LC7759-E4 25.4 mm Dia. ZnSe Plano-Concave Lens; EFL=-25.4mm 2-13µm

The LC7759-E4 is a 25.4 mm diameter Plano-Concave Spherical Lens, designed for use in the infrared spectrum with a center wavelength of 10600 nm. This lens is sourced from Thorlabs, a leading global manufacturer of photonics components.

The lens is crafted from ZnSe (Zinc Selenide), a material with excellent optical properties in the infrared region. The lens features a plano-concave geometry, with a concave radius of -35.6 mm and an effective focal length (EFL) of -25.4 mm. This geometry is designed to diverge light, making it suitable for applications such as beam expansion or collimation.

The lens has a center thickness of 2 mm, providing a balance between durability and optical performance. The inner and outer radii are both 0 mm, indicating a uniform curvature across the lens surface.

The LC7759-E4 is coated with Thorlabs' E4ZnSeARC2000 coating on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and increase transmission, enhancing the overall performance of the lens.
