The engineers and technicians of Qinhuangdao Audio-visual Machinery Research Institute, put all their heart and soul on the researches and then develop the new series of fish-eye lenses using for monitoring. The target surface size of these series of lenses is 1/3 inches for CCD sensors, whose relative dperture ranges fromF/1.4 to F/16, angle of view from 180-degree to 320-degree. These series of lenses have the unique characteristics in their high resolving power and naturalistical color rendition, and their inspection standard fits the latest national standards of film-video image.
These series of lenses have a bright future in the areas such as bank vaults, treasury, question bank of school, drug storage and endoscopic of hospital, channe measurement, panoramic monitoring. And they can particularly be used in the no blind spot, and 24 hours duty environment without inerruption.
Features of fish-eye lens compared with traditional monitoring lens
1. Only one lens can achieve 180-degree wide-angle omnibearing monitoring with no blind spot effectively.
2. Simple circuit system as well as resource saving.
3. Less work for the monitoring staffs.
4. No rotating stations bring an important advance in service life.
