NPCH-10-6700 10 x 10 mm 50:50 (R:T) N-BK7 Non-polarizing Cube Beamsplitter; t=10mm 670nm

The NPCH-10-6700 is a non-polarizing cube beamsplitter offered by OptoSigma, designed for use in various optical systems. This beamsplitter features a 10mm x 10mm geometry, making it suitable for applications requiring a compact, cube-shaped optical element.

The beamsplitter is designed to reflect and transmit 50% of the incident light at a wavelength of 670nm, providing a balanced split of the incoming light. This 50:50 (R:T) ratio ensures that the reflected and transmitted beams maintain equal intensities, which is crucial in many optical setups.

The NPCH-10-6700 is made from N-BK7 glass, a popular material in optical systems due to its excellent optical properties and wide transparency range. The beamsplitter's coating further enhances its performance, with ideal broadband anti-reflection coatings applied to all surfaces, minimizing unwanted reflections and improving overall transmission.

The coating on the hypotenuse faces (hypotenuse 1 and hypotenuse 2) is specifically designed for this beamsplitter. Hypotenuse 1 features an OptoSigma-specific coating (NPCH-6700), while hypotenuse 2 has an ideal broadband anti-reflection coating. These coatings contribute to the beamsplitter's high performance and reliability in various applications.
