45-870 9mm Dia. x 36mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 45-870 is a high-quality double-convex lens, boasting a 9mm diameter and a 36mm focal length. This lens is sourced from the reputable vendor, Edmund Optics, and is available in stock for immediate use. The lens is designed with a spherical shape, featuring a base shape of a circle, making it a versatile choice for various optical applications.
The lens is constructed from the material n-bk7 schott, a popular choice due to its excellent optical properties and durability. The geometry of the lens is well-defined, with a thickness of 2mm at the edge and 2.55mm at the center. The effective focal length (EFL) is 36mm, and the radii of curvature are 36.77mm for the first surface and -36.77mm for the second surface. The back focal length (BFL) is 35.15mm.
The 45-870 lens is coated with a VIS-NIR coating, specifically the edm visnir0sp2002000 coating, on both the front and back surfaces. This coating enhances the lens's performance in the visible to near-infrared spectrum, covering a wavelength range of 400-1000nm. This makes the lens suitable for a wide range of applications, including but not limited to, imaging, spectroscopy, and beam manipulation.
