49-354 25 mm Dia. S-BAH11/N-SF10 Achromatic Doublet; EFL=40mm VIS-NIR 400-1000nm

The 49-354 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is specifically designed for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning 400-1000nm. The lens boasts a 25mm diameter and an effective focal length (EFL) of 40mm, making it a versatile choice for a wide range of optical applications.

The lens is composed of two elements: S-BAH11 from Ohara and N-SF10 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-NIR 0SP2002000 on both the front and back surfaces, further enhancing its capabilities in the VIS-NIR spectrum.

The lens geometry is meticulously designed, with a center thickness of 9.5mm and edge thickness of 8.54mm. The radii of the lens surfaces are R1=27.97mm, R2=-18.85mm, and R3=-152.94mm. The lens also features an inner radius of 0mm and an outer radius of 0mm.
