49-364-INK 25 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=200mm VIS-NIR 400-1000nm

The 49-364-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 25 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, meaning it is composed of multiple optical elements. The primary materials used in its construction are N-BK7 and N-SF5, both renowned for their optical properties and sourced from Schott, a leading manufacturer of optical glass.

The lens has an effective focal length (EFL) of 200mm, making it suitable for applications that require a longer focal length. The geometry of the lens is carefully designed, with an edge thickness of 11.56mm and a center thickness of 8.5mm. The lens also features an inner radius of 0mm and an outer radius of 0mm, indicating a symmetrical design.

The lens is coated with edm visnir0sp2002000, a proprietary coating from Edmund Optics, on both the front and back surfaces. This coating is designed to enhance the lens' performance in the VIS-NIR spectrum, reducing unwanted reflections and increasing transmission.
