BSP0125-4R2 25.4 mm Dia. 80:20 (R:T) N-BK7 Plate Beamsplitter; t=3mm 400-700nm

The BSP0125-4R2 is a high-quality beamsplitter from Union Optic, designed with a circular geometry and a diameter of 25.4 mm. This beamsplitter is 3 mm thick, making it a robust and durable option for various optical applications.

The beamsplitter is made from N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties and high damage threshold. This material is known for its low optical absorption, making it ideal for applications that require high transmission and low loss.

The BSP0125-4R2 features a uni bsp802040070045 coating on the front surface. This coating is designed to provide optimal performance in the 400-700nm wavelength range, making it suitable for a wide range of applications, including but not limited to, fluorescence microscopy, spectroscopy, and laser systems.

The beamsplitter has a reflection of 80% and a transmission of 20%, making it an 80:20 beamsplitter. This ratio is often used in applications where a significant amount of light needs to be reflected while still maintaining some transmission.
