17-012 50mm Dia. N-SF6 Precision Aspheric Lens; EFL=30mm; NA=0.83 SWIR-Plus 900-1700nm

The 17-012 is a high-precision aspheric lens, designed and manufactured by Edmund Optics. This lens is characterized by its 50mm diameter and a numerical aperture (NA) of 0.83, making it suitable for use in the shortwave infrared (SWIR) range of 900-1700nm.

The lens is made from N-SF6 Schott, a material known for its excellent optical properties in the SWIR range. The aspheric design of the lens helps to reduce spherical aberration, thereby improving the 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 the light rays converge.

The lens features a high-quality coating, denoted as 'edm swirplus90017003', on both the front and back surfaces. This coating is designed to enhance the lens's performance in the SWIR range, providing improved transmission and reducing reflections.

The lens has a thickness of 7.35mm at the edge and 21.56mm at the center. The front surface of the lens has a radius of curvature (R1) of 24.156mm, while the back surface (R2) is flat. The lens's design includes a large inner radius and a small outer radius, which helps to minimize vignetting and improve the field of view.

In terms of its geometry, the lens has a base shape of a circle, with a diameter of 50mm. The front and back surfaces are defined by a series of polynomial coefficients, up to the fourth order, which help to shape the lens's aspheric profile.
