The 114-0206E is a double-concave lens with a base shape of a circle, sourced from EKSMA Optics. This lens is designed for use with a wavelength of 546 nm and is made from the material n-BK7 Schott. The lens features a diameter of 25.4 mm and a thickness at the edge of 6.5 mm, while the center thickness is 3 mm. The effective focal length (EFL) of this lens is -40 mm, making it a powerful tool for focusing or diverging light.
The lens's geometry includes two radii of curvature: r1 is -42 mm, and r2 is 42 mm. The inner radius is 0 mm, and the outer radius is also 0 mm. This specific lens is uncoated, which means it does not have any additional layers to protect it or alter its optical properties.
