67-624 12mm Dia. x 24mm FL; NIR II Coated; DCX N-K5 Lens NIR II 750-1550nm
The 67-624 is a high-performance spherical lens, boasting a 12mm diameter and a 24mm focal length, specifically designed for use in the near-infrared (NIR) spectrum. This lens is sourced from the renowned optical vendor, Edmund Optics, and is currently in stock.
The lens is crafted from the high-quality material N-K5, a type of glass produced by Schott, ensuring durability and clarity. It features a standard NIR-II coating on both the front and back surfaces, which enhances its performance in the 750-1550nm wavelength range.
The geometry of the lens is meticulously designed, with a 2.5mm edge thickness and a 4mm center thickness. The lens's effective focal length (EFL) is 24mm, and it has a back focal length (BFL) of 22.65mm. The first and second radii of curvature are 24.4mm and -24.4mm, respectively.
This lens is a Convex-Convex (CC) type, with a circular base shape. It does not have an inner or outer radius, indicating a uniform curvature throughout. The lens's shape is spherical, which is a common choice for its ability to focus light evenly and efficiently.
