LA1254-C N-BK7 Plano-Convex Lens; Dia:1 in; f=1500.0 mm ARC 1050-1700nm
The LA1254-C is a plano-convex lens with a diameter of 1 inch, designed and manufactured by Thorlabs. This lens is made from N-BK7 Schott glass, a popular material for its high refractive index and low dispersion. The lens has a focal length of 1500.0 mm, making it suitable for applications that require long focal lengths.
The lens features an antireflection coating, specifically designed for the wavelength range of 1050-1700nm. This coating reduces surface reflections, thereby increasing the amount of light transmitted through the lens. The coating is applied to both the front and back surfaces of the lens.
The geometry of the lens includes a thickness of 2mm at the edge and 2.1mm at the center. The lens has a spherical shape, with a radius of curvature of 775.2mm on the curved surface. The back focal length of the lens is 1498.6mm, and it has no inner or outer radius.
The lens is available for purchase directly from Thorlabs, and as per their website, it is currently in stock. The link to the product page on their website is provided for further information and verification.
