45-176 4.5mm Dia. x 4.5mm FL; Uncoated; Double-Convex Lens
The 45-176 4.5mm Dia. x 4.5mm FL is a high-quality, uncoated, double-convex lens sourced from Edmund Optics. This lens, with a diameter of 4.5mm, is designed for use in a variety of optical applications, particularly where a spherical lens with a convex-convex base shape is required.
The lens features a double-convex geometry, with an inner radius of 0mm and an outer radius of 0mm. The thickness at the edge of the lens is 1.8mm, while the thickness at the center is 2.6mm. The effective focal length (EFL) of the lens is 4.5mm, and the back focal length (BFL) is 3.7mm.
The lens is made from n-lasf44 Schott, a material known for its excellent optical properties. It is designed to work with a wavelength of 587.6nm. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, this may be beneficial in certain applications where a specific coating is not required.
The lens is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink. With its robust design and high-quality materials, the 45-176 4.5mm Dia. x 4.5mm FL is an excellent choice for a wide range of optical applications.
