47-372 25mm Dia. x 150mm FL; VIS 0deg Coated; Double-Convex Lens VIS 0deg 425-675nm

The 47-372 is a high-quality Double-Convex Lens, sourced from the renowned optical component vendor, Edmund Optics. This lens, with a diameter of 25mm and a focal length of 150mm, is designed for visible light applications, specifically within the wavelength range of 425-675nm.

The lens features a double-convex geometry, characterized by two spherical surfaces that curve outwards. This design allows for a high refractive power, making it ideal for imaging applications where a high level of magnification is required. The base shape of the lens is circular, ensuring uniform light transmission and minimal distortion.

The 47-372 lens is constructed from N-BK7 Schott glass, a material well-known for its excellent optical properties. This includes a high Abbe number, low optical dispersion, and excellent homogeneity, making it a popular choice for a wide range of optical applications.

The lens is coated with the EDM VIS-0 STD curve on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and increase transmission, thereby enhancing the overall performance of the lens. The coating is specifically tailored for visible light applications, ensuring optimal performance within the lens's specified wavelength range.

In terms of dimensions, the lens has a thickness of 2.39mm at the edge and 3.4mm at the center. The effective focal length (EFL) is 150mm, while the back focal length (BFL) is 148.88mm. The inner and outer radii are 0mm, indicating a uniform curvature across the lens surface.
