Design based on Galilean (Parallel) Optical System, a Coaxial Illumination, Polarization System, Iris or Spectrophotometer can be attached.

A Coaxial Illumination, Polarization System, Iris Cross Hair Reticle can be attached.
The "full field view" design, can add on the eyepieces observation system.
Semi-Plan Achromatic Objective, Can be mount the Infinity Corrected Objective Lens.
"Infinite and long working distance" metallurgical objective lens can be connected.
Complete of objective lens, coupler and CCD camera system.

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
