49-377-INK 30 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=200mm VIS-NIR 400-1000nm
The 49-377-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 to near-infrared spectrum, specifically catering to the wavelength range of 400-1000nm.
The lens is a multiplet, meaning it is composed of multiple optical elements. In this case, it is made up of two different materials: N-BK7 and N-SF5, both from Schott. This combination helps to correct chromatic aberration, a common issue in lenses where different wavelengths of light are focused at different points.
The lens has an effective focal length (EFL) of 200mm, making it suitable for a variety of applications that require moderate to high magnification. The geometry of the lens is carefully designed, with a thickness at the edge of 6.15mm and a center thickness of 5mm. The lens also features an inner radius of 0 and an outer radius of 0, indicating a symmetrical design.
The 49-377-INK comes with a front and back coating of edm visnir0sp2002000. This coating is designed to enhance the lens' performance in the visible to near-infrared spectrum, reducing reflection and increasing transmission.
The lens is currently in stock and can be purchased directly from the Edmund Optics website, with the provided weblink offering a direct path to the product page.
