47-699-INK 15 mm Dia. S-BAH11/N-SF10 Achromatic Doublet; EFL=25mm VIS 0° 425-675nm
The 47-699-INK is a high-quality achromatic doublet lens, sourced from Edmund Optics, with a diameter of 15 mm and a focal length of 25 mm. This lens is designed for visible light applications, specifically within the wavelength range of 425-675 nm.
The lens is composed of two elements: S-BAH11 from Ohara and N-SF10 from Schott. Both elements are coated with EDM VIS-0 standard curve coatings on both the front and back surfaces, ensuring optimal light transmission and reducing unwanted reflections.
The lens geometry is meticulously designed, with an inner radius of 0 mm, an outer radius of 0 mm, and a center thickness of 6.27 mm. The edge thickness is 6.06 mm, and the radii of curvature are r1 = 17.97 mm, r2 = -11.2 mm, and r3 = -85.31 mm.
This lens is a multiplet, meaning it is composed of multiple elements to correct optical aberrations and improve image quality. The lens is currently in stock and available for purchase through the provided weblink.
