CF-ZA-1S Series

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 1.1" 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.

• * 2 When the F4 F-Stop is used more frequently by users.

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.

By adopting internal mechanical focus, the overall length of lens will not change when focused Provided with 3 positioning holes for fixation of the Iris and focusing on lens body and the positioning hole can be selected according to setting conditions.

Having a indication sign on the lens that shows the optimal focus position when the subject is 50cm apart helps you to detect the flange back dislocation effectively.

The "anti-separation structure" is implemented on the knob of the Iris and focusing screw even if it is shaken violently, the screw will not fall off.

When manufactured, the optical performance results of each lens are managed by the factory.
As the tool for FUJIFILM quality management, the lens cone of each lens is printed with QR code.
