BSW501 Dia:0.5in 50:50 (R:T) CaF2 Plate Beamsplitter; Coating: 1-6 µm; t=3 mm

The BSW501 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 BSW501 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 of the beam splitter is "tho 50caf2bs10006000", which is a 50:50 beam splitter coating, meaning it reflects 50% of the incident light and transmits the remaining 50%. This coating is designed to handle a broad spectral range from 1 to 6 µm.

The beam splitter's physical data indicates that the reflection and transmission coefficients are both 0.5, which is consistent with the 50:50 beam splitting ratio. This makes the BSW501 an ideal choice for applications requiring equal division of optical power.
