11-428 25.4mm Dia. x 150mm FL; Coated; ZnSe Plano-Convex Lens BBAR 3-12µm
This is a 25.4mm diameter, 150mm focal length plano-convex lens made of ZnSe material, specifically designed for use in the 3-12µm wavelength range. The lens is sourced from Edmund Optics and is currently in stock.
The lens features a BBAR (Broadband Anti-Reflection) coating on both the front and back surfaces, which is identified as 'edm dbbarl znse 312'. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving overall system efficiency.
The lens has a thickness of 2.32mm at the edge and 2.7mm at the center. The inner and outer radii are both zero, indicating a plano surface on one side and a curved surface on the other. The radius of curvature of the curved surface is 210.4mm.
This lens is a spherical lens, which is a type of lens where the two surfaces are parts of spheres. Spherical lenses are the simplest type of lens and are widely used in various optical systems due to their simplicity and availability.
