LB7936-E3 25.4 mm Dia. ZnSe Double-Convex Lens; EFL=25.4mm 7-12µm
The LB7936-E3 is a high-quality Spherical Lens (Convex-Convex) with a diameter of 25.4 mm, sourced from the renowned optical component manufacturer, Thorlabs. This lens is designed for use in the 7-12 µm wavelength range, making it suitable for a variety of infrared applications.
The lens features a double-convex geometry, with a center thickness of 4.3 mm and an edge thickness of 2 mm. The effective focal length (EFL) is 25.4 mm, which is also the same as the diameter, making it a convenient choice for systems where space is a constraint. The lens has a front and back coating of tho e3znsearc7000120, which enhances its performance in the specified wavelength range.
The LB7936-E3 is made of ZnSe (Zinc Selenide) material, identified by the Material ID "znse connolly". This material is known for its excellent transmission properties in the infrared region, making it a popular choice for IR applications. The lens is currently in stock and available for immediate shipping, as indicated by its weblink status.
