CF-ZA-1S Series

"4D High Resolution" lenses

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.

Main features

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.

* 2 In the case of 1.1" type with F4.0

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.

＜Real image without correction treatment＞

This is an image of a character chart taken with a camera and lens set that is equipped with a global shutter CMOS sensor. With a standard lens, the special structure of the global shutter CMOS sensor prevents sufficient light from reaching the light-receiving surface, causing the image periphery to become dark and making the characters difficult to read.

Original high-resolution performance of Fujinon lens "4D High Resolution"

"4D High Resolution" keeps uniform high resolution from the image center to peripheral area and can restrain the decline of resolution caused by shooting
distance or F-Stop, which is the original high-resolution performance of Fujinon lens.
Therefore, the high-resolution image can be obtained under various setting and photographic conditions.

Supporting 1.2" type sensor and 2.74μm pixel pitch (equivalent to 24 mega-pixel) makes the most use of camera performance.
Especially, it is most applicable to IMX530 (1.2"type), IMX253 (1.1" type), IMX255 (1" type) and IMX183 (1"type).

Restrain unilateral bokeh and single flaw through high-precision assembly technology and original detector.

Adopt the FUJIFILM's original mechanical structure design of "vibration-resistance and impact-resistance"

A photograph of a camera and lens mounted on a vibration machine to test for vibration resistance

Conduct strict vibration test according to JIS C 60068-2-6^*3 and keep high resolution prior to and after the test.

Under the circumstance that the robot vision and 3D scanning, etc.
are hit, even by maximum a 10G^*4 hit, the optical axis variation
(picture dislocation) is only below 10μm.

Without excessive use of glue and by adoption of the company's
original mechanical structure^*5, the degradation caused by humidity,
heat and long lasting will not occur.

The performance of "vibration-resistance and impact-resistance" is secured even though the iris can be adjusted. These features makes operation easier.

Compact design of outer diameter φ39㎜ (CF8ZA-1S: outer diameter φ54㎜) contributes to saving space.

High operability / Unified design

The lens uses a mechanical design that does not change the overall length of the lens even when focusing. The lens length is almost the same (67-68mm) across the 6 models, and the focus and iris controls are the same across all models. The focus rotation angle is also large, making it easy to adjust the best focus even with high-resolution sensors.

High convenience

1. Drop-prevention screw
The mechanical design of the screws prevents them from falling from the screw hole. Even in environments with a lot of vibration, you can use the screws reliably without worrying about the screws falling off.

* Only supported by the CF-ZA-1S series.

2. Headless screw
The lens barrel has three fixed holes each for the iris (aperture) and focus, so users can choose the best fixed hole to suit their installation conditions. By replacing the screw with the included headless screw, the protruding screws can be eliminated.

* Six headless screws are included in the set.

High reliability / Traceability

The optical performance of each lens is fully managed at the factory. As a sign of this management, a 2D code is printed on the lens barrel label.
