The 89-209 is a high-quality double-convex lens, boasting a 4.5mm diameter and a focal length of 4.5mm. This lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock.
The lens is crafted from the material n-lasf44 schott, a popular choice for its optical properties. It features a front and back coating of edm yagbbar 5001100, providing superior performance within the wavelength range of 500-1100nm.
The geometry of the lens is meticulously designed, with an edge thickness of 1.8mm and a center thickness of 2.6mm. The lens's effective focal length (EFL) is 4.5mm, and it has a back focal length (BFL) of 3.7mm. The first and second radii (R1 and R2) are 6.58mm and -6.58mm respectively, contributing to its double-convex shape.
This lens is a spherical lens, which is a type of lens where the two surfaces are parts of spheres. The base shape is circular, making it suitable for a wide range of applications.
