16-282 18mm Dia. S-LAH64 NIR Aspheric Lens; EFL=15mm; NA=0.6 NIR-Plus 600-1050nm

The 16-282 is an 18mm diameter aspheric lens, designed for use within the near-infrared (NIR) spectrum, specifically between 600 and 1050nm. This lens is sourced from Edmund Optics and is part of their extensive catalog of optical elements.

The lens is constructed from S-LAH64, a material developed by Ohara, and features a high numerical aperture (NA) of 0.6. This high NA allows for a greater light-gathering capability, making this lens ideal for applications that require high resolution and contrast.

The lens has an effective focal length (EFL) of 15mm, which is the distance from the lens's principal point to the image plane when the lens is focused at infinity. This EFL, combined with the lens's high NA, makes it suitable for use in applications such as optical imaging, beam shaping, and laser focusing.

The 16-282 features an aspheric design, which allows for improved optical performance compared to traditional spherical lenses. This design reduces spherical aberration, coma, and other optical aberrations, resulting in a clearer, sharper image.

The lens is coated with Edmund Optics' NIR-Plus 600-1050nm coating on both the front and back surfaces. This coating enhances the lens's transmission within the NIR spectrum, reducing reflection and increasing the amount of light that passes through the lens.
