111-0208E 25.4 mm Dia. x 40 mm FL; Uncoated; Double-Convex Lens
The 111-0208E is a double-convex lens with a base shape of a circle, designed and manufactured by EKSMA Optics. This 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 25.4 mm and a thickness at the edge of 1.9 mm, while the center thickness is 6 mm. The effective focal length (EFL) of this lens is 40 mm, making it suitable for various applications.
The lens features a double-convex geometry with radii of curvature R1 and R2 being 40.4 mm and -40.4 mm respectively. The inner and outer radii are both zero. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, this lens is still capable of delivering high-quality performance, especially in applications where coating is not a critical factor.
The lens is designed to work with a wavelength of 546 nm, making it suitable for use in a wide range of optical systems. It is important to note that the lens is spherical in shape, which is a common feature in many optical lenses. This shape helps to focus light onto a single point, making it ideal for various applications.
