10B20NP.31 25.4 mm Dia. 50:50 (R:T) N-BK7 Laser Line Non-Polarizing Plate Beamsplitter; t=6.1mm 1550nm

The 10B20NP.31 is a high-quality beamsplitter, specifically designed for use in laser applications. Sourced from the reputable vendor MKS/Newport, this beamsplitter boasts a circular geometry with a diameter of 25.4 mm, making it suitable for a wide range of optical systems.

The beamsplitter is constructed from N-BK7 Schott glass, a material well-known for its excellent optical properties. This includes a high refractive index and low dispersion, which are crucial for maintaining beam integrity in laser applications. The beamsplitter has a thickness of 6.1 mm, providing sufficient structural rigidity while minimizing unwanted optical effects.

The 10B20NP.31 features a non-polarizing coating (new np.31) on the front surface. This coating ensures equal transmission of both polarization states, making it ideal for applications where polarization independence is required. The beamsplitter is designed to operate at a wavelength of 1550 nm, a common wavelength for fiber optic communications and other laser applications.

The beamsplitter's physical data indicates a 50:50 (R:T) split ratio, meaning it reflects and transmits 50% of the incident light, respectively. This makes it a versatile tool for applications requiring balanced splitting of laser beams.
