BCP4310 Dia:1in UVFS Beamsplitter Compensation Plate; 45° AOI AR Coating: 400-700nm; t=5 mm

The BCP4310 is a beam splitter compensation plate, designed and manufactured by Thorlabs, a leading vendor in the field of optical elements. This component is specifically engineered for use in systems with a 45° angle of incidence (AOI), making it an ideal choice for a wide range of applications that require precise beam splitting at this angle.

The BCP4310 features a circular geometry, with a diameter of 1 inch (25.4 mm) and a thickness of 5 mm. This compact design ensures ease of integration into various optical systems, while maintaining the necessary robustness and durability. The component is made from CAF2 (Calcium Fluoride), a material with a Malus index of 1963, which contributes to its high performance and reliability.

The BCP4310 is coated with a proprietary Anti-Reflective (AR) coating, specifically designed for use in the UV-FS (Ultraviolet-Femtosecond) range, between 400 and 700 nm. This coating, denoted as 'tho bcp43' for both the front and back surfaces, significantly reduces unwanted reflections and increases transmission, thereby enhancing the overall efficiency and performance of the optical system.

The BCP4310 is available for purchase directly from Thorlabs, and as of the time of this description, it is in stock. For more detailed information, including technical specifications and purchasing options, please refer to the vendor's official product webpage linked below.
