87-979 12.5mm Dia. UVFS Aspheric Lens; EFL=10mm; NA=0.63 UV 250-425nm

This is a high-quality aspheric lens from Edmund Optics, with the catalog number 87-979. It is designed for use in the ultraviolet (UV) spectrum, specifically for wavelengths between 250 and 425 nanometers. The lens is made from UV fused silica, a material known for its excellent transparency in the UV range.

The lens has a diameter of 12.5mm and a numerical aperture (NA) of 0.63, indicating a wide acceptance angle and high light-gathering capability. The effective focal length (EFL) is 10mm, making it suitable for use in moderate to high magnification applications. The lens has a double-sided anti-reflection coating, optimized for the UV range, which reduces surface reflections and increases transmission.

The aspheric design of the lens helps to correct spherical aberration, a common optical problem that can lead to distorted or blurry images. The lens has a very short focal length for its diameter, which is achieved through the aspheric shape. This makes it ideal for use in compact optical systems where space is at a premium.

The lens is available for purchase directly from the Edmund Optics website, and at the time of data collection, it was in stock. For more detailed specifications and purchasing information, please refer to the provided weblink.
