111-1426E 38.1 mm Dia. x 300 mm FL; Uncoated; Double-Convex Lens
The 111-1426E is a double-convex lens, a type of spherical lens, sourced from EKSMA Optics. This lens boasts a diameter of 38.1 mm and an effective focal length (EFL) of 300 mm, making it suitable for a wide range of optical applications.
The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors. This can be advantageous in certain applications where the natural properties of the material are desired, or where cost is a significant factor.
The base shape of the lens is circular, and it has a center thickness of 5 mm and an edge thickness of 3.7 mm. The first radius of curvature (r1) is 284.8 mm, and the second radius of curvature (r2) is -284.8 mm, indicating that both surfaces of the lens are convex. The inner and outer radii are 0, suggesting that the lens does not have any peripheral features or additional layers.
The lens is made from UVFS MAL-1965, a material specifically designed for use in the ultraviolet (UV) spectrum at a wavelength of 355 nm. This makes the lens particularly suitable for UV applications, such as UV imaging or spectroscopy.
