16-985 30mm Dia. N-SF6 Precision Aspheric Lens; EFL=17.5mm; NA=0.86 NIR-Plus 600-1050nm
The 16-985 is a high-precision aspheric lens, boasting a 30mm diameter and a numerical aperture (NA) of 0.86. This lens is designed for use within the near-infrared spectrum, specifically between 600 and 1050nm. The lens is crafted from N-SF6 Schott, a material known for its excellent optical properties.
The lens features an effective focal length (EFL) of 17.5mm, making it suitable for a variety of applications. The aspheric design of the lens helps to reduce spherical aberration, thereby improving image quality. The lens has a high NA, which allows for a larger light-gathering capacity, enhancing its performance in low-light conditions.
The 16-985 lens comes with a coating of EDM NIR-Plus 600-1050nm on both the front and back surfaces. This coating is designed to enhance the lens's performance within the specified near-infrared spectrum, improving transmission and reducing reflection.
The lens has a thickness of 4.17mm at the edge and 13mm at the center. The inner and outer radii are not specified, indicating that they are not critical to the lens's performance. The front and back focal lengths are 2.7018881e-05mm and -5.4438834e-09mm respectively, while the conic constant (k1) is -1.173125.
