The 65-926 30 mm Dia. 30:70 (R:T) UVFS UV Plate Beamsplitter is a high-quality optical component sourced from Edmund Optics. This beamsplitter, with a diameter of 30 mm and a thickness of 3 mm, is designed for use in the ultraviolet (UV) range, specifically between 250 and 450 nm.
The beamsplitter is of the Thin BS subtype, which means it is designed to minimize optical path length differences. This makes it ideal for applications where precise alignment and minimal distortion are crucial. The base shape is circular, which further enhances its versatility in various 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 suitable for UV applications.
The coating on the front surface of the beamsplitter is EDm 65-922. This coating is specifically designed to enhance the beamsplitter's performance in the UV range. The physical data indicates a reflection of 0.3 and transmission of 0.7 for the beamsplitter, which is typical for this type of optical component.
