16-276 50mm Dia. S-LAH64 NIR Aspheric Lens; EFL=40mm; NA=0.63 VIS Plus 350-700nm

The 16-276 50mm Dia. S-LAH64 NIR Aspheric Lens is a high-quality optical component designed for use in the near-infrared (NIR) spectrum, specifically within the wavelength range of 350-700nm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for purchase through their online catalog.

The lens features a base shape of a circle, with a diameter of 50mm. It has a thickness of 4.9mm at the edge and a center thickness of 15.5mm. The effective focal length (EFL) of this lens is 40mm, making it suitable for a variety of optical applications. The lens's design includes an inner radius of 0mm and an outer radius of 0mm.

The lens's geometry is defined by its aspheric shape, with a first radius of curvature (R1) of 31.075mm and a second radius of curvature (R2) of 0mm. The back focal length (BFL) is 31.28mm. The lens's numerical aperture (NA) is 0.63, indicating a wide acceptance angle and high light-gathering capability.

The lens is made from S-LAH64 material, a type of optical glass produced by Ohara. This material is known for its excellent transmission properties in the NIR spectrum. The lens is coated with Edmund Optics' VIS Plus 350-700nm coating on both the front and back surfaces, further enhancing its performance in the specified wavelength range.
