LA7234-E2 25.4 mm Dia. ZnSe Plano-Convex Lens; EFL=750mm 4.5-7.5µm
This LA7234-E2 optical lens, sourced from Thorlabs, is a Spherical Lens of the Plano-Convex type, featuring a Circular base shape. The lens has a diameter of 25.4 mm and a thickness that varies from 2 mm at the edge to 2.1 mm at the center. The Effective Focal Length (EFL) of this lens is 750 mm, making it suitable for a range of applications that require precise focusing.
The lens is made from ZnSe (Zinc Selenide) material, identified as 'znse marple-1964' in the material database. It is designed to work with a wavelength of 10600 nm. The lens is coated with 'tho e2znsearc4500750' on both the front and back surfaces, which is a specialized anti-reflection coating that reduces surface reflections and increases transmission.
The lens's geometry is defined by its inner and outer radii, which are 0 mm in this case, and its 'r1' value of 1052 mm. This specific lens is in stock and available for immediate purchase through the provided weblink.
