Color Filter and Micro Lens
Discover vibrant color images with our Color Filter Array (CFA), a key component for CCD and CMOS image sensors and LCOS microdisplays.
Embrace enhanced light gathering power and improved sensitivity with our micro-lens array (MLA) technology, designed to complement our CFA's image sensor and optimize visual experience.
Micro-lens Arrays
The CFA is formed directly on each phototransistor, and atop the CFA is a Micro-Lens Array. These small lens elements perform two functions for the image sensor: enhancing light gathering power and increasing the device sensitivity.
Color Filter Arrays
CFAs are a mixture of tiny color filters placed over the individual pixels of an image sensor. Although the phototransistor generates an electric signal once it receives light, it does not produce any color image since it reacts only to light and dark. The color filter allows each pixel of the sensor to respond to a specific color. Toppan CFAs have a reputation for pristine color reproduction and high-quality fabrication. We offer red, green, and blue (RGB) CFAs or cyan, magenta, yellow and green (CMYG) CFAs.
