33-357-INK 12.0mm Dia. x 36.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 33-357-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.0mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750nm and 1550nm. The lens features a front and back coating of edm nir-ii std curve, which enhances its performance in the NIR II range.
The lens has a thickness of 1.79mm at the edge and 3.0mm at the center, with an effective focal length (EFL) of 30mm. The front surface of the lens has a radius of curvature (R1) of 15.5mm, and the back focal length (BFL) is 28.02mm. The lens is made of N-BK7 Schott, a popular optical glass known for its excellent transparency in the visible and near-infrared regions.
The lens is inked, which is a process that adds a dye to the lens to make it easier to handle and identify. This can be particularly useful in a lab or manufacturing setting where multiple lenses may be in use.
