BSW24 Dia:2in 50:50 (R:T) IR Fused Silica Plate BS; Coating: 0.9-2.6 µm; t=8 mm

The BSW24 is a high-quality beam splitter from Thorlabs, designed for use in the infrared spectrum with a wavelength of 633 nm. This beam splitter is circular in shape, with a diameter of 50.8 mm and a thickness of 8 mm, making it suitable for a wide range of optical applications.

The BSW24 features a 50:50 beam splitting ratio, meaning it evenly divides incoming light beams into reflected and transmitted components. This is particularly useful in applications where equal distribution of light is required. The beam splitter is made of fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock.

The front surface of the BSW24 is coated with a thin film coating, specifically the THo 50 UV BS 9002600 coating. This coating enhances the beam splitter's performance in the infrared region, ensuring optimal operation within its specified wavelength range of 0.9 to 2.6 µm.

In terms of physical data, the BSW24 has a reflection of 0.5 for the beam splitter, and a transmission of 0.5, again reflecting its 50:50 beam splitting ratio. This beam splitter is available for purchase directly from Thorlabs, and the company's website indicates that it is currently in stock.
