49-335 15 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=30mm VIS-NIR 400-1000nm
The 49-335 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 to near-infrared spectrum, spanning from 400 to 1000nm. The lens boasts a 15mm diameter and a focal length of 30mm, making it a versatile choice for a wide range of optical applications.
The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, which are renowned for their excellent optical properties. The use of these materials in a doublet configuration helps to correct chromatic aberration, ensuring sharp, clear images across the entire spectral range.
The lens features a robust geometry, with a thickness of 5.88mm at the edge and 6mm at the center. The center thickness can be further reduced to 1.5mm if required, providing additional flexibility for optical system design. The lens also features a 20.72mm radius of curvature on the first surface and a -13.17mm radius on the second, followed by a -128.44mm radius on the third surface.
The 49-335 is coated with Edmund Optics' VIS-NIR coating (edm visnir0sp2002000), which is applied to both the front and back surfaces. This coating is designed to enhance the lens' performance in the visible to near-infrared spectrum, reducing reflection and improving transmission.
