22-759 15mm Dia. N-SF6 Precision Aspheric Lens; EFL=9mm; NA=0.83 SWIR-Plus 900-1700nm

The 22-759 is a high-precision aspheric lens, 15mm in diameter, with a numerical aperture (NA) of 0.83, specifically designed for the short-wave infrared (SWIR) spectrum, covering the 900-1700nm range. This lens is sourced from Edmund Optics, a leading vendor in the optical industry.

The lens is made from N-SF6 Schott, a material known for its excellent transmission properties in the SWIR range. It features a high NA, which allows for a larger light-gathering capacity, resulting in a brighter image. The aspheric design of the lens helps to reduce spherical aberration, improving the overall image quality.

The lens has an effective focal length (EFL) of 9mm, making it suitable for applications that require a wide field of view and high resolution. The lens thickness at the edge is 5.28mm, while the center thickness is 9.7mm, providing structural rigidity and minimizing optical distortions.

The lens is coated with Edmund Optics' SWIRPlus90017003 coating on both the front and back surfaces. This coating enhances the lens's transmission in the SWIR range, reducing reflection losses and increasing the overall system efficiency.

The item data provides detailed geometry information, including the inner and outer radii, diameter, thickness edge, EFL, radii of curvature, conic constant, and aspheric coefficients. This data can be used to precisely model the lens's optical performance in simulation software.
