47-888 20.0mm Dia. x 60.0mm FL; VIS 0deg Coated; Plano-Convex Lens VIS 0° 425-675nm
The 47-888 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 20.0mm and a focal length of 60.0mm, making it a versatile choice for various optical applications.
The lens is made from the material n-bk7 schott, a popular choice in the optical industry due to its excellent optical properties. The lens's geometry includes a thickness of 2.84mm at the edge and 4.5mm at the center, with an effective focal length (EFL) of 60.0mm. The front surface has a radius of curvature of 31.01mm, and the back focal length (BFL) is 57.03mm.
The 47-888 features a coating on both the front and back surfaces. This coating, identified as 'edm vis-0 std curve', is designed to optimize performance within the visible light spectrum, specifically between 425-675nm. This coating enhances the lens's transmission and reduces reflection, thereby improving overall system efficiency.
