The 49-276 is a high-quality achromatic doublet lens, sourced from the renowned optical component manufacturer, Edmund Optics. This lens boasts a 5 mm diameter and an effective focal length (EFL) of 10 mm, designed for use within the visible light spectrum, specifically between 425-675 nm.
The lens is constructed from two distinct materials, N-BAF10 and N-SF10, both from Schott. These materials are known for their excellent optical properties, contributing to the lens's high performance. The lens features a standard anti-reflective coating on both the front and back surfaces, further enhancing its light transmission capabilities.
The lens geometry is intricately designed, with a center thickness of 1.73 mm and an edge thickness of 2.22 mm. The lens's first and second radii are 7.17 mm and -4.39 mm, respectively, while the third radius is -33.96 mm. The lens's inner and outer radii are both zero, indicating a circular shape.
This lens is a multiplet, meaning it is composed of multiple optical elements. The multiplet design allows for superior optical performance, making it suitable for a wide range of applications. The 49-276 is currently in stock and available for immediate purchase through the Edmund Optics website.
