BCP4510 Dia:1in UVFS Beamsplitter Compensation Plate; 45° AOI AR Coating: 700-1100nm; t=5 mm

The BCP4510 is a high-quality beamsplitter compensation plate, designed and manufactured by Thorlabs. This component is specifically engineered for use in optical systems that require precise beam manipulation and control. The beamsplitter features a circular geometry, with a diameter of 1 inch (25.4 mm) and a thickness of 5 mm, making it suitable for a wide range of applications.

The BCP4510 boasts a unique coating, referred to as "tho bcp45" on both the front and back surfaces. This coating is designed to provide anti-reflective properties, optimized for a wavelength of 633 nm. The coating ensures minimal loss of light due to reflection, thereby enhancing the overall efficiency of the optical system.

One of the standout features of the BCP4510 is its 45° angle of incidence (AOI) with an AR coating suitable for the wavelength range of 700-1100 nm. This specific AOI and coating combination ensure optimal performance when the beamsplitter is used at a 45-degree angle, which is a common configuration in many optical systems.

The BCP4510 is made from CAF2 (Calcium Fluoride) material, identified by the Mal-1963 material ID. This material is known for its excellent optical properties, making it an ideal choice for beamsplitter compensation plates.
