BSW505 Dia:0.5in 50:50 (R:T) CaF2 Plate Beamsplitter; Coating: 2-8 µm; t=3 mm
The BSW505 is a beam splitter offered by Thorlabs, a leading vendor in the optical industry. This particular model features a circular geometry with a diameter of 0.5 inches (12.7 mm) and a thickness of 3 mm. The material of choice for this beam splitter is Calcium Fluoride (CaF2), identified in the item data as "caf2 mal-1963".
The BSW505 is designed to operate at a wavelength of 633 nm, making it suitable for a wide range of applications. The coating on the front surface is "tho 50caf2bs20008000", which is a non-reflective coating that ensures a 50:50 split between reflection and transmission. This coating is effective for wavelengths between 2 and 8 µm.
The physical data of this beam splitter indicates a reflection of 0.5 and a transmission of 0.5, which is consistent with its design as a 50:50 beam splitter. This means that approximately half of the incident light will be reflected, while the other half will be transmitted through the beam splitter.
