40540 38.1 mm Dia. x 50.0 mm FL; Uncoated; Plano-Convex Lens
The 40540 is a Plano-Convex lens, a type of spherical lens, sourced from MKS/Newport. This lens is uncoated and features a circular base shape. The lens has a diameter of 38.1 mm and a thickness at the edge of 3 mm. The effective focal length (EFL) of the lens is 50 mm, and the radius of curvature (R1) is 25.835 mm. The back focal length (BFL) is also 25.835 mm, and the inner radius is 0 mm.
The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens is designed to operate at a wavelength of 589 nm. The lens's shape is spherical, a common choice for its ease of manufacturing and good image quality.
This lens is ideal for applications that require a simple, high-quality lens. Its uncoated surface makes it suitable for use in environments where anti-reflective coatings are not necessary. The lens's large diameter and long focal length make it suitable for use in systems where a wide field of view and high magnification are required.
