38-420-INK 18.0mm Dia. x 50.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex lens, type Spherical, with a circular base shape, sourced from the renowned optical vendor, Edmund Optics. The lens is currently in stock and available for immediate purchase through their website.
The lens boasts an 18.0mm diameter and a thickness of 1.28mm at the edge, with a center thickness of 2.9mm. The effective focal length (EFL) is 50.0mm, and the first radius of curvature (R1) is 25.84mm. The back focal length (BFL) is 48.09mm, and both the inner and outer radii are 0mm.
The lens is made from N-BK7 Schott, a popular optical glass, and is coated with the EDM NIR-II STD curve on both the front and back surfaces. This coating enhances the lens's performance in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm.
Please note that the wavelength specified is 587.6nm, which is in the visible light spectrum. However, the lens's primary use is in the NIR spectrum due to its specialized coating.
This lens is an excellent choice for applications that require high-quality optical performance in the NIR spectrum.
