49-395-INK 50 mm Dia. N-BAK4/N-SF10 Achromatic Doublet; EFL=350mm VIS-NIR 400-1000nm

The 49-395-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 50 mm, is designed for use in the visible to near-infrared spectrum, spanning 400-1000nm. The lens is specifically engineered to minimize chromatic aberration, ensuring clear, focused images across the entire spectrum.

The lens features a focal length of 350mm, indicated by the EFL (Effective Focal Length) parameter. This long focal length makes it suitable for applications requiring high magnification or narrow fields of view. The lens is constructed from two types of glass, N-BAK4 and N-SF10, both from Schott, a leading manufacturer of high-precision optical glass. This combination ensures excellent optical performance and durability.

The lens is coated with EDm VIS-NIR 0SP2002000, a proprietary coating from Edmund Optics, on both the front and back surfaces. This coating enhances the lens's transmission in the visible to near-infrared spectrum, reducing unwanted reflections and improving overall image quality.

The 49-395-INK has a base shape of a circle, with a thickness of 10.07mm at the edge and 8mm at the center. The lens also has a central thickness of 4mm, providing structural rigidity and resistance to deformation. The lens's geometry, combined with its high-quality materials and coatings, makes it an ideal choice for a wide range of optical applications.
