39-501 152.4 mm Dia. 50:50 (R:T) Nitrocellulose Pellicle Beamsplitter; t=0.002mm 632.8nm

This product is a 152.4 mm diameter, thin beam splitter offered by Edmund Optics. It features a 50:50 reflection-to-transmission ratio, making it ideal for applications that require equal distribution of light between the reflected and transmitted paths. The beamsplitter is constructed from nitrocellulose, a material known for its excellent optical properties and durability.

The beamsplitter has a thickness of 0.002 mm, which is designed to minimize dispersion and optical aberrations. It is coated with a proprietary edm bs 50r-50t coating on the front surface, enhancing its performance at the specified wavelength of 632.8 nm. This coating ensures high reflectivity and transmissivity, contributing to the overall efficiency of the optical system.

The beamsplitter's geometry is that of a thin lens, which further aids in reducing optical aberrations. Its circular shape provides a clear aperture, allowing for a wide range of applications. The physical data indicates that the beamsplitter has a reflection of 0.5 and a transmission of 0.5 at the specified wavelength, ensuring balanced light distribution.
