The LA1134-C is a Plano-Convex lens, part of the extensive catalog of optical elements offered by Thorlabs. This lens is designed for use in the 1050-1700nm wavelength range, making it suitable for a variety of applications in the infrared spectrum.
The lens is made from N-BK7, a popular glass type in the optical industry due to its excellent optical properties and wide transmission range. The lens has a diameter of 1 inch (25.4mm) and a thickness of 2mm at the edge, which gradually increases to 4.7mm at the center. This design allows for a focal length of 60 meters, providing a large working distance and a wide field of view.
The front and back surfaces of the lens are coated with a broadband anti-reflection coating (tho c bbar), which reduces surface reflections and increases transmission. This coating is designed to operate over a wide range of wavelengths, from 1050nm to 1700nm, making the lens highly versatile.
The lens is spherical in shape, with a radius of curvature of 30.9mm on the convex side. This shape, combined with the lens's large diameter and long focal length, makes it ideal for use in imaging systems, beam shaping, and other applications where a large, collimated beam is required.
