49-943-INK 18 mm Dia. N-BAF10/N-SF57 Achromatic Doublet; EFL=22.5mm VIS 0° 425-675nm

The 49-943-INK is an 18 mm diameter achromatic doublet lens, designed and manufactured by Edmund Optics. This lens is specifically engineered for use within the visible light spectrum, spanning from 425 to 675 nanometers. The lens boasts an effective focal length (EFL) of 22.5mm, making it suitable for a wide range of optical applications.

The lens is composed of two distinct materials, N-BAF10 and N-SF57, both sourced from Schott. These materials are carefully selected for their optical properties, contributing to the lens's overall performance. The lens is coated with EDM VIS-0 standard curve coatings on both the front and back surfaces, further enhancing its capabilities.

The geometry of the lens is meticulously designed, with a thickness at the edge of 8.03mm and a center thickness of 8.7mm. The lens also features a central thickness 'a' of 3mm, adding to its structural integrity. The inner and outer radii of the lens are 0mm, indicating a circular shape.

This lens is a multiplet, meaning it is composed of multiple elements. The radii of these elements are R1: 15.83mm, R2: -12.65mm, and R3: -47.42mm. This complex design allows the lens to achieve its high level of performance.

The lens is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status. For more detailed information, users are encouraged to visit the provided weblink.
