LE1202-C 25.4 mm Dia. N-BK7 Positive Meniscus Lens; EFL=200mm 1050-1700nm

The LE1202-C is a 25.4 mm diameter Spherical Lens with a Positive Meniscus shape, sourced from the reputable vendor Thorlabs. This lens is specifically designed for use within the wavelength range of 1050-1700nm, making it suitable for a variety of applications within this spectrum.

The lens features an effective focal length (EFL) of 200mm, which is the distance from the center of the lens to the point at which the light rays converge. This is a crucial factor in determining the lens's magnification and field of view. The LE1202-C also has a front radius (R1) of 66.2mm and a back radius (R2) of 182.2mm, contributing to its overall optical performance.

The lens is constructed from N-BK7 Schott glass, a popular choice due to its excellent optical properties and versatility. The base shape of the lens is circular, with a thickness at the edge of 2mm and a center thickness of 2.8mm. The lens also features a Broadband Anti-Reflection Coating (BBAR) on both the front and back surfaces, which helps to minimize losses due to reflection and increase the overall transmission of light.

The LE1202-C is currently in stock and available for immediate purchase from the Thorlabs website, as indicated by its 'Valid - in stock' web link status. This lens is a reliable and high-performing option for those requiring a Positive Meniscus lens within the 1050-1700nm wavelength range.
