49-840 12.7mm Dia. x 15.0mm FL; Uncoated; Plano-Convex Lens
The 49-840 is a Plano-Convex lens with a diameter of 12.7mm and a focal length of 15.0mm, sourced from the renowned optical vendor, Edmund Optics. This lens is uncoated, which means it does not have any additional layers to enhance light transmission or protect the surface.
The lens's geometry is characterized by its base shape being circular, with a thickness at the edge of 1.94mm and a center thickness of 5.25mm. The effective focal length (EFL) is 15mm, and the radius of curvature (R1) is 7.75mm. The back focal length (BFL) is 11.53mm, and both the inner and outer radii are 0mm.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The wavelength for this lens is 587.6nm. The lens's shape is spherical, a common type of lens surface used to focus or disperse light.
This lens is a great option for those looking for a basic, high-quality optical component for their setup. However, please note that the lack of coating may make it more susceptible to environmental factors and may not perform as well in high-intensity light applications.
