Compensation Filters For Visualization Of White Leds Through The Ceramic Glass In Induction Cooktops

White LEDs visualization in induction cooktops is hindered by the non-uniformity in wavelength of the transmission of the ceramic glass used as the cooking surface, as it modifies the chromaticity of the LEDs. In this work, a compensation filter is developed by thin-film interference filter deposition techniques, which has a transmission spectrum that allows for the preservation of the light source intrinsic chromaticity. This permits a perfect visualization of white LEDs across ceramic glasses.
