The invention discloses an optical camera lens which comprises a plurality of stacked optical lenses, an air spacing piece is arranged between every two adjacent optical lenses, and the optical lenses and the air spacing pieces are respectively provided with antireflection films. The invention discloses a manufacturing method of the optical camera lens and further discloses a micro projection system. According to the optical camera lens, the antireflection films are plated on the optical lenses and the air spacing pieces, so that the reflectivity of the optical camera lens is further reduced, the light transmission effect is improved, and the accuracy of the optical camera lens is improved. 本发明揭示了一种光学镜头，包括若干堆叠设置的光学镜片，相邻所述光学镜片之间设置有空气间隔片，所述光学镜片和所述空气间隔片上分别设置有减反射膜。本发明揭示了上述光学镜头的制造方法，本发明还揭示了一种微型投影系统。本发明的优点包括通过在光学镜片以及空气间隔片上都镀上减反射膜，进一步降低了光学镜头的反射率，提高了光透效果，提高了光学镜头的精确性。
