12.7 mm Diameter 33:67 (R:T) Nitrocellulose Pellicle Beamsplitter with 0.002mm Thickness and 400-700nm Wavelength Range

This beamsplitter, offered by Edmund Optics, is a circular-shaped optical element designed for splitting and reflecting incident light beams. With a clear aperture of 12.7 mm, it is suitable for a wide range of applications. The beamsplitter features a thin pellicle design, with a thickness of just 0.002mm, making it highly efficient and minimizing unwanted optical aberrations.

The beamsplitter's coating, edm bs 33r-67t, is specifically designed for a 33:67 (R:T) reflectance-to-transmission ratio. This means that approximately 33% of the incident light will be reflected, while the remaining 67% will be transmitted. This ratio is maintained across the beamsplitter's operational wavelength range of 400-700nm, making it ideal for applications that require broadband light splitting.

The beamsplitter's material ID, uvfs mal- 1965, suggests that it is made from a high-quality, UV-grade fused silica. This material is known for its excellent optical properties, including high transparency, low autofluorescence, and excellent chemical resistance.
