Design and fabricating of visible/infrared dual-band microfilter array
Integrated visible/infrared dual-band filter array is the key component of compact, lightweight, rigid miniature dual-band CCD sensing system. Interference cut-off filter array and interference absorbing filter array have been designed for infrared and visible pass band respectively. A simple, effective and compatible with high temperature deposition process lift-off technique for striping thick infrared film was investigated. Integrating photolithography, ion beam assisted electron beam physical vapor deposition and improved lift-off process, dual-band microfilter array with good performance was fabricated on the same sapphire substrate consecutively. Details of design and fabricating procedure are elucidated, and experimental results are presented.
