67-444 3.0mm Dia. x 12.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a 67-444 3.0mm Dia. x 12.0mm FL Plano-Convex lens, specifically designed for use in the near-infrared (NIR) spectrum, covering the wavelength range of 750-1550nm. The lens is sourced from the reputable optical components vendor, Edmund Optics.
The lens is characterized by its spherical geometry, with a base shape of a circle. It has a diameter of 3mm and a thickness at the edge of 0.9mm, while the thickness at the center is 1.08mm. The effective focal length (EFL) of the lens is 12mm, making it suitable for a variety of optical applications.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The front and back surfaces of the lens are coated with Edmund Optics' standard NIR-II coating, which enhances its performance in the NIR spectrum.
The lens's inner and outer radii are both 0, indicating a plano-convex design. The first radius of curvature (R1) is 6.2mm, and the back focal length (BFL) is 11.29mm.
