◆ Telecentric Lens is that placed aperture
diaphragm on image space focal plane of optical system.
◆ When aperture diaphragm on image space
focal plane, even object distance changes and image distance changes, image
height doesn’t changes, then object size of measure will not change.
◆ Telecentric Lens is applied in industry precision measurement.
Distortion is very small. High-powered one can have no distortion.

Note:
1. The depth of field is the value of parsing images if you use 1/2" CCD camera and monitor of level 320 line.(imaging surface concessional confusion circumference: 40μm)
2. Resolution is the theory resolution of wavelength in 550nm.
3. The largest compatible CCD: 1/2"
4. Install dimension: C-mount, the whorl is 1 inch 32 button.
5. In the line of total magnification, “1/3"” is expressed CCD camera's specifications, “9"”、“14"” is expressed monitor's screen dimensions. “1/3"、9"” is expressed the total magnification of MTDY series Object Space Telecentric Lens in 1/3" CCD camera and 9" monitor.
