Mosaic Filter

Name: Mosaic Filter
Brand: ECOPTIK INDUSTRIAL PTE.LTD.

Mosaic filter is a miniature color filter array that covers an image sensor. Let each pixel sense only one color, and then calculate the full-color image through algorithm interpolation. It can achieve high-quality color digital imaging with the lowest cost and simplest structure.

Features of Mosaic Filter

Pixel level Mosaic filter, referring to the color filter RGB channel arrangement, multiple micrometer level spectral channels are arranged into a spectral period according to a certain law, and multiple spectral periods are arranged on the filter surface in a Mosaic way. The physical size of the filter can be determined according to the pixel size of the detector so that the spectral channel and detector pixel can be aligned one by one.
