NPCH-10-5145 10 x 10 mm 50:50 (R:T) N-BK7 Non-polarizing Cube Beamsplitter; t=10mm 514.5nm

OptoSigma's NPCH-10-5145 is a non-polarizing cube beamsplitter, designed for use in a variety of optical systems. This beamsplitter is a 10 x 10 mm cube, with each face measuring 10 mm, making it suitable for applications where a compact, robust beamsplitter is required.

The beamsplitter has a 50:50 reflection to transmission ratio, meaning it reflects 50% of the incident light and transmits the remaining 50%. This makes it ideal for applications where equal distribution of light is necessary. The beamsplitter is designed to operate at a wavelength of 514.5 nm, a common wavelength used in laser systems.

The NPCH-10-5145 is made from N-BK7 glass, a high-quality borosilicate glass known for its excellent optical properties. This glass is Schott's standard glass and is widely used in the optical industry due to its excellent transmission characteristics and low autofluorescence.

The beamsplitter features broadband anti-reflection coatings on all surfaces, including the hypotenuse faces. This coating is designed to reduce surface reflections, improving the efficiency of the beamsplitter and reducing unwanted stray light. The hypotenuse faces are coated with an Opt NPCH-5145 coating, specifically designed for this beamsplitter.
