Embodiment Construction
[0011] see figure 1 , the digital low-light sight optical system of the present invention, successively constitutes the main optical path by objective lens system, image intensifier 5, light combining prism 6, image transfer system, beam splitting prism 7 and eyepiece system. The objective lens system adopts a front group lens consisting of the first single positive lens 1 and the first doublet lens 2, and a five-piece structure formed with the single positive lens 3 and the single negative lens 4. The objective lens system of this structure can both It meets the achromatic and high-resolution image quality requirements of wide beam, and has the advantages of small size and light weight. The image relay system adopts a seven-chip double Gaussian structure, which can effectively eliminate the system's advanced aberrations and vertical axis aberrations, and ensure the system's excellent image quality; adopt the design idea of a shared image relay system, and the CCD relay syst...
