American Theia sl183a 5 megapixel wide angle distortion free and distortion free industrial zoom lens

SL183 zoom ultra wide distortion free 5 megapixel lens
Introduction of ultra wide angle non fisheye distortion megapixel lens
Theia is the first company in the world to launch high-quality ultra wide angle linear optical lens for security video surveillance and machine vision market. The innovative linear optical technology of Theia company has obtained a number of American patents and awards, which makes the horizontal angle of view of the ultra wide angle lens reach 135 ° and the image distortion is extremely low (no "fisheye distortion") and the image edge remains high definition.
The main features of Theia high quality lens are as follows:
1. Patented linear optical technology: very low image distortion at maximum resolution; lens optical image correction (without software correction)
2. Ultra wide angle (the maximum horizontal field of view angle can reach 135 °): make the range of monitoring scene wider. It is very suitable for video monitoring in large places, such as square, parking lot, traffic and so on
3. Support the application requirements of megapixel resolution
4. Pan focus: there is no need to adjust the lens, and the far and near scenes are focused clearly, which completely solves the defect of not taking into account the far and near clarity of the camera
5. Sy110 series lens supports day and night camera (IR correction)
6. Support CS or C-ring lens interface
Linear optical technology
The patented linear optics technology provides an ultra wide viewing angle of 116 ° to 77 ° which enables fewer cameras to be used in a larger monitoring range
The easyszoom feature allows users to optimize the viewing angle with minimal focus
IR correction is provided to support day and night cameras
