84-334 15mm Dia. UVFS Aspheric Lens; EFL=12.5mm; NA=0.6 UV-VIS 250-700nm
The 84-334 is a high-performance aspheric lens, designed and manufactured by Edmund Optics. This lens boasts a 15mm diameter and a numerical aperture (NA) of 0.6, making it a versatile choice for a wide range of optical applications.
The lens is crafted from UV-grade fused silica, a material known for its exceptional transparency across the UV-VIS spectrum (250-700nm). This material choice ensures high-fidelity light transmission, making the lens ideal for use in UV-VIS applications.
The lens features an effective focal length (EFL) of 12.5mm, a key parameter that determines the lens's magnification capabilities. This EFL, combined with the lens's NA, allows for a generous depth of field and high resolution, making it suitable for imaging applications.
The lens's aspheric design is a significant advantage. Unlike traditional spherical lenses, aspheric lenses can correct spherical aberration, a common issue that can degrade image quality. This design ensures that the lens delivers sharp, distortion-free images, even at wide apertures.
The lens is coated with a standard UV-VIS coating, which further enhances its light transmission capabilities. This coating reduces surface reflections, increasing the amount of light that passes through the lens.
