67-543 25.0mm Dia. x 30.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm

The 67-543 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 25.0mm and a focal length of 30.0mm, making it a compact yet powerful optical component. The lens is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility.

The lens features a plano-convex geometry, meaning one side is flat (plano) while the other side is curved (convex). The curvature of the convex side is defined by a radius of 51.68mm. This geometry, combined with the lens's dimensions, results in an effective focal length (EFL) of 100mm. The back focal length (BFL) is 97.13mm, and the lens has a thickness of 3.32mm at the edge and 4.3mm at the center.

The 67-543 lens is coated with Edmund Optics' NIR-II standard curve on both the front and back surfaces. This coating enhances the lens's performance in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm. This makes the lens ideal for applications that require high-quality imaging or light transmission in the NIR range, such as night vision, thermal imaging, or spectral analysis.
