.
