The 49-378-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 30 mm, is designed for use in the visible (VIS) and near-infrared (NIR) spectrum, specifically catering to the wavelength range of 400-1000nm.
The lens is a multiplet, featuring a complex geometry that includes a center thickness of 4.5, an edge thickness of 6.12, and inner and outer radii of 0. The effective focal length (EFL) of this lens is 300mm, making it suitable for applications that require a longer focal length.
The lens is composed of two types of glass, N-BK7 and N-SF5, both from Schott. These materials are known for their excellent optical properties, making them ideal for use in achromatic doublets. The lens is coated with EDm VISNIR0SP2002000 on both the front and back surfaces, enhancing its performance in the specified wavelength range.
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website through the provided weblink.
