BSW511R 25 x 36 mm 50:50 (R:T) CaF2 Plate Beamsplitter; Coating: 1-6 µm; t=1 mm
The BSW511R is a beam splitter offered by Thorlabs, designed with a rectangular base shape and a thin lens configuration. This beam splitter boasts a size of 25 x 36 mm and a thickness of 1 mm, making it a sleek and compact solution for various optical applications.
The beam splitter's primary material is Calcium Fluoride (CaF2), identified as "caf2 mal-1963" in the Material ID. This material is known for its excellent transparency in the ultraviolet, visible, and near-infrared regions, making the BSW511R suitable for a wide range of wavelengths. In this particular instance, the wavelength specified is 633 nm.
The BSW511R features a 50:50 beam splitting ratio, meaning it evenly divides the incoming light into reflected and transmitted components. The coating on the front surface is "tho 50caf2bs10006000", which is designed to handle wavelengths from 1 to 6 µm. This coating ensures optimal performance and durability for the beam splitter.
