The 3-CCD / CMOS cameras are equipped with three image sensors, one for blue, red and green, three colors separated by a prism. A block of glass thicker than that used in a single CCD / CMOS camera is placed between the lens and the sensor. When the same objectives as those of simple CCD / CMOS cameras are used for 3 CCD / CMOS cameras, the performance of the camera may not be fully achieved due to the optical effect of color separation in the camera. This is why special lenses are needed for 3-CCD / CMOS cameras.
The TF4DA-8 lens has been designed to optimize the image quality of 3CCD / CMOS cameras.
Low distortion allows precise image input. Compact, light and robust, it supports various systems.
High color performance for 3CCD cameras, ideal for advanced surveillance applications.
