67-496 12.0mm Dia. x 20.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex lens, type 67-496, with a diameter of 12.0mm and a focal length of 20.0mm, specifically designed for use in the near-infrared (NIR) spectrum. The lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock.
The lens is made from the high-quality material n-BK7 Schott, a borosilicate glass known for its excellent optical properties. The lens features a spherical shape, with a front radius (R1) of 7.75mm and a back focal length (BFL) of 12.03mm. The lens has an effective focal length (EFL) of 15mm, making it suitable for a wide range of optical applications.
The lens is coated with the EDM NIR-II std curve on both the front and back surfaces. This coating enhances its performance in the NIR spectrum, specifically between 750nm and 1550nm, making it ideal for applications such as night vision, thermal imaging, and spectral analysis.
The lens has a thickness of 1.66mm at the edge and 4.5mm at the center. Despite its compact size, it delivers impressive optical performance, making it a popular choice for designers and engineers working on compact optical systems.
