The view angle of the lens is from 160-degree to 272-degree, the relatibe aperture D/F is 1/2 to 1/2.6, and the dimension of the target surface from 0.7 to 1.8 inches. It has the teatures of high brightness, high resolution, and clear image. It can be used for 1-20 meters in diameter hemispheric screen and super-hemisperical screen. If there are special requirements of the customers, we can design new lens for the needs of the customers.
Technology advangtage
The film (projection) fish-eye lens series have obtained 7 invention patents and 2 pratical new pattern patents. Only one lens can make the dome-screen movie come true.we provide good sevices. As our product is as good as other similar products, we can offer a better price to make it the best quality with a reasonable price. It can be used in the fields like: dome-screen cinema, astonomy teaching, digital earth, geofraphy query and teaching, amusement sites (pubilic house,ballroom), exhibition drumbeating, inaugurate and so on.
Monitoring panorama fish-eye lens series
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.
