84-340 50mm Dia. UVFS Aspheric Lens; EFL=40mm; NA=0.63 UV-VIS 250-700nm

The 84-340 is a high-performance aspheric lens, designed and manufactured by Edmund Optics. This lens boasts a 50mm diameter and a numerical aperture (NA) of 0.63, 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 systems.

The lens features a unique aspheric design, which helps to minimize spherical aberration and distortion. This design is particularly beneficial in systems requiring high resolution and accuracy, such as imaging or metrology applications.

The 84-340 lens has an effective focal length (EFL) of 40mm, providing a moderate magnification factor. This EFL, combined with the lens's large NA, allows for a wide field of view while maintaining a high level of image detail.

The lens is coated with a standard UV-VIS coating, which further enhances its light transmission capabilities. This coating is designed to reduce surface reflections and increase the lens's overall efficiency.
