LD7071-E3 25.4 mm Dia. ZnSe Double-Concave Lens; EFL=-100mm 7-12µm

The LD7071-E3 is a high-quality double-concave lens offered by Thorlabs, designed specifically for use in the 7-12 µm wavelength range. This lens is made from ZnSe (Zinc Selenide) material, identified as "znse connolly" in the material database.

The lens features a base shape of a circle, with a diameter of 25.4 mm and a center thickness of 2 mm. The lens's geometry includes an effective focal length (EFL) of -100 mm, making it a powerful tool for focusing or diverging light in various applications.

The LD7071-E3's surface geometry is spherical, with radii of curvature of -281.1 mm and 281.1 mm for the first and second surfaces, respectively. The lens does not have an inner or outer radius.

This lens comes with a broadband anti-reflection coating, specifically the "tho e3znsearc7000120" coating, on both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections and increasing transmission in the specified wavelength range.
