49-842 12.7mm Dia. x 25.4mm FL; Uncoated; Plano-Convex Lens
The 49-842 is a Plano-Convex lens with a diameter of 12.7mm and a focal length of 25.4mm. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components. The lens is uncoated, which means it does not have any additional layers to protect or enhance its optical properties.
The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens's geometry includes a thickness of 1.36mm at the edge and 3mm at the center. The inner and outer radii are both 0, indicating a flat surface on one side and a curved surface on the other.
The lens's effective focal length (EFL) is 25.4mm, and its back focal length (BFL) is 23.43mm. The radius of curvature (R1) is 13.13mm. These parameters are crucial in determining how the lens will interact with light and how it can be used in various optical systems.
The lens is designed to work with light of a wavelength of 587.6nm. This wavelength falls within the visible light spectrum, making this lens suitable for applications that involve visible light.
