84-491 50 mm Dia. 70:30 (R:T) UVFS UV Plate Beamsplitter; t=4mm 250-450nm

The 84-491 50 mm Dia. 70:30 (R:T) UVFS UV Plate Beamsplitter is a high-quality optical component sourced from Edmund Optics. This beamsplitter, with a diameter of 50 mm and a thickness of 4 mm, is designed for use in the ultraviolet (UV) spectrum, specifically between 250-450nm.

The beamsplitter is a Thin BS type, which means it is designed to minimize optical path length differences. This is particularly useful in applications where precise alignment and minimal distortion are critical. The beamsplitter's geometry is circular, making it suitable for a wide range of optical systems.

The UVFS material ID indicates that this beamsplitter is made from a unique UV-transmitting fused silica. This material is known for its excellent transmission properties in the UV range, making it ideal for UV applications.

The coating on the front surface of the beamsplitter is EDm 84-483. This coating is designed to enhance the beamsplitter's performance in the UV range, ensuring high reflectivity and transmission where it matters most.

The beamsplitter's physical data indicates that it has a reflection of 0.7 and a transmission of 0.3 at the base wavelength of 355nm. This ratio of reflection to transmission is often referred to as 70:30 (R:T).
