111-0440E 38.1 mm Dia. x 700 mm FL; Uncoated; Double-Convex Lens
The 111-0440E is a high-quality Double-Convex Lens, sourced from EKSMA Optics, a renowned vendor in the optical components industry. This lens is designed with a base shape of Circular and features a Spherical geometry, making it suitable for a wide range of optical applications.
The lens has a diameter of 38.1 mm and a thickness edge of 4.5 mm, ensuring durability and robustness. The thickness center is 5 mm, providing a balanced structure for optimal performance. The effective focal length (EFL) of this lens is 700 mm, making it ideal for applications that require long-focus lenses.
The curvature of the lens is defined by its first and second radii, R1 and R2, which are 725.4 mm and -725.4 mm respectively. These radii contribute to the lens's double-convex shape, which is designed to focus light onto a single point. The lens does not have any coating, which makes it suitable for applications where coating is not required or preferred.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. The wavelength for this lens is 546 nm, which is within the visible light spectrum.
