49-878 15.0mm Dia. x 18.0mm FL; Uncoated; Plano-Convex Lens
The 49-878 is a Plano-Convex lens with a diameter of 15.0mm and a focal length of 18.0mm, making it suitable for a wide range of optical applications. 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 enhance its optical properties. This can be advantageous in certain applications where the natural properties of the lens material are desired. The lens is made from n-sf5 Schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence.
The geometry of the lens is characterized by its diameter, thickness edge, and thickness center. The diameter is 15.0mm, the thickness edge is 1.4mm, and the thickness center is 4.0mm. The lens's effective focal length (EFL) is 18.0mm, and its back focal length (BFL) is 15.61mm. The radius of curvature of the first surface (R1) is 12.11mm.
The lens is designed to work with a wavelength of 587.6nm, making it suitable for applications that use this specific wavelength. Its spherical shape ensures excellent image quality and low distortion.
