NPCH-10-5320 10 x 10 mm 50:50 (R:T) N-BK7 Non-polarizing Cube Beamsplitter; t=10mm 532nm

The NPCH-10-5320 is a non-polarizing cube beamsplitter offered by OptoSigma, designed for use in various optical systems. This beamsplitter is characterized by its 10 x 10 mm geometry, making it suitable for applications requiring a compact, robust optical component.

The beamsplitter features a 50:50 reflection-to-transmission ratio, ensuring equal distribution of light between the reflected and transmitted paths. This characteristic is particularly useful in applications where balanced light distribution is required, such as interferometry or beam combining.

The NPCH-10-5320 is crafted from N-BK7 Schott glass, a material known for its excellent optical properties and broadband transmission characteristics. This ensures high-quality performance across a wide range of wavelengths, with a specific focus on the 532 nm wavelength.

The beamsplitter's coating is another notable feature. Both the front and back surfaces are coated with ideal broadband anti-reflection (AR) coatings, minimizing unwanted reflections and improving overall transmission. The hypotenuse faces also receive specialized coatings: one with an OptoSigma-specific coating (NPCH-5320) and the other with an ideal broadband AR coating.
