48-198 50 mm Dia. 30:70 (R:T) UVFS UV Plate Beamsplitter; t=4mm 250-450nm

The 48-198 is a 50 mm diameter UV Plate Beamsplitter, designed for use in the ultraviolet spectrum, specifically between 250-450nm. This beamsplitter is sourced from Edmund Optics, a renowned vendor in the optical industry, and is part of their extensive catalog of optical elements.

The beamsplitter is of the Thin BS type, featuring a Thin Lens shape, which is designed to minimize optical aberrations and distortions. The beamsplitter has a diameter of 50mm and a thickness of 4mm, making it suitable for a wide range of optical applications.

The beamsplitter's coating is a crucial aspect of its functionality. The front surface of the beamsplitter is coated with EDM 65-922, a coating specifically designed to optimize performance in the UV spectrum. This coating ensures a balanced reflection and transmission of light, with the beamsplitter reflecting 30% and transmitting 70% of the incident light at the specified wavelength of 355nm.

The beamsplitter's information page on the vendor's website provides a valid link, indicating that the product is currently in stock. This beamsplitter is a reliable and efficient choice for applications that require a UV Plate Beamsplitter, particularly those operating in the 250-450nm range.
