The 47-358 is a Double-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 12mm diameter and a focal length of 12mm, making it a versatile choice for various optical applications. The lens is constructed with a base shape of a circle, ensuring a uniform light path.
The geometry of the lens is meticulously designed. The edge thickness measures 1.41mm, while the center thickness is 3.85mm, providing excellent structural integrity. The effective focal length (EFL) is 12mm, and the radii of curvature are R1 = 15.34mm and R2 = -15.34mm, contributing to its double-convex shape. The back focal length (BFL) is 10.79mm, and both the inner and outer radii are 0mm.
The lens is made from n-SF5 Schott, a high-quality optical material known for its excellent transmission properties in the visible spectrum. The lens is coated with the EDM VIS-0 STD CURVE coating on both the front and back surfaces, enhancing its performance in the 425-675nm wavelength range.
