49-918 15.0mm Dia. x 18.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 49-918 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 15.0mm and a focal length of 18.0mm, making it a compact yet powerful optical component. The lens is made from n-sf5 Schott, a high-quality optical material known for its excellent transmission properties across a wide spectrum.
The 49-918 lens is coated with edm visnir0sp2002000 on both the front and back surfaces. This coating enhances its performance in the visible to near-infrared range, specifically between 400 and 1000nm. This makes the lens suitable for a wide range of applications, including but not limited to, spectroscopy, biomedical imaging, and machine vision.
The lens's geometry is another notable feature. It has an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature. The edge thickness is 1.4mm, while the center thickness is 4mm, providing a good balance between compactness and optical power.
