38-354 12.5mm Dia. x 20mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 38-354 is a Plano-Convex Spherical Lens, sourced from Edmund Optics, designed for use within the near-infrared (NIR) spectrum, specifically between 600-1050nm. This lens boasts a 12.5mm diameter, with a 1.4mm thickness at the edge and a 3.5mm thickness at the center. The effective focal length (EFL) of this lens is 20mm, making it suitable for a variety of optical applications.
The lens's front and back surfaces are coated with the EDM NIR-I Standard Curve coating, enhancing its performance within the NIR spectrum. The lens's geometry is defined by an inner radius of 0mm and an outer radius of 0mm, indicating a plano surface on the lens's incident side. The radius of curvature on the lens's exit side is 10.34mm, and the back focal length (BFL) is 17.69mm.
This lens is made from N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion. The material's properties make it ideal for use in a wide range of optical systems, including beam expanders, collimators, and objectives.
