LA1805-AB 25.4 mm Dia. N-BK7 Plano-Convex Lens; EFL=30mm 400-1100nm
The LA1805-AB is a 25.4 mm diameter Plano-Convex lens made from N-BK7 Schott glass, a popular material for its high refractive index and low dispersion. This lens is designed for use in the 400-1100nm wavelength range, making it suitable for a wide range of optical applications.
The lens features an effective focal length (EFL) of 30mm, which is the distance from the lens's center to the focal point when the lens is imaging an object at infinity. The lens's geometry includes a 2mm thickness at the edge and an 8.6mm thickness at the center, with a clear aperture of 25.4mm.
The LA1805-AB lens is coated with Thorlabs' Anti-Reflection (AR) Broadband Black coating on both the front and back surfaces, reducing reflection losses and improving transmission. The shape of the lens is spherical, with a radius of curvature of 15.5mm on the convex side.
This lens is sourced from Thorlabs, a leading global manufacturer of photonics components and systems. The item data indicates that the lens is in stock, ensuring quick delivery for your optical project needs.
