49-778 25.4 mm Dia. N-BAF10/N-SF6 Achromatic Doublet; EFL=38.1mm VIS 0° 425-675nm
The 49-778 is a high-quality achromatic doublet lens, boasting a 25.4 mm diameter and an effective focal length of 38.1mm. This lens is designed for use in the visible light spectrum, specifically between 425-675nm.
The lens is composed of two elements, made from N-BAF10 and N-SF6 materials, both sourced from Schott. These materials are known for their excellent optical properties, contributing to the lens's high performance. The lens is coated with the EDM VIS-0 standard curve on both the front and back surfaces, further enhancing its capabilities.
The lens's geometry is carefully designed for optimal performance. It features an inner radius of 0mm, an outer radius of 0mm, and a center thickness of 10.5mm. The edge thickness is 9.44mm, and the lens has a central thickness 'a' of 3mm. The lens's base shape is circular, and it is classified as a multiplet due to its multiple elements.
This lens is available from Edmund Optics and is currently in stock. For more information, including pricing and availability, please refer to the provided weblink.
