67-546 25.0mm Dia. x 50.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm

The 67-546 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 50.0mm, making it a versatile choice for various optical applications.

The lens is crafted from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material ensures the lens delivers sharp and clear images, making it suitable for use in imaging systems, beam shaping, and other applications where high-quality optical performance is required.

The 67-546 features a plano-convex geometry, meaning one side of the lens is flat (plano), while the other side is curved (convex). This design allows for efficient light collection and focusing, making the lens ideal for use in systems where light needs to be concentrated onto a small area.

The lens is coated with Edmund Optics' NIR-II standard curve coating 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. It improves the lens's transmission, reduces reflection, and increases the overall system's efficiency in the NIR range.

In terms of dimensions, the lens has a thickness of 1.73mm at the edge and 8.06mm at the center. The effective focal length (EFL) is 30mm, and the radius of curvature (R1) is 15.5mm. The back focal length (BFL) is 24.69mm.
