BSW520 Dia:2in 50:50 (R:T) CaF2 Plate Beamsplitter; Coating: 2-8 µm; t=8 mm

The BSW520 Dia:2in 50:50 (R:T) CaF2 Plate Beamsplitter is a high-quality optical component sourced from Thorlabs. This beamsplitter is designed with a calcium fluoride (CaF2) substrate, which is known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum. The beamsplitter has a diameter of 2 inches (50.8 mm) and a thickness of 8 mm, making it suitable for a wide range of optical applications.

The beamsplitter features a 50:50 reflectance to transmission ratio, meaning it splits incoming light equally between its reflection and transmission paths. This makes it ideal for applications that require balanced light distribution, such as interferometry and imaging systems. The coating on the front surface of the beamsplitter is designed to handle wavelengths between 2 and 8 µm, further expanding its range of potential uses.

The BSW520 is shaped as a thin lens, which can be beneficial in certain optical configurations. It is important to note that the beamsplitter's physical data includes a reflection of 0.5 and a transmission of 0.5, reflecting its balanced light distribution capabilities.
