This review focuses on recent developments in additive manufacturing (AM) of precision optical devices, particularly devices consisting of components with critical features at the micro- and nanoscale. These include, but are not limited to, microlenses, d
A high-power, high-energy Ho:YAG oscillator resonantly pumped by a Tm-doped fiber laser is presented. A maximum continuous output power of 38 W with a slope efficiency of 51.9% is achieved at the wavelength of 2.09 μm, and
光瞳像差的存在会导致实际光瞳和理想近轴光瞳的形状和位置出现差异,从而对光学系统的成像质量产生间接的影响。由于光瞳球差会影响光瞳的位置,而在某些使用机器视觉的测量系统中,入瞳位置作为摄像机的光心,形成了机器视觉中的一种重要参数,当入瞳位置发生变化时,将会影响到测量的准确性,尤其在高精度的测量领域。介绍了光瞳像差的基础理论,以SCOTS(Software Configurable Optical Te
