LA7234-E3 25.4 mm Dia. ZnSe Plano-Convex Lens; EFL=750mm 7-12µm

This is the LA7234-E3, a 25.4 mm diameter ZnSe Plano-Convex lens, specifically designed for use in the infrared spectrum with a wavelength of 10600 nm. The lens is sourced from Thorlabs, a reputable vendor known for its high-quality optical components.

The LA7234-E3 is a Spherical Lens of the Plano-Convex type, featuring a Base Shape that is Circular. The lens has a diameter of 25.4 mm, with a thickness at the edge of 2 mm and a center thickness of 2.1 mm. The Effective Focal Length (EFL) of this lens is 750 mm, making it suitable for applications that require a longer focal length.

The lens is made from ZnSe (Zinc Selenide) material, identified as "znse connolly" in the material ID. This material is known for its excellent transmission properties in the infrared region, making it an ideal choice for applications in this spectrum.

The LA7234-E3 is coated with a front and back coating of "tho e3znsearc7000120". This coating is specifically designed to enhance the performance of the lens in the infrared spectrum, providing improved transmission and reduced reflection.
