This 12mm diameter by 40mm focal length plano-convex lens, sourced from Edmund Optics, is a versatile optical component designed for use within the visible light spectrum. Its plano-convex geometry, featuring a flat front surface and a curved back surface, allows for efficient light transmission and focusing.
The lens is constructed from fused silica (mal-1965), a material known for its excellent optical properties, including high transparency and resistance to thermal shock. The 0° angle of incidence coating on both the front and back surfaces enhances the lens's light transmission capabilities, particularly within the visible light spectrum (425-675nm).
The lens's geometry is meticulously designed, with a 2.12mm edge thickness and a 3.13mm center thickness. The 18.34mm radius of curvature of the back surface contributes to a 37.85mm back focal length, making this lens suitable for a variety of optical applications.
Please note that the lens does not have any coatings on its inner or outer radii, and its shape is strictly spherical. For more information, including pricing and availability, please refer to the provided weblink, which is currently valid and indicates the lens is in stock.
