39-548 25.4mm Dia. x 35mm FL; Coated; ZnSe Plano-Convex Lens BBAR 8-12µm
The 39-548 is a Plano-Convex Spherical Lens, part of the extensive catalog of optical elements at 3DOptix. This lens, sourced from Edmund Optics, boasts a diameter of 25.4mm and a focal length of 35mm, specifically designed for the 8-12µm wavelength range.
The lens is made from ZnSe (Zinc Selenide) material, identified as "znse connolly" in the Material ID. This material is known for its excellent transmission in the infrared spectrum, making it ideal for applications such as thermal imaging and night vision.
The lens features a front and back coating of "edm dbbarl znse 812", a type of Broadband Anti-Reflective (BBAR) coating. This coating reduces reflection and increases transmission, enhancing the performance of the lens in its designated wavelength range.
The geometry of the lens includes a thickness of 2.03mm at the edge and 3.7mm at the center. The inner and outer radii are 0, indicating a plano surface on one side and a curved surface on the other. The effective focal length (EFL) is 35mm.
The lens is currently in stock and more information can be found on the Edmund Optics website.
