This invention relates to a superlens, an endoscope, and their applications. The superlens operates with a wavelength range of 780nm-850nm. Before surgery, patients are injected with a clinically approved indocyanine green solution, which acts as a fluorescent material entering the gastrointestinal mucosa. For the superlens of this invention, with its operating wavelength range of 780nm-850nm, after the 780nm laser output from the fiber bundle is focused onto the gastrointestinal mucosa by the superlens, the indocyanine green emits a fluorescence signal with a peak wavelength of 830nm and a receiving bandwidth of 810nm-850nm. This fluorescence signal returns to the fiber bundle via the superlens and is transmitted to an image processor for imaging. The fluorescence imaging mode employed by the endoscope of this invention enables high-resolution, high-contrast imaging of the gastrointestinal mucosa, thereby allowing for faster and more accurate identification of the location and nature of early-stage and precancerous lesions in the gastrointestinal mucosa during gastroscopy and colonoscopy, improving biopsy accuracy and efficiency while reducing the workload of biopsy procedures.
