47-021 12.5 mm Dia. 50:50 (R:T) N-BK7 Plate Beamsplitter; t=3mm VIS 400-700nm
The 47-021 is a high-quality beam splitter from the renowned optical components manufacturer, Edmund Optics. This beam splitter, with a diameter of 12.5 mm, is designed for use in the visible light spectrum, specifically between 400 and 700 nm.
The beam splitter is made from N-BK7, a popular optical glass due to its excellent optical properties and high Abbe number. The N-BK7 Schott material ensures high transmission and low absorption across the visible spectrum. The beam splitter has a thickness of 3mm, providing robustness and stability.
The coating on the front surface of the beam splitter is EDM 47-021. This coating is designed to provide a 50:50 split between reflection and transmission, ensuring equal distribution of light. This makes the 47-021 ideal for applications that require balanced light distribution, such as interferometry, beam combining, and spatial light modulation.
The beam splitter is shaped as a thin lens, allowing for easy integration into optical systems. The physical data of the beam splitter indicates a reflection of 0.5 and a transmission of 0.5, further confirming the 50:50 split.
