47-658-INK 9 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=60mm VIS 0° 425-675nm

The 47-658-INK is a high-quality achromatic doublet lens, sourced from Edmund Optics, featuring a 9 mm diameter and an effective focal length (EFL) of 60 mm. This lens is specifically designed for the visible spectrum, covering a wavelength range of 425-675 nm, making it suitable for a wide range of applications.

The lens is constructed from two types of glass, N-BK7 and N-SF5, both from Schott, which are renowned for their excellent optical properties. The use of these materials in a doublet configuration helps to minimize chromatic aberration, ensuring high-quality imaging.

The lens geometry includes a thickness of 4.59 mm at the edge, with a central thickness of 3.5 mm. The radii of curvature are R1 = 36.51 mm, R2 = -26.33 mm, and R3 = -78.35 mm. The lens also features an inner radius of 0 mm and an outer radius of 0 mm.

The lens is coated with EDM Vis-0 std curve on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving image quality.

The lens is available in a multiplet shape, which provides flexibility in design and application.
