48-266 6mm Dia. x -12 FL; VIS 0deg Coated; Plano-Concave Lens 425-675nm
The 48-266 is a Plano-Concave Spherical Lens with a 6mm diameter, sourced from Edmund Optics. This lens is designed for use within the wavelength range of 425-675nm, making it suitable for a wide array of optical applications.
The lens features a base shape of a circle and has a thickness of 2.12mm at the edge, reducing to 1.5mm at the center. The effective focal length (EFL) is -12, and the front radius of curvature (R1) is -6.2. The back focal length (BFL) is -12.99, and both the inner and outer radii are 0. The lens is made from n-BK7 Schott material, a popular choice for its high refractive index and low dispersion.
The 48-266 comes with a standard coating on both the front and back surfaces. This coating, identified as 'edm vis-0 std curve', is designed to enhance the lens's performance within the visible light spectrum (0 degrees). The lens's coating and material composition contribute to its overall optical quality, reducing surface reflections and improving transmission.
