111-0426E 38.1 mm Dia. x 300 mm FL; Uncoated; Double-Convex Lens

The 111-0426E is a high-quality Double-Convex Lens, sourced from EKSMA Optics, a renowned vendor known for their extensive catalog of optical elements. This lens, with a base shape of Circular, is designed for use in a variety of optical applications, thanks to its precise geometry and material composition.

The lens has a diameter of 38.1 mm, ensuring a wide field of view while maintaining a compact form factor. The edge thickness is 3.8 mm, providing structural integrity and resistance to deformation. The center thickness is 5 mm, optimized for minimal spherical aberration. The effective focal length (EFL) of this lens is 300 mm, making it suitable for applications that require moderate magnification.

The lens is made from n-BK7 Schott, a popular optical glass known for its excellent optical properties. It has a refractive index of 1.5168 at the wavelength of 546 nm, ensuring high light transmission and minimal distortion. The radii of curvature for the first and second surfaces are 310.4 mm and -310.4 mm respectively, providing a symmetrical double-convex profile that minimizes optical aberrations.

Notably, this lens is uncoated, offering bare glass surfaces that can be used as is or coated according to specific application requirements. The lack of coating makes this lens ideal for applications where cost-effectiveness is a priority, or where specific coating properties are not required.
