介绍了双光束热透镜显微镜的共聚焦检测方案。该方案允许在0.35 microm3体积内测量低至1.2 x 10（-7）的吸收因子，通过使用100mw的加热激光功率入射到样品上。结果表明，当使用1.2的na为1.2的水浸物镜时，可以实现450 nm的轴向分辨率。
The use of a confocal detection scheme in a dual-beam thermal-lens microscope is presented. The scheme allows the measurement of absorption factors down to 1.2 x 10(-7) in a 0.35-microm3 volume by use of a heating laser power of 100 mW incident upon the sample. Results are presented that prove that a 450-nm axial resolution is possible when a 1.2 water immersion objective lens with a N.A. of 1.2 is used.
