49-843 12.7mm Dia. x 31.8mm FL; Uncoated; Plano-Convex Lens

The 49-843 is a Plano-Convex lens with a diameter of 12.7mm and a focal length of 31.8mm, making it ideal for a wide range of optical applications. This lens is sourced from the reputable vendor, Edmund Optics, and is available for purchase directly from their website.

The lens is made from the high-quality material, n-BK7 Schott, which is known for its excellent optical properties. The Plano-Convex geometry, where one side is flat and the other is curved, allows for efficient light convergence. The lens has an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature.

The lens has a thickness of 1.72mm at the edge and 3mm at the center, providing a solid structure. The back focal length (BFL) is 29.81mm, and the effective focal length (EFL) is 31.8mm, which are crucial specifications for designing optical systems.

This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While coatings can improve light transmission and reduce reflections, an uncoated lens can be beneficial in certain applications, such as when minimal reflection is required.

The lens is designed to work with a wavelength of 587.6nm, which is in the visible light spectrum. This makes it suitable for applications that involve visible light, such as imaging systems, beam shaping, and light focusing.
