63-830 12mm Dia. x 24mm FL; VIS-NIR Coated; UV Double-Convex Lens VIS-NIR 400-1000nm

This 12mm diameter by 24mm focal length double-convex lens, sourced from Edmund Optics, is a versatile optical component designed for use in the visible to near-infrared spectrum (400-1000nm). Its spherical design, with a base shape of a circle, ensures efficient light transmission and minimal distortion.

The lens features a front and back coating of edm visnir0sp2002000, a proprietary coating developed by Edmund Optics, which enhances its performance in the VIS-NIR range. This coating reduces surface reflections, increasing the amount of light transmitted through the lens, and improving overall image quality.

The geometry of the lens includes an inner radius of 0 and an outer radius of 0, suggesting a symmetrical design. The edge thickness measures 1.39, while the center thickness is 3.1, providing a balanced structure that minimizes optical aberrations. The effective focal length (EFL) is 24, and the back focal length (BFL) is 22.92, offering a long focal length that can be beneficial in various applications.

This lens is made from fused sil mal-1965, a material known for its excellent optical properties and durability. The wavelength of 587.6nm indicates the lens's design is optimized for the yellow-green part of the spectrum, although its VIS-NIR coating allows it to perform effectively across a broader range.
