17-009 40mm Dia. N-SF5 Precision Aspheric Lens; EFL=30mm; NA=0.66 SWIR-Plus 900-1700nm

The 17-009 is a high-precision aspheric lens, designed and manufactured by Edmund Optics. This lens is characterized by its 40mm diameter and a numerical aperture (NA) of 0.66, making it suitable for use in a wide range of applications. The lens is made from N-SF5 Schott, a material known for its excellent optical properties, particularly in the shortwave infrared (SWIR) region.

The lens has an effective focal length (EFL) of 30mm, which is the distance from the lens's principal point to the image plane when the lens is focused at infinity. This EFL, combined with the lens's high NA, allows for a wide field of view and high light-gathering capability.

The 17-009 lens features an aspheric surface, which is a type of surface that deviates from a spherical shape. This design allows for the correction of spherical aberration, a common optical problem that can lead to distorted or blurry images. The lens's geometry includes a 20.182mm radius of curvature (R1) and a 0mm radius of curvature (R2), contributing to its high optical performance.

The lens is coated with Edmund Optics' SWIR-Plus 900-1700nm coating, which is specifically designed to enhance the lens's performance in the SWIR region. This coating helps to reduce reflection and increase transmission, improving the overall image quality.
