17-003 30mm Dia. N-SF5 Precision Aspheric Lens; EFL=30mm; NA=0.5 SWIR-Plus 900-1700nm

The 17-003 is a high-precision aspheric lens, designed and manufactured by Edmund Optics, a leading provider of optical components. This lens boasts a 30mm diameter and a numerical aperture (NA) of 0.5, making it suitable for use in the short-wave infrared (SWIR) spectrum, specifically between 900 and 1700nm.

The lens is made from N-SF5 Schott, a high-refractive index glass that is known for its excellent transmission properties in the SWIR range. The aspheric design of the lens helps to reduce spherical aberration, a common issue in traditional lenses, thereby improving the overall image quality.

The lens has an effective focal length (EFL) of 30mm, which is the distance from the lens's optical center to the point at which light rays converge. This EFL, combined with the lens's NA, provides a wide field of view and high light-gathering capability, making it ideal for a variety of applications, including imaging, spectroscopy, and beam shaping.

The lens is coated with Edmund Optics' SWIR-Plus coating, which is specifically designed for use in the SWIR range. This coating helps to enhance the lens's transmission properties, reducing losses due to reflection and improving the overall efficiency of the system.

The lens has a thickness of 6.59mm at the edge and 12.5mm at the center. The front and back surfaces of the lens are coated with the same SWIR-Plus coating, ensuring optimal performance from both sides.
