45-101 15mm Dia. x 22.5mm FL Uncoated; Double-Convex Lens

The 45-101 is a spherical lens with a base shape of a circle, sourced from the reputable vendor, Edmund Optics. This lens is a Double-Convex type, characterized by its convex-convex geometry, which makes it suitable for a wide range of optical applications.

The lens has a diameter of 15mm and a thickness of 2.54mm at the edge, while the center thickness is 4.2mm. The effective focal length (EFL) of this lens is 22.5mm, which is a crucial parameter in determining the lens's overall magnification and focusing capabilities.

The 45-101 lens has a back focal length (BFL) of 21.29mm and a clear aperture, indicated by its inner and outer radii being zero. The radii of curvature for this lens are r1 = 34.36mm and r2 = -34.36mm, which contribute to its double-convex shape.

This lens is made from n-SF11 Schott, a high-index glass with excellent optical properties. The lens is uncoated, which means it does not have any additional layers to enhance its light transmission or protect it from environmental factors. However, uncoated lenses can be advantageous in certain applications where specific reflectance properties are required.

The lens is designed to operate at a wavelength of 587.6nm, making it suitable for applications that require high precision and accuracy in the visible light spectrum.
