48-040 12mm Dia. x 12mm FL; UV-AR Coated; UV Double-Convex Lens UV-AR 250-425nm
This is a 12mm diameter, 12mm focal length UV-AR coated double-convex lens, sourced from the reputable vendor, Edmund Optics. The lens is designed for use within the UV spectrum, specifically between 250 and 425nm, making it ideal for applications such as UV imaging, spectroscopy, and other UV-based optical systems.
The lens is spherical in shape, with a base shape of a circle. It features a front radius (R1) of 9.75mm and a back radius (R2) of -9.75mm, indicating its double-convex design. The lens has an effective focal length (EFL) of 12mm, a back focal length (BFL) of 9.25mm, and a thickness at the edge of 2.96mm, which increases to 7.09mm at the center.
The lens is made from fused silica, identified as mal-1965 in the material ID. This material is known for its excellent transparency in the UV range, low auto-fluorescence, and high resistance to thermal shock and chemical etching.
The lens is coated with a UV-AR coating on both the front and back surfaces. This coating is designed to provide high transmission in the UV range while also offering protection against UV radiation. The coating follows the standard curve as defined by Edmund Optics.
