89-118 3mm Dia. x 3mm FL; VIS-EXT Coated; Double-Convex Lens VIS-EXT 350-700nm
This is a 3mm diameter, double-convex lens, featuring a focal length of 3mm, sourced from Edmund Optics. The lens is made from n-SF5 Schott material, a high-index glass with excellent transparency in the visible spectrum. The lens has a front and back coating of EDM VIS EXT, designed to enhance transmission in the visible light range of 350-700nm.
The lens geometry includes an edge thickness of 1.64mm and a center thickness of 2.3mm. The front and back radii are 3.5mm and -3.5mm respectively, resulting in a back focal length of 2.21mm. The lens has a spherical shape, and the inner and outer radii are both 0mm.
This lens is ideal for applications that require a compact, high-performance optical element with a wide range of visibility. The EDM VIS EXT coating ensures high transmission and low reflection, making it suitable for imaging and illumination systems. The lens's small form factor and double-convex design make it an excellent choice for applications where space is limited.
