BCP43R 25 x 36 mm UVFS Beamsplitter Compensator Plate; 45° AOI AR Coating: 400-700nm; t=1 mm

The BCP43R is a high-quality beamsplitter compensator plate designed and manufactured by Thorlabs. This rectangular beamsplitter, measuring 25 x 36 mm, is designed with a thin lens shape and a thickness of 1 mm, making it a versatile option for various optical applications.

The beamsplitter is made from CAF2 (Calcium Fluoride) material, which is known for its excellent optical properties, including high transparency and damage threshold. This specific model is coated with a 45° Angle of Incidence (AOI) Anti-Reflective (AR) coating, optimized for the wavelength range of 400-700nm. This coating ensures high transmission and low reflection, enhancing the performance of the beamsplitter in its intended application.

The BCP43R is part of Thorlabs' extensive catalog of optical elements, which 3DOptix integrates into its advanced optical simulation software. This beamsplitter compensator plate is available for purchase directly from Thorlabs, as indicated by the "Valid - in stock" status in the item data.
