LB7834-E3 25.4 mm Dia. ZnSe Double-Convex Lens; EFL=75mm 7-12µm
The LB7834-E3 is a high-quality Spherical Lens (Convex-Convex) with a 25.4 mm diameter, sourced from the renowned optical component manufacturer, Thorlabs. This lens is specifically designed for use in the infrared spectrum, with a wavelength of 10600 nm.
The lens features a double-convex geometry, with a center thickness of 2.8 mm and an edge thickness of 2 mm, ensuring excellent optical performance. The effective focal length (EFL) of this lens is 75 mm, making it suitable for a wide range of applications that require precise focusing and imaging capabilities.
The LB7834-E3 is fabricated from ZnSe (Zinc Selenide) material, identified as "znse connolly" in the item data. This material is known for its excellent transmission properties in the infrared region, making it an ideal choice for applications in this spectrum.
The lens is coated with a broadband anti-reflection coating, specifically the "tho e3znsearc7000120" coating, on both the front and back surfaces. This coating significantly reduces surface reflections, thereby improving transmission and enhancing the overall performance of the lens.
