报道了由硅光电池组成的适于在显微镜等微焦系统上进行光功率测量的光电型功率计, 具有光谱响应范围广、线性好、灵敏度高、稳定性好、速度快、使用方便等特点。其微型光探头适于放置在不同显微载物台的样品玻片及样品池上, 包括置于溶液中模拟样品所处的环境与位置, 对投射到显微镜玻片样品上的实际光功率进行测定,并具有换档功能,可准确测定不同波长不同水平(0.1～50 mW)的光功率。

We report a micro-laser power meter, which is made of silicon photoelectric cell for measuring the laser power from micro-focus systems. The power meter has the characteristics of wide spectrum response, excellent linearity, high sensitivity, good stability, fast speed, and convenience for using. The micro-laser power meter, can be placed on the platforms in different kinds of microscope, even in the solutions of culturing biological samples, to measure the laser power projecting on samples for simulating the real environment and position of the samples. It is also suitable for the measurement of different wavelengths and different power levels (from 1～50 mW) of light.
