The BS043 is a non-polarizing beamsplitter cube, designed and manufactured by Thorlabs. This beamsplitter cube is a crucial component in various optical systems, facilitating the division of incident light into reflected and transmitted components. The cube features a side length of 20 mm, making it compatible with a wide range of optical setups.
The beamsplitter's coating, tho cbs bbar400-700, is applied to all surfaces, ensuring consistent performance across various wavelengths. The coating is designed to operate within the 400-700 nm range, making it suitable for a broad spectrum of applications. The beamsplitter's reflection and transmission coefficients are 0.1 and 0.9, respectively, at the central wavelength of 633 nm.
The BS043 is made from n-bk7 Schott glass, a material known for its excellent optical properties. This beamsplitter cube is available from Thorlabs, and the link provided leads to a page where you can find more information about the product, including its current availability.
