49-183 3mm Dia. x 6mm FL; VIS 0deg Coated; Double-Convex Lens VIS 0deg 425-675nm

The 49-183 is a high-quality Double-Convex Lens, sourced from the renowned optical components manufacturer, Edmund Optics. This lens, with a diameter of 3mm and a focal length of 6mm, is designed for use within the visible light spectrum, specifically between 425-675nm.

The lens is crafted from the high-grade material, n-BK7 Schott, a borosilicate glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. This ensures the lens delivers superior performance and maintains its shape and integrity even when subjected to varying temperatures.

The 49-183 features a front and back coating of edm vis-0 std curve. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving overall image quality. The coating is designed to work optimally within the visible light spectrum, making it ideal for a wide range of applications.

The lens's geometry is meticulously designed, with an inner radius of 0mm and an outer radius of 0mm. The edge thickness measures 1.41mm, while the center thickness is 1.8mm. The back focal length is 5.37mm, and the effective focal length is 6mm. This geometry ensures the lens provides a sharp, clear image, making it suitable for various optical systems.
