67-505-INK 12.0mm Dia. x 84.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-505-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 catering to wavelengths between 750nm and 1550nm.
The lens's geometry is characterized by its edge thickness of 1.91mm and center thickness of 2.4mm. It boasts an effective focal length (EFL) of 72mm, making it suitable for a variety of optical applications. The front surface of the lens has a radius of curvature of 37.21mm, while the back focal length (BFL) measures 70.42mm. The lens's inner and outer radii are both zero, indicating a uniform curvature.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The lens's front and back surfaces are coated with the EDM NIR-II STD CURVE coating, designed to enhance performance in the NIR II spectrum.
Please note that the lens's coating and material ID are subject to the vendor's specifications and may have variations. Always refer to the vendor's website or contact them directly for the most accurate and up-to-date information.
