LA1270-C N-BK7 Plano-Convex Lens; Dia:18.0 mm; f=25.0 mm ARC 1050-1700nm

The LA1270-C is a high-quality Plano-Convex lens from Thorlabs, designed for use in a wide range of optical applications. This lens is made from N-BK7 glass, a popular material known for its excellent optical properties and high damage threshold. The lens has a diameter of 18.0 mm and a focal length of 25.0 mm, making it a versatile choice for many setups.

The lens features an anti-reflection coating, designed to reduce surface reflections and increase transmission across the 1050-1700nm wavelength range. This coating is applied to both the front and back surfaces of the lens, ensuring optimal performance in a variety of conditions.

The geometry of the lens is carefully controlled, with a thickness at the edge of 1.8 mm and a center thickness of 5.5 mm. The lens has a spherical shape, with a radius of curvature of 12.9 mm on the curved (convex) side. The back surface of the lens is flat (plano), providing a large, flat area for beam transmission.

This lens is part of Thorlabs' extensive catalog of optical elements, and is available for purchase directly from their website. According to the latest information, the lens is currently in stock, ensuring quick delivery for your optical project needs.
