16-984 30mm Dia. N-SF5 Precision Aspheric Lens; EFL=22.5mm; NA=0.66 NIR-Plus 600-1050nm

The 16-984 is a high-precision aspheric lens, boasting a 30mm diameter and a numerical aperture (NA) of 0.66. This lens is designed for use within the near-infrared spectrum, specifically between 600 and 1050nm. The lens is crafted from N-SF5 Schott, a material known for its excellent optical properties, making it ideal for a wide range of applications.

The lens features an effective focal length (EFL) of 22.5mm, which is a crucial factor in determining the lens's overall magnification and field of view. The inner and outer radii of the lens are 0, indicating a symmetrical design, which can contribute to improved image quality. The lens has a thickness of 6.62mm at the edge and 15mm at the center, providing structural integrity and stability.

The 16-984 lens is coated with Edmund Optics' NIR-Plus 600-1050nm coating on both the front and back surfaces. This coating is designed to enhance the lens's performance within the specified near-infrared spectrum, reducing unwanted reflections and increasing transmission.
