Contact Image Sensors (CIS)

Wide Scanning CIS

Wide Scanning Contact Image Sensors are incorporated into scanners for the conversion of printed text and images to digital data. In addition to a wide range of other products in diverse fields that require high-precision scanning. Such as banknote readers and flaw detection sensors for industrial equipment. Thanks to our flexible response to expanding markets and diversifying customer needs, our CIS enjoys strong popularity in the global market.

Devices Including Image Sensors

For instance, in the contact image sensor scanning method, the wide-format document reflects the light from the three-color LEDs. The CIS sensor within the large format scanner receives the reflected light and performs the scan. Also known as the “contact image sensor method” because the LEDs, lens, and sensor are all combined into a single component. CIS scanning is typically used for detailed documents such as maps and government documents due to the scanner’s capability to duplicate fine lines and small types.

Wide Scanning (CIS) is an image reading sensor using LEDs as the light source with integrated lenses and sensor ICs for imaging. Our CIS is used as image reading devices in a wide variety of products since it is easily integrated into the products.
