NPCH-20-6328 20 x 20 mm 50:50 (R:T) N-BK7 Non-polarizing Cube Beamsplitter; t=20mm 632.8nm

The NPCH-20-6328 is a non-polarizing cube beamsplitter offered by OptoSigma, designed for use with a wavelength of 632.8 nm and a cube dimension of 20 x 20 x 20 mm. This beamsplitter is a crucial component in various optical systems, facilitating the division of an incident beam into reflected and transmitted components.

The beamsplitter boasts a 50:50 reflection-to-transmission ratio, ensuring equal distribution of the incident light. The physical data provided indicates a reflection coefficient of 0.5 and a transmission coefficient of 0.5, further emphasizing its balanced performance.

The NPCH-20-6328 is crafted from n-BK7 Schott, a high-quality optical glass renowned for its excellent transmission properties and low auto-fluorescence. This material choice ensures reliable and consistent performance across a broad spectrum of applications.

The beamsplitter's coating is another notable feature. Both the front and back surfaces are coated with ideal broadband AR, minimizing reflection and enhancing transmission. Similarly, the left and right surfaces also receive the same ideal broadband AR coating. The hypotenuse faces 1 and 2 are treated with opt npch-6328 and ideal broadband AR coatings, respectively, optimizing the beamsplitter's performance.
