BSW25 Dia:0.5in 50:50 UVFS Plate Beamsplitter; Coating: 350-1100nm; t=3.0 mm

The BSW25 Dia:0.5in 50:50 UVFS Plate Beamsplitter is a high-quality optical component sourced from Thorlabs. This beamsplitter is designed with a circular geometry, featuring a diameter of 12.7 mm and a thickness of 3.0 mm, making it a thin lens type.

The beamsplitter's primary material is UVFS, identified as "uvfs mal- 1965" in the item data. It is designed to operate at a wavelength of 633 nm, although its coating allows for a broader range of usability.

The coating on this beamsplitter is a key feature. The front side is coated with "tho 50 uv bs 3501100", a coating that is specifically designed for use in the ultraviolet range from 350 nm to 1100 nm. This coating ensures high performance and durability in a wide range of applications. The back side of the beamsplitter is coated with "tho ab bbar", a coating that is typically used to enhance the durability and performance of the optical surface.

In terms of its physical properties, the beamsplitter has a reflection rate of 0.5 and a transmission rate of 0.5 for the base shape. This 50:50 split makes it a versatile tool for various optical applications.
