63-587 25mm Dia. x 30mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm
This is a 25mm diameter, double-convex lens with a focal length of 30mm, designed for use within the wavelength range of 400-700nm. The lens is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock.
The lens is made from n-SF5 Schott, a high-quality optical glass known for its excellent transmission properties and low autofluorescence. This makes it an ideal choice for a wide range of applications, including fluorescence microscopy and other sensitive optical systems.
The lens features a standard MgF2 coating on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, particularly within the specified wavelength range. The coating is applied using a standard curve, ensuring consistent performance and reliability.
The geometry of the lens includes an edge thickness of 1.41mm and a center thickness of 5.5mm. The front and back radii of curvature are 39.22mm and -39.22mm respectively, resulting in a back focal length of 28.31mm. The lens has no inner or outer radius, indicating a uniform thickness across the entire surface.
