The Narrow-Band Imaging (NBI) technique allows the detection of lesions not identified with white light. Medical studies revealed that the wavelengths of 415 nm and 540 nm of the electromagnetic spectrum correspond to the peaks of hemoglobin absorptions band. The wavelength of 415 nm is located in the blue region of the electromagnetic spectrum, allowing the visualization enhancement of superficial veins. Moreover, the wavelength of 540 nm is located in the green region of the spectrum, and it is related to the visualization of sub-epithelial vessels. Initially, this work aims the design, simulation, fabrication (as well as stablish all the ideal settings for the depositions) and characterization of optical filters for the wavelength around...
