33-957 25mm Dia. UVFS Aspheric Lens; EFL=17.5mm; NA=0.69 UV-VIS 250-700nm
The 33-957 is a high-performance aspheric lens, designed and manufactured by Edmund Optics. This lens boasts a 25mm diameter and a numerical aperture (NA) of 0.69, making it a versatile choice for a wide range of optical applications. The lens is constructed from UV fused silica, a material known for its excellent transparency across the UV-VIS spectrum, from 250 to 700nm.
The lens features a focal length of 17.5mm, as indicated by its effective focal length (EFL). This, combined with its high NA, allows for a wide field of view and high light-gathering capability. The lens also has a high refractive index, which contributes to its compact size and excellent image quality.
The 33-957 lens features an aspheric design, which helps to correct spherical aberration and distortion, common issues in traditional spherical lenses. This design ensures that the lens delivers sharp, clear images, even at the edges of the field of view.
The lens is coated with a standard UV-VIS coating, which enhances its transmission across the UV-VIS spectrum. This coating also provides protection against environmental factors, such as dust and moisture, thereby increasing the lens's durability and lifespan.
