16-266 10mm Dia. S-LAH64 NIR Aspheric Lens; EFL=8mm; NA=0.63 VIS Plus 350-700nm

This is a high-quality 10mm diameter aspheric lens, designed for use in the near-infrared (NIR) spectrum with a wavelength of 780nm. The lens is sourced from Edmund Optics and is identified by the catalog number 16-266. It is available for purchase online, with the weblink provided in the item data indicating that it is currently in stock.

The lens is made from S-LAH64 material, a type of optical glass developed by Ohara. This material is known for its excellent transmission properties in the NIR spectrum, making it ideal for applications such as optical imaging, spectroscopy, and beam shaping in this wavelength range.

The lens features a high numerical aperture (NA) of 0.63, which allows for a wide angle of view and high light-gathering capability. The effective focal length (EFL) of the lens is 8mm, which, combined with its diameter, gives it a relatively compact form factor.

The lens is coated with Edmund Optics' VIS Plus 350-700nm coating on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and increase transmission in the visible (VIS) and NIR spectra, enhancing the overall performance of the lens.

The geometry of the lens includes a range of parameters that define its shape and optical properties. These include the inner and outer radii, thickness at the edge and center, and the back focal length (BFL). The lens also features a aspheric surface, which helps to reduce spherical aberration and improve the overall image quality.
