The near-infrared imaging channel constitutes a crucial component of the multichannel high-resolution imaging system of the New Vacuum Solar Telescope(NVST).We have successfully achieved high-resolution,narrowband imaging of the chromosphere using HeI 10830Å triplet within this channel,which significantly enhances the imaging observation capabilities of NVST.This paper provides a concise overview of the optical system associated with the near-infrared imaging channel,detailing data processing procedures and presenting several observed images.Leveraging a high-resolution image reconstruction algorithm,we were able to generate a narrowband image near the diffraction limit at 10830 Å with a temporal resolution of less than 10 s.
