84-335 15mm Dia. UVFS Aspheric Lens; EFL=15mm; NA=0.5 UV-VIS 250-700nm

The 84-335 is a high-performance aspheric lens, 15mm in diameter, designed for use in the ultraviolet to visible light spectrum, specifically between 250 and 700 nanometers. This lens, sourced from Edmund Optics, boasts a numerical aperture (NA) of 0.5, indicating a wide acceptance angle and excellent light-gathering capabilities.

The lens is made from UV-grade fused silica, a material known for its exceptional transparency and resistance to thermal shock. This makes it an ideal choice for applications that require high-fidelity imaging in challenging environments. The lens features a high-quality UV-VIS coating, enhancing its transmission capabilities and further boosting its performance in the specified wavelength range.

The 84-335's geometry is meticulously designed, with an effective focal length (EFL) of 15mm and a back focal length (BFL) of 10.029mm. The lens has a center thickness of 7.25mm and an edge thickness of 2.43mm, providing robustness and durability. The aspheric design of the lens helps to correct spherical aberration, a common issue in traditional spherical lenses, resulting in superior image quality.
