47-364 12mm Dia. x 72mm FL; VIS 0deg Coated; Double-Convex Lens VIS 0deg 425-675nm
The 47-364 is a high-quality Double-Convex Lens, sourced from the renowned optical components manufacturer, Edmund Optics. This lens boasts a 12mm diameter and a focal length of 72mm, making it suitable for a wide range of applications that require precise optical focusing.
The lens is crafted from Schott's n-BK7 glass, a material known for its excellent optical properties, including a high Abbe number and low dispersion. This ensures minimal chromatic aberration, a critical factor in high-resolution imaging and metrology applications.
The 47-364 features a standard coating on both the front and back surfaces, specifically the EDM VIS-0 std curve coating. This coating is designed to enhance the lens's transmission in the visible spectrum, between 425 and 675nm. It also provides protection against environmental factors, such as dust and moisture, thereby extending the lens's lifespan.
The lens's geometry is another notable feature. It has an edge thickness of 2.31mm and a center thickness of 2.8mm, providing robustness and resistance to deformation. The inner and outer radii are 0mm, indicating a uniform curvature across the lens surface.
