BSW21 Dia:2in 50:50 UVFS Plate Beamsplitter; Coating: 250-450nm; t=8 mm

The BSW21 Dia:2in 50:50 UVFS Plate Beamsplitter is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of optical elements. This beamsplitter is designed with a circular geometry, featuring a diameter of 50.8 mm and a thickness of 8 mm, making it a robust and reliable choice for various optical applications.

The beamsplitter is made of UVFS material, identified as "uvfs mal- 1965" in the item data. This specific material is known for its excellent optical properties, making it suitable for use in the ultraviolet and visible spectrum regions. The BSW21 is coated with a special coating, "tho 50 uv bs 250-450" on the front and "tho uvfs uv bbar" on the back, which enhances its performance in the 250-450 nm wavelength range.

The BSW21 operates on a 50:50 basis, meaning it splits incoming light beams equally between its reflection and transmission paths. The physical data indicates a reflection rate of 0.5 and a transmission rate of 0.5, ensuring a balanced distribution of light for further optical processing.
