9.0mm Dia. x 90.0mm FL VIS-EXT Coated Plano-Convex Lens from Edmund Optics
Discover the 88-661 9.0mm Dia. x 90.0mm FL VIS-EXT Coated Plano-Convex Lens, a high-quality optical component designed for a wide range of applications. This lens, available from Edmund Optics, boasts impressive specifications that make it a versatile and reliable choice for various projects.
The lens features a 9.0mm diameter and a focal length of 90.0mm, making it suitable for applications that require a long focal length. The plano-convex design, characterized by a flat front surface and a curved back surface, allows for efficient light transmission and minimal distortion.
The lens is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and high damage threshold. This material ensures high transmission in the visible spectrum, making it ideal for applications that require high light transmission.
The lens is coated with EDM VIS-EXT, a broadband anti-reflection coating designed for the visible spectrum (350-700nm). This coating reduces surface reflections, enhancing the lens's light transmission capabilities and improving overall system performance.
The geometry of the lens includes a thickness of 1.78mm at the edge and 2.0mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature. The back focal length (BFL) is 88.68mm, and the effective focal length (EFL) is 90mm.
