87-989 10mm Dia. UVFS Aspheric Lens; EFL=8mm; NA=0.63 NIR 600-1050nm
The 87-989 is a high-performance aspheric lens, boasting a 10mm diameter and a numerical aperture (NA) of 0.63. This lens is designed for use in the near-infrared (NIR) spectrum, specifically between 600 and 1050 nanometers.
The lens is crafted from UV fused silica, a material known for its excellent transparency in the ultraviolet, visible, and infrared spectra. This makes the 87-989 a versatile choice for a wide range of optical applications.
The aspheric design of the lens helps to correct spherical aberration, a common issue in traditional spherical lenses. This results in improved image quality, particularly over larger apertures and fields of view.
The lens features an effective focal length (EFL) of 8mm, making it suitable for use in moderate telephoto applications. The edge thickness of the lens is 3.05mm, while the center thickness is 8mm, providing robustness and durability.
The 87-989 is coated with Edmund Optics' NIR coating, which is designed to enhance transmission in the NIR spectrum. This coating is applied to both the front and back surfaces of the lens, ensuring optimal performance.
