NPCH-15-5145 15 x 15 mm 50:50 (R:T) N-BK7 Non-polarizing Cube Beamsplitter; t=15mm 514.5nm

The NPCH-15-5145 is a non-polarizing cube beamsplitter offered by OptoSigma, designed for use in various optical systems. This beamsplitter is characterized by its 15 x 15 mm geometry, making it suitable for applications requiring a compact, cube-shaped optical element.

The beamsplitter features a 50:50 reflection-to-transmission ratio, meaning it evenly divides incoming light, reflecting 50% and transmitting the remaining 50%. This characteristic is particularly useful in applications where balanced light division is required, such as in interferometry or beam combining setups.

The NPCH-15-5145 is made from N-BK7 glass, a popular material in optical systems due to its excellent optical properties and high damage threshold. The beamsplitter's coating further enhances its performance, with ideal broadband anti-reflection coatings applied to all surfaces, minimizing unwanted reflections and ensuring optimal light transmission.

The beamsplitter's wavelength is centered at 514.5 nm, making it suitable for applications using green light sources, such as argon-ion or frequency-doubled Nd:YAG lasers. Its cube shape, coupled with its high-quality coating, makes it a reliable and versatile component in various optical systems.
