1、Zoom ratio objective：1:6
2、Objective zoom range：0.7X - 4.5X
3、Use 1/3" CCD camera
Optic magnification=Objective magnification x Coupler magnification
Electronic magnification = Diagonal size of monitor/Diagonal size of CCD pickup device
Total magnification=Optic magnification x Electronic magnification
For example: suppose that the zoom range of a zoom body is 0.7~4.5, coupler magnification is 0.3, objective magnification is 0.3, using 1/3” CCD camera and 14” monitor, then the method to calculate the total magnification is:
Min magnification: 0.7x 0.3 x 0.3 x (14 x 25.4/6)=3.73
Max magnification: 4.5 x 0.3 x 0.3 x (14 x 25.4/6)=24
Field of view (FOV) = Diagonal size of CCD pickup device / (Objective magnification x Coupler magnification x zoom body magnification)
The method to calculate the FOV in the above example is:
Max FOV: 6/(0.3 x 0.3 x 0.7)=95
Min FOV: 6/(0.3 x 0.3 x 4.5)=15
Accessories:
Objective: 0.3x / 0.5x / 0.75x / 1x / 1.5x / 2x
Video Coupler:0.3x / 0.5x / 0.75x /1x / 1.5x / 2x
