111-0104E 12.7 mm Dia. x 12.7 mm FL; Uncoated; Double-Convex Lens
The 111-0104E is a spherical lens with a base shape of a circle, designed and manufactured by EKSMA Optics. This lens is a double-convex type, meaning it has two convex surfaces. The lens is made from the material n-bk7 schott, a popular choice in the optical industry due to its excellent optical properties.
The lens has a diameter of 12.7 mm and a thickness at the edge of 1.3 mm. The center thickness is 4.8 mm, providing a substantial structure for various applications. The effective focal length (EFL) of this lens is 12.7 mm, which is the same as its diameter, indicating a compact and powerful optical component.
The first radius of curvature (r1) is 12.3 mm, and the second radius of curvature (r2) is -12.3 mm. These specifications suggest that the lens has a strong focusing power, making it suitable for applications that require high-precision focusing. The inner and outer radii are both 0, indicating a uniform curvature throughout the lens.
This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, it can be customized with various coatings upon request. The lens is designed to work with a wavelength of 546 nm, a common wavelength used in various optical applications.
