67-535 20.0mm Dia. x 40.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex Lens, type of spherical lens, with a circular base shape, sourced from the reputable vendor Edmund Optics. The lens boasts a 20.0mm diameter and a 40.0mm focal length, making it suitable for a wide range of applications.
The lens is made from n-sf11 Schott, a high-quality material known for its excellent optical properties. The geometry of the lens includes a thickness edge of 1.26mm and a thickness center of 4mm, with an effective focal length (EFL) of 25mm. The radius of curvature (R1) is 19.62mm, and the back focal length (BFL) is 22.76mm.
The lens is coated with the EDM NIR-II STD curve on both the front and back surfaces, enhancing its performance in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm. This coating ensures optimal transmission and minimal reflection, making it ideal for NIR applications.
