49-941-INK 15 mm Dia. N-BAF10/N-SF57 Achromatic Doublet; EFL=20mm VIS 0° 425-675nm
The 49-941-INK is a high-quality Achromatic Doublet Lens, boasting a 15 mm diameter and effective focal length (EFL) of 20mm. This lens is meticulously crafted from two distinct materials, N-BAF10 and N-SF57, both sourced from the renowned optical glass manufacturer Schott.
The lens features a sophisticated geometry, with a thickness of 5.98mm at the edge, a central thickness of 6.8mm, and a thickness of 2mm at the center a. The inner and outer radii are optimized for superior performance. The lens's front and back surfaces are coated with EDm Vis-0 std curve, enhancing its light transmission capabilities within the visible spectrum of 425-675nm.
This lens is a multiplet, meaning it is composed of multiple optical elements. The curvature of these elements is designed to minimize chromatic aberration, a common issue in lens systems where different wavelengths of light are focused at different points. The 49-941-INK lens is a testament to Edmund Optics' commitment to delivering precision, quality, and performance.
The lens is currently in stock and available for purchase through the Edmund Optics website. For more detailed specifications and purchasing information, please refer to the provided weblink.
