LC7235-E2 25.4 mm Dia. ZnSe Plano-Concave Lens; EFL=-50mm 4.5-7.5µm
The LC7235-E2 is a 25.4 mm diameter Plano-Concave Spherical Lens, designed and manufactured by Thorlabs. This lens is specifically engineered for use in the infrared spectrum, with a wavelength of 10600 nm, making it suitable for a wide range of applications in this region.
The lens is made from ZnSe (Zinc Selenide), a material known for its excellent optical properties in the infrared spectrum. The lens features a plano-concave geometry, with a center thickness of 2 mm and an effective focal length (EFL) of -50 mm. This negative focal length indicates that the lens will diverge light, making it ideal for use in beam expanding or collimating applications.
The lens is coated with Thorlabs' E2ZnSeARC coating, which is specifically designed for use in the infrared spectrum. This coating provides high transmission and excellent environmental resistance, ensuring the lens maintains its performance even in challenging conditions.
The LC7235-E2 is currently in stock and available for immediate purchase. For more information, including detailed specifications and pricing, please refer to the product webpage on Thorlabs' website.
