Flat field design + NA=0.67, the edge and center of the full field of view are equally clear, suitable for imaging with near-infrared detector chips and quantum dot arrays; a 10mm working distance supports fine focusing, making it suitable for near-infrared super-resolution observation of ultra-thin samples (≤5μm).

Applications:
Near-infrared detector pixel analysis, quantum dot luminescence pattern detection, quantitative analysis of single-cell fluorescence signals.
