63-576 15mm Dia. x 25mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm
This is a high-quality double-convex lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as the 63-576 model, boasts a diameter of 15mm and a focal length of 25mm, making it suitable for a wide range of optical applications.
The lens is constructed from Schott's n-BK7 glass, a material known for its excellent optical properties and broad transmission range. This particular lens is designed to transmit light within the 400-700nm wavelength range, which covers the visible light spectrum.
The lens surfaces are coated with MgF2, a material known for its ability to reduce reflection and increase transmission. This coating is standard across both the front and back surfaces, following Edmund Optics' standard curve. This ensures optimal performance and durability, making the lens less susceptible to damage from environmental factors or frequent handling.
The geometry of the lens is also noteworthy. It has an edge thickness of 1.22mm and a center thickness of 3.5mm. The front and back radii of curvature are 25.23mm and -25.23mm, respectively, while the back focal length is 23.82mm. The lens's base shape is circular, and its shape is spherical, which is ideal for focusing light onto a single point.
