21-945 50mm Dia. UVFS Aspheric Lens; EFL=100mm; NA=0.23 UV-VIS 250-700nm
The 21-945 is a high-performance aspheric lens, designed and manufactured by Edmund Optics. This lens is characterized by its 50mm diameter and a numerical aperture (NA) of 0.23, making it suitable for a wide range of applications. The lens is made from UV-fused silica, a material known for its excellent transparency across the UV-VIS spectrum, spanning from 250 to 700nm.
The lens features a focal length (EFL) of 100mm, which is a common choice for many optical systems due to its versatility. The aspheric design of the lens helps to reduce spherical aberration, a common issue in traditional spherical lenses, thereby improving the overall image quality. The lens has a high damage threshold, making it suitable for high-power applications.
The 21-945 comes with standard UV-VIS coatings on both the front and back surfaces, further enhancing its transmission capabilities. The coating is designed to provide high transmission and low reflectance across the UV-VIS spectrum.
