32-625 25mm Dia. x 50mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm

This is a 25mm diameter, 50mm focal length double-convex lens, offered by the renowned optical vendor, Edmund Optics. The lens is made from the high-quality material, n-BK7 Schott, which is known for its excellent optical properties and durability.

The lens features a standard MgF2 coating on both the front and back surfaces, providing superior anti-reflection performance across the visible spectrum, specifically within the 400-700nm range. This coating enhances the lens's light transmission capabilities, reducing unwanted reflections and improving overall image quality.

The lens geometry includes a center thickness of 5mm and an edge thickness of 1.88mm, with radii of curvature of 50.8mm for the first surface and -50.8mm for the second surface. The back focal length is 48.29mm, and the lens has no inner or outer radius, indicating a uniform thickness across the lens.

This lens is an excellent choice for various applications that require high-quality imaging within the specified wavelength range. Its double-convex design and high-quality coating ensure excellent light transmission, low distortion, and high resolution, making it suitable for use in cameras, microscopes, beam shaping, and other optical systems.
