BCP41R 25 x 36 mm UVFS Beamsplitter Compensator Plate; 45° AOI AR Coating: 250-450nm; t=1 mm

The BCP41R is a rectangular beamsplitter compensator plate, measuring 25 x 36 mm with a thickness of 1 mm, manufactured by Thorlabs. This beamsplitter is designed for use with a 45° angle of incidence (AOI) and features an anti-reflection (AR) coating suitable for wavelengths between 250-450nm.

The BCP41R is made from Calcium Fluoride (CaF2), a material with a high damage threshold and excellent transmission properties in the ultraviolet, visible, and near-infrared spectral regions. This makes it an ideal choice for applications that require high-performance beamsplitting capabilities in the UV range.

The AR coating on both the front and back surfaces of the BCP41R is designed to reduce reflection and increase transmission, thereby enhancing the overall efficiency of the optical system. This coating is specifically tailored for use with wavelengths between 250-450nm, making it suitable for a wide range of UV applications.

In terms of geometry, the BCP41R features a thin lens shape, which is designed to minimize optical aberrations and ensure optimal performance. This beamsplitter is part of Thorlabs' extensive catalog of optical elements, which includes a wide range of other beamsplitters, mirrors, lenses, and other optical components.
