45-409-INK 12.5 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=80mm MgF2 400-700nm
This is a 12.5 mm diameter achromatic doublet lens, model 45-409-INK, sourced from Edmund Optics. The lens is designed for use in the 400-700nm spectral range, making it suitable for a wide range of optical applications. The lens features a focal length of 80mm, provided by an N-BK7/N-SF5 achromatic doublet design. This design helps to minimize chromatic aberration, ensuring high-quality imaging.
The lens has a front coating of EDM MgF2 std curve and a back coating of EDM MgF2 std curve. These coatings are designed to enhance the lens's performance by reducing reflection and improving transmission. The lens's geometry includes a thickness of 3.12mm at the edge, a center thickness of 2.1mm, and a center thickness 'a' of 1.6mm. The lens's inner and outer radii are 0, indicating a circular shape.
The lens is available for purchase directly from the Edmund Optics website, where it is currently in stock. For more detailed information, including technical specifications and performance data, please refer to the product's webpage.
