BSX04 Dia:0.5in 90:10 (R:T) UVFS Plate Beamsplitter; Coating: 400-700nm; t=3 mm

The BSX04 is a high-quality beam splitter from Thorlabs, designed with a circular geometry and a diameter of 0.5 inches (12.7 mm). It features a thickness of 3 mm, making it a robust and stable optical component. This beam splitter is categorized as a thin BS, which refers to its specific design and construction.

The BSX04 is made from UVFS material, identified as MAL-1965 in the material database. It is designed to operate at a wavelength of 633 nm, making it suitable for a wide range of optical applications. The beam splitter's coating is a crucial aspect of its functionality. The front surface of the BSX04 is coated with tho 9010uvbs400700, a coating specifically designed for this model to ensure optimal performance within the wavelength range of 400-700 nm.

In terms of its optical properties, the BSX04 offers a beam splitting ratio of 90:10 for reflection to transmission. This means that 90% of the incident light is reflected, while 10% is transmitted. This ratio is crucial in determining how the beam splitter will divide the incoming light, making it a critical factor in the selection process.

The BSX04 is currently in stock and available for immediate purchase. For more detailed information, please refer to the vendor's website at https://www.thorlabs.com/thorproduct.cfm?partnumber=BSX04.
