87-987 12.5mm Dia. UVFS Aspheric Lens; EFL=10mm; NA=0.63 VIS 425-675nm
The 87-987 is a high-quality aspheric lens, 12.5mm in diameter, manufactured by Edmund Optics. This lens is made from UV fused silica (syn hpfs7980 corning), a material known for its excellent transparency and durability in the ultraviolet and visible spectrum. The lens's design includes a 10mm effective focal length (EFL), making it suitable for a wide range of optical applications.
The lens boasts a high numerical aperture (NA) of 0.63, which allows for a larger light-gathering capability and increased resolution. The aspheric shape of the lens helps to reduce spherical aberration, a common issue in traditional spherical lenses, resulting in improved image quality and clarity.
The 87-987 lens is coated with a broadband anti-reflection coating, specifically designed for the visible spectrum (425-675nm). This coating reduces surface reflections, enhancing the transmission of light and improving the overall performance of the lens.
The lens has a thickness of 2.03mm at the edge and 8mm at the center. The front and back surfaces of the lens are equally coated, ensuring optimal performance from both sides. The lens is currently in stock and available for immediate purchase through the provided weblink.
