LA1740-C N-BK7 Plano-Convex Lens; Dia:75.0 mm; f=85.0 mm ARC 1050-1700nm

The LA1740-C is a high-quality Plano-Convex lens, designed and manufactured by Thorlabs, a leading global supplier of photonics equipment. This lens is part of Thorlabs' extensive catalog of optical elements, and it is specifically designed for use in the 1050-1700nm wavelength range.

The lens is made from N-BK7, a type of borosilicate glass that is known for its excellent optical properties. N-BK7 is a common material in optical systems due to its low dispersion and high transmission in the visible and near-infrared regions. The lens has a diameter of 75.0 mm and a focal length of 85.0 mm, making it suitable for a wide range of applications.

The LA1740-C features a front and back coating of tho c bbar. This coating is designed to reduce reflection and increase transmission, enhancing the performance of the lens in its intended wavelength range. The lens has a spherical shape, with a radius of curvature of 43.8 mm on the convex side. The edge thickness of the lens is 3.0 mm, while the center thickness is 24.2 mm.

The LA1740-C is currently in stock, according to Thorlabs' website. Users can find more information about this lens, including detailed specifications and purchasing options, by visiting the product page at https://www.thorlabs.com/thorproduct.cfm?partnumber=LA1740-C.
