16-270 18mm Dia. S-LAH64 NIR Aspheric Lens; EFL=15mm; NA=0.6 VIS Plus 350-700nm

The 16-270 18mm Dia. S-LAH64 NIR Aspheric Lens is a high-quality optical component designed for use in the visible and near-infrared spectrum, specifically catering to the 350-700nm range. This lens is sourced from the renowned optical vendor, Edmund Optics, and boasts a catalog number of 16-270.

The lens is characterized by its aspheric design, which is a type of lens profile that deviates from the simple spherical shape. This design allows for improved optical performance, particularly in terms of reducing spherical aberration and distortion. The base shape of the lens is circular, contributing to its wide angle of view and making it suitable for a variety of applications.

The lens is made from S-LAH64, a type of optical glass developed by Ohara. This material is known for its excellent transmittance in the near-infrared region, making it ideal for use in NIR applications. The lens has a diameter of 18mm and a thickness of 2.55mm at the edge, ensuring durability and robustness.

The lens features an effective focal length (EFL) of 15mm, which is the distance from the center of the lens to the focal point when the lens is focused at infinity. This EFL makes the lens suitable for wide-angle applications. The lens also has a numerical aperture (NA) of 0.6, which is a measure of the lens' light-gathering ability and resolution.

The lens is coated with Edmund Optics' VIS Plus 350-700nm coating on both the front and back surfaces. This coating enhances the lens' performance in the specified wavelength range, improving its transmittance and reducing reflections.
