fisheyelinjset
Fisheyelinjset is a term that emerged in the late 2000s within the field of visual technology and photography. It refers to a specific type of lens filter engineered to produce a pronounced fisheye effect while minimizing distortion and aberrations commonly associated with such wide‑angle optics. The name combines the words “fisheye,” describing the curvilinear view it creates, and “jset,” a coined suffix derived from the acronym JSET, which stands for “Junction Set” and originally referred to a network of optical components linking the lens to the sensor. In contemporary use, fisheyelinjset lenses are chosen for applications that require panoramic capture without the extreme curvature seen in conventional fisheye lenses, such as security cameras, virtual reality headsets, and cinematic special effects.
The development of fisheyelinjset lenses involved collaboration between academic researchers in optical engineering and commercial manufacturers
