45-177 4.5mm Dia. x 4.5mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm
The 45-177 is a high-quality double-convex lens, boasting a 4.5mm diameter and a focal length of 4.5mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is currently in stock. The lens is made from the high-grade material, n-lasf44 schott, which ensures durability and excellent optical performance.
The lens features a double-convex geometry, with radii of curvature of 6.58mm for the first surface and -6.58mm for the second surface. This geometry results in a back focal length of 3.7mm. The lens has a central thickness of 2.6mm and an edge thickness of 1.8mm, providing a robust structure.
The 45-177 lens is coated with MgF2 on both the front and back surfaces. This coating, standard from Edmund Optics, is designed to optimize performance in the 400-700nm wavelength range. The coating enhances the lens's light transmission capabilities and reduces surface reflections, making it an ideal choice for various optical applications.
