87-992 12.5mm Dia. UVFS Aspheric Lens; EFL=12.5mm; NA=0.5 NIR 600-1050nm

The 87-992 is a high-performance aspheric lens, boasting a 12.5mm 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 provider of optical components.

The lens is crafted from HPFS7980, a type of ultra-low expansion (ULE) fused silica, which offers excellent thermal stability and optical performance. The aspheric design of the lens helps to minimize spherical aberration, providing superior image quality over traditional spherical lenses.

The lens has an effective focal length (EFL) of 12.5mm, ensuring a compact and efficient optical system. The center thickness of the lens is 6mm, while the edge thickness is 1.98mm, providing robustness and durability. The front and back surfaces of the lens are coated with EDM NIR 600-1050nm coating, enhancing its transmission in the NIR spectrum.

This lens is an ideal choice for applications that require high-resolution imaging in the NIR spectrum, such as night vision systems, scientific research, and industrial inspection. With its superior optical performance, thermal stability, and robust design, the 87-992 is a reliable and versatile component for a wide range of optical systems.
