平凸的

Notice that this lens is actually different than the plano convex lens used in the original Galilean telescope, but still gives the same results.

请注意，这个镜头实际上是平凸比在原来的伽利略望远镜所使用的镜头不同，但仍给了相同的结果。

By extending the VBG external cavity length, and inserting a convex cylindrical lens between external cavity and LDA for transmiting. Phase-locked of external cavity is achieved by tilting of Bragg Grating external cavity. Experiment studied the stability of the in-phase mode far-field output at 35A. Wavelength is locked at 802 nm. The Full-Width Half-Maximum of locked specrum narrowed to 0.2 nm and the corresponding far-field divergence angle is 1.8 mrad.

通过拉长VBG外腔腔长，在VBG外腔和LDA中间插入平凸柱面透镜，采用偏转体布拉格光栅外腔进行外腔锁相研究，在注入电流35A时，获得稳定的同相单瓣模远场输出，波长锁定在802nm，中心主瓣峰值半宽压窄到0.2nm，对应的远场发散角为1.8mrad。

Matting were as granula convex peak exorbitance, fotographic and photoptic layer of PS gap is too large, resulting in a fine image so that the density of hihglights part of the net-point drop in the level of the gradient image is missing.

不净背颗粒较大，会变成颗粒凸峰过矮，胶片与PS版感平层的间隙过大，以致精粗影像难以还原，矮平局部网不背的稠度回升，图像阶调条理迷失。
