NPCH-15-15500 15 x 15 mm 50:50 (R:T) N-BK7 Non-polarizing Cube Beamsplitter; t=15mm 1550nm

The NPCH-15-15500 is a non-polarizing cube beamsplitter offered by OptoSigma, designed for use in optical systems operating at a wavelength of 1550nm. This beamsplitter features a 15 x 15 mm cross-section, making it suitable for a wide range of applications.

The beamsplitter is designed with N-BK7 Schott glass, a popular choice for its excellent optical properties and versatility. The beamsplitter has a 50:50 reflection-to-transmission ratio, ensuring equal distribution of light between the reflected and transmitted paths. This makes it an ideal choice for applications requiring balanced light distribution.

The NPCH-15-15500 features broadband anti-reflection coatings on all surfaces, including the hypotenuse faces. This coating is specifically optimized for the 1550nm wavelength, reducing unwanted reflections and increasing the overall efficiency of the beamsplitter. The coating also helps to minimize scattering, improving the quality of the transmitted and reflected beams.

The beamsplitter is designed in a cube shape, providing robustness and ease of integration into optical systems. The cube shape also ensures a consistent beam path, making it easier to align and maintain the optical system.
