46-687 18 x 30 mm 25:75 (R:T) Float Glass Standard Plate Beamsplitter; t=2mm 400-700nm
The 46-687 is a 2mm thick, rectangular beam splitter, measuring 18 x 30 mm, sourced from Edmund Optics. This beam splitter is designed for use in the visible spectrum, specifically between 400 and 700nm.
The beamsplitter features a 25:75 (R:T) split ratio, meaning that 25% of the incident light is reflected while 75% is transmitted. This ratio is consistent across the specified wavelength range, providing a reliable and predictable performance.
The beamsplitter is made from soda lime ru clear float glass, a material known for its high transparency and durability. The front surface of the beamsplitter is coated with edm 46-664, a coating that enhances its performance in the specified wavelength range.
The beamsplitter is shaped as a thin lens, which minimizes its thickness and weight, making it ideal for applications where space and weight are critical factors. Despite its thinness, the beamsplitter maintains excellent optical quality, ensuring minimal distortion and high transmission.
