87-990 10mm Dia. UVFS Aspheric Lens; EFL=10mm; NA=0.5 NIR 600-1050nm
The 87-990 is a high-performance aspheric lens, boasting a 10mm diameter and a numerical aperture (NA) of 0.5, specifically designed for use in the near-infrared (NIR) spectrum, between 600 and 1050nm. This lens is sourced from Edmund Optics, a leading vendor known for its quality optical components.
The lens is made from UV-fused silica, a material with a high transmission range, making it ideal for use in the NIR spectrum. The aspheric design of the lens helps to reduce spherical aberration, a common issue in traditional spherical lenses, resulting in improved image quality and resolution.
The lens has an effective focal length (EFL) of 10mm, which, combined with its NA, provides a wide field of view and high light-gathering capability. The lens has a center thickness of 6mm and an edge thickness of 2.77mm, contributing to its robustness and durability.
The lens is coated with Edmund Optics' NIR coating, designed for the 600-1050nm range, which further enhances its performance in the NIR spectrum. This coating helps to reduce surface reflections, improving transmission and contrast.
