Support 1.2" type large image sensor.
Fujinon CF-ZA-1S series supports large high-resolution sensor of 1.2″ type with 2.74μm pixel pitch (equivalent to 24 mega-pixel) or 1.1″ type with 2.5µm pixel pitch (equivalent to 23 mega-pixel). The relative illumination reaches up to above 90%*1, and a clear image can be obtained from the image center to the peripheral area.

Relative illumination reaches up to above 90%*2
In general, the illumination of the peripheral area of the image is determined by “relative illumination” and “chief ray angle (CRA)”. CF-ZA-1S series adopts the original optical design of Fuji film with the relative illumination up to above 90%*2 (lens monomer) and supports 1.2″ type large sensor, and restrains CRA below 5°. Because the two are relatively balanced to each other, the clear and bright image can be obtained from the peripheral area.

In general, in order to improve the difference between light and shade in the center and peripheral area, the correction treatment of the image can only highlight the “noise” but cannot obtain good image, while CF-ZA-1S series has no need to correct illumination and realizes uniform illumination including the peripheral area, thus the high-quality image with low noise can be obtained. It is most applicable to the inspection demanding higher reliability.
