67-175-INK 25.0mm Dia. x 300.0mm FL; NIR I; Inked; Plano-Convex Lens NIR I 600-1050nm
The 67-175-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a base shape of a circle, has a diameter of 25.0mm and a thickness at the edge of 2.5mm, which gradually increases to a center thickness of 3.0mm. The effective focal length (EFL) of this lens is 300.0mm, making it suitable for applications requiring long focal lengths.
The lens's front and back surfaces are coated with the EDM NIR-I standard curve coating, which is specifically designed for use in the near-infrared (NIR) spectrum, covering the wavelength range of 600-1050nm. This coating enhances the lens's performance in the NIR region, making it ideal for applications such as thermal imaging, night vision, and spectroscopy.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens's inner and outer radii are 0mm, indicating a simple plano-convex geometry. The front surface radius of curvature (R1) is 155.04mm, and the back focal length (BFL) is 298.02mm.
