45-913 9mm Dia. x -9 FL; VIS-NIR Coated; Plano-Concave Lens 400-1000nm
The 45-913 is a 9mm diameter Plano-Concave Spherical Lens, offering a focal length of -9mm, making it suitable for applications requiring negative focal lengths. This lens is sourced from Edmund Optics, a reputable vendor known for its high-quality optical components.
The lens is constructed from n-sf11 Schott, a high-index glass material that offers excellent optical performance. It has a diameter of 9mm and a thickness that varies from 3.63mm at the edge to 2.25mm at the center. The lens's base shape is circular, and it features an inner radius of 0mm and an outer radius of 0mm.
The 45-913 is coated with edm visnir0sp2002000, a VIS-NIR coating that enhances its performance in the visible and near-infrared spectrum (400-1000nm). This coating provides improved transmission and reduces reflection, making it ideal for applications that require high light transmission and minimal loss due to reflection.
The lens's geometry, including its radius of curvature (r1) of -7.07mm and back focal length (bfl) of -10.21mm, further enhances its optical performance. The lens's effective focal length (efl) is -9mm, which is a critical parameter for lens selection.
