67-529-INK 18.0mm Dia. x 54.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-529-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 18.0mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750 and 1550nm.
The lens features a front and back coating of EDM NIR-II STD CURVE, providing optimal performance within its specified wavelength range. The lens's geometry includes a thickness of 1.53mm at the edge and 4mm at the center, with an effective focal length (EFL) of 22.5mm. The radius of curvature for the first surface (R1) is 17.66mm, and the back focal length (BFL) is 20.26mm.
The lens material is n-SF11 Schott, a popular choice for its high refractive index and low dispersion. The lens is circular in base shape and has no inner or outer radius, indicating a uniform curvature throughout.
According to the vendor's website, the lens is currently in stock, making it readily available for immediate use. The link provided leads to the product page on Edmund Optics' website, where users can find more detailed information, purchase the lens, or explore other related products.
