67-516 15.0mm Dia. x 18.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex lens, type 67-516, with a diameter of 15.0mm and a focal length of 18.0mm, specifically designed for use in the Near-Infrared II (NIR II) spectrum, covering the wavelength range of 750-1550nm. The lens is sourced from the reputable vendor, Edmund Optics.
The lens is made of the high-quality material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, making it suitable for various applications. The lens features a spherical shape, with a front radius (R1) of 26.25mm and a back focal length (BFL) of 49.15mm.
The lens's geometry includes an edge thickness of 1.72mm and a center thickness of 2.5mm, providing robustness and durability. The effective focal length (EFL) is 50.8mm, which is crucial for determining the lens's focusing capabilities.
The lens is coated with the EDM NIR-II STD curve on both the front and back surfaces, enhancing its performance in the NIR II spectrum. This coating ensures high transmission and low reflection, making it ideal for applications requiring minimal light loss and high-quality image transmission.
