16-272 25mm Dia. S-LAH64 NIR Aspheric Lens; EFL=20mm; NA=0.63 VIS Plus 350-700nm

The 16-272 is a high-quality aspheric lens offered by Edmund Optics, designed for use in the near-infrared (NIR) spectrum with a wavelength of 780nm. This lens is constructed from S-LAH64 material, a type of optical glass developed by Ohara, and features a precision aspheric surface to minimize spherical aberration and distortion.

The lens has a diameter of 25mm and a numerical aperture (NA) of 0.63, providing a high light-gathering capability and a wide field of view. The effective focal length (EFL) is 20mm, making it suitable for applications that require a compact, high-performance lens. The lens is coated with Edmund Optics' VIS Plus 350-700nm coating, which enhances its transmission in the visible and NIR spectra.

The lens geometry includes a center thickness of 7.6mm and an edge thickness of 2.3mm, providing robustness and durability. The front and back surfaces of the lens are coated with the same VIS Plus 350-700nm coating to ensure high transmission and low reflection across the entire spectral range.

This lens is available for purchase through the Edmund Optics website, and the link provided is valid and indicates that the lens is in stock. With its high-quality construction, advanced coating, and precise geometry, the 16-272 is an excellent choice for a wide range of NIR imaging and measurement applications.
