Abstract
A linear variable optical bandpass filter that is coated directly on an electronic device such as the detector array in a mobile smart phone by a combination of established optical modeling software and microlithography techniques to create a spectrometer in a mobile smart phone is disclosed.
Claims3
A method for applying is linear variable optical bandpass filter coating directly on a mobile smart phone detector array comprising:
- first X and Y coordinates of photosensitive areas of said mobile smart phone detector array wafer are determined from a top metal structure of said mobile smart phone detector array;
- and,
- then said X and Y coordinates combined with a desired linear variable optical bandpass coating dispersion across said photosensitive areas of said mobile smart phone detector array are fed into an optical modeling software program using a coating application source as a light source.
