Panasonic’s new Micro Color Splitters are an alter­na­tive to these color fil­ters. Instead of fil­ter­ing out light, the split­ters act as tiny prisms to split the incom­ing light into red, green, and blue light onto mul­ti­ple pix­els on the sen­sor. Color infor­ma­tion is still cap­tured, just as with CFAs, but a the­o­ret­i­cal 100% of light is directed onto the sensor.

Most new tech­nolo­gies fail to make it to mar­ket because they are not com­pat­i­ble with today’s under­ly­ing man­u­fac­tur­ing infra­struc­ture or it takes too long or costs too much to change it. I believe Panasonic’s Micro Color Splitters have a good chance of being inte­grated into next gen­er­a­tion cam­eras and smart­phones soon because these can sim­ply replace color fil­ter arrays in exist­ing image sen­sor solu­tions. I’m look­ing for­ward to bet­ter low light photography.
