38-431-INK 25.4mm Dia. x 125.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex lens, type of spherical lens, with a circular base shape and a diameter of 25.4mm. The lens has a thickness of 1.74mm at the edge and 3mm at the center, with an effective focal length (EFL) of 125mm. The front and back surfaces of the lens are coated with the EDM NIR-II standard curve coating, designed for use in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm. The lens is sourced from Edmund Optics and is currently in stock, as indicated by the "weblink status" field.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, with a radius of curvature (R1) of 64.6mm and a back focal length (BFL) of 123.02mm. The lens material is n-BK7 Schott, a common material for optical lenses due to its excellent optical properties and wide transparency range.
This lens is a versatile option for applications that require NIR capabilities, such as night vision, thermal imaging, and spectroscopy. Its Plano-Convex design allows for a wide range of applications, from simple focusing tasks to more complex optical systems. The EDM NIR-II coating ensures optimal performance in the NIR spectrum, making this lens an ideal choice for users working in this range.
