47-704 18 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=27mm VIS 0° 425-675nm

The 47-704 is an 18 mm diameter achromatic doublet lens, designed and manufactured by Edmund Optics. This lens boasts an effective focal length (EFL) of 27mm, making it suitable for a wide range of applications. The lens is specifically coated with the EDM VIS-0 standard curve on both the front and back surfaces, enhancing its performance in the visible light spectrum, which spans from 425 to 675nm.

The lens is constructed from two types of Schott glass: N-BAF10 and N-SF10. These materials are chosen for their excellent optical properties, contributing to the lens's high-quality performance. The lens's geometry is carefully designed, with a center thickness of 7.67mm, an edge thickness of 6.62mm, and inner and outer radii of 0mm. The lens also features a central thickness 'a' of 1.6mm, further enhancing its optical performance.

The 47-704 is a multiplet lens, meaning it is composed of multiple elements. This design allows for the correction of various optical aberrations, resulting in a sharper, clearer image. The lens's base shape is circular, contributing to its versatility and applicability in various optical systems.
