49-782-INK 25.4 mm Dia. N-BAK1/N-SF8 Achromatic Doublet; EFL=88.9mm VIS 0° 425-675nm
The 49-782-INK is a high-quality achromatic doublet lens, boasting a 25.4 mm diameter and an effective focal length (EFL) of 88.9mm. This lens is designed for use within the visible light spectrum, specifically between 425-675nm.
The lens is composed of two types of glass, N-BAK1 and N-SF8, both from the reputable Schott brand. This combination helps to correct chromatic aberration, a common issue in optics where different wavelengths of light are focused at different points.
The lens features a standard curvature coating on both the front and back surfaces, denoted as 'edm vis-0 std curve'. This coating aids in reducing surface reflections and enhances the overall transmission of light through the lens.
The geometry of the lens is carefully crafted, with an edge thickness of 8.07mm and a center thickness of 6mm. The lens also features an inner radius of 0mm and an outer radius of 0mm. The r1, r2, and r3 radii are 56.98mm, -40.06mm, and -162.82mm respectively, contributing to the lens's precise optical performance.
The lens is sourced from Edmund Optics, a leading supplier of optical components. The item data indicates that the lens is currently in stock, ensuring quick and reliable delivery for your optical system needs.
