     高清晰度透镜,又称超像素透镜,与普通透镜相比,具有高清晰度、强的光谱透射能力、更精细的制作工艺等优点。通常以透镜成像圆基和0.7视场的图像分辨率作为判断镜头清晰度的标准。成像圈底座和0.7视场可达1000 TVline以上,称为高清晰度透镜。

     High definition lens, also known as super large pixel lens, compared with ordinary lens, has the advantages of high definition, strong spectral transmission ability, fine fabrication process and so on. The imaging resolution of ring base and 0.7 field lens is usually selected as the evaluation standard of imaging lens definition. The ring base and 0.7 field can reach more than 1000 TVLine, which is called high definition camera.
