10B20NP.25 25.4 mm Dia. 50:50 (R:T) N-BK7 Laser Line Non-Polarizing Plate Beamsplitter; t=6.1mm 632.8nm

The 10B20NP.25 is a high-quality beamsplitter from the renowned vendor MKS/Newport. This beamsplitter is designed for use with laser lines and features a non-polarizing coating, ensuring consistent performance regardless of the polarization state of the incident light.

The beamsplitter has a circular geometry with a diameter of 25.4 mm, making it suitable for a wide range of optical systems. It features a thickness of 6.1 mm, providing robustness and stability in operation. The beamsplitter is made from N-BK7 Schott, a popular material known for its excellent optical properties and wide transmission range.

The 10B20NP.25 is designed to operate at a wavelength of 632.8 nm, making it ideal for use with helium-neon (HeNe) lasers, which are commonly used in various applications such as interferometry, holography, and alignment. The beamsplitter has a 50:50 reflection-to-transmission ratio, ensuring a balanced split of the incident light.

The front surface of the beamsplitter is coated with a new NP.25 coating, which enhances its performance and durability. This beamsplitter is available in a thin lens shape, which minimizes optical aberrations and ensures high-quality performance.
