凹凸透镜

分析了该极限随LD光束的线度、透镜的折射率和凹凸透镜镜面曲率半径的函数关系，并作出了函数关系图。

We analyzed and plotted the limitation as a function of LD 's beam dimension , the index of lenses and the radii of the curvature of the meniscus .

用于中、小光学球面凹凸透镜的成盘或单件抛光加工。

For medium and small spherical convex lens into the optical disk or a single piece polishing .

分析了用凹凸红外透镜聚焦三维9只放电管轴对称折迭组合腔二氧化碳激光器的输出光束。

The corresponding numerical calculation has been done . 2 , By using of concave-convex infrared lens , the output laser beams from three dimensions ASFC CO2 laser having nine discharge tubes have been focused , which have been studied .

根据旁轴矩阵、以及分步搜索法寻找到满足输出光束具有较小的出射角、较长焦深的凹凸红外透镜的光学表面参数。

The parameters of optical surface of concave-convex infrared lens which can focus laser beams to achieve the output laser beams with lesser output angle and longer focus field . It has been calculated according to paraxial approximation , matrix theory and step by step searching methods .
