12-925 12.5 mm Dia. N-SSK8/N-SF10 Mounted Achromatic Doublet; EFL=30mm MgF2 400-700nm
The 12-925 is a high-quality mounted achromatic doublet lens, offered by the renowned optical vendor, Edmund Optics. This lens, with a diameter of 12.5 mm, is designed for use in the spectral range of 400-700nm, making it suitable for a wide range of applications in the visible light spectrum.
The lens features a focal length of 30mm, indicated by the EFL (Effective Focal Length) parameter. This EFL, combined with the lens's diameter, allows for a compact and efficient optical system. The lens is constructed from two types of glass, N-SSK8 and N-SF10, both from Schott, ensuring high-quality optical performance.
The lens's geometry is carefully designed, with a center thickness of 4.5mm and edge thickness of 4.39mm. The radii of curvature for the three surfaces are r1=15.97mm, r2=-15mm, and r3=-528.23mm. These parameters contribute to the lens's excellent imaging properties.
The lens is coated with Edmund Optics' standard MgF2 coating on both the front and back surfaces. This coating, designed for the 400-700nm range, enhances the lens's transmission and reduces reflections, further improving its performance.
The lens is readily available and in stock, as indicated by its weblink status. For more information, users can refer to the provided weblink, which leads to the product's page on the Edmund Optics website.
