67-549-INK 25.0mm Dia. x 85.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-549-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 25.0mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750 and 1550nm. The lens is coated with the EDM NIR-II STD curve on both the front and back surfaces, ensuring optimal performance within its specified wavelength range.
The lens has a thickness of 1.68mm at the edge and 4.9mm at the center, providing a base shape that is circular. The effective focal length (EFL) of this lens is 50mm, and its radius of curvature (R1) is 25.84mm. The back focal length (BFL) is 46.75mm, and both the inner and outer radii are 0mm.
This lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens is inked, a process that typically involves applying a dye to the edge of the lens to indicate its orientation.
The item data provided does not specify the lens's thickness tolerance, surface quality, or other potential specifications. For more detailed information, it is recommended to visit the vendor's website or contact their sales team directly.
