45-162 25mm Dia. x 35mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm

The 45-162 is a high-quality double-convex lens, boasting a 25mm diameter and a focal length of 35mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for immediate purchase, as indicated by its valid weblink status.

The lens is crafted from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It features a double-convex geometry, characterized by its two convex surfaces that curve outwards. This design is particularly effective for focusing light, making it ideal for a wide range of applications.

The 45-162 lens is coated with MgF2, a type of anti-reflective coating that reduces surface reflections and increases transmission. This coating is standard across both the front and back surfaces, following the EDM MgF2 STD curve. It is designed to operate within the wavelength range of 400-700nm, making it suitable for use in various optical systems.

The lens's geometry includes a 2mm edge thickness and a 6.6mm center thickness. The effective focal length (EFL) is 35mm, while the back focal length (BFL) is 32.81mm. The first and second radii of curvature are 35.09mm and -35.09mm, respectively. The lens's inner and outer radii are both zero, indicating a uniform curvature across the lens surface.
