Photolithographic multispectral filters are precision-engineered optical filters that utilize a combination of coating techniques and photolithographic processes to create intricate thin-film patterns. The photolithographic process involves transferring geometric patterns from an optical mask to a substrate using UV light and light-sensitive chemicals, resulting in high-performance thin-film coatings that are applied in a sequence within patterned apertures.
