It was based on the principle of laser confocal microscope . and the two - dimensional scanning configuration was adopted by the optical scanner and the telecentric linear imaging objective lens of large numerical aperture to realize x - direction ' s scanning , and the conventional mechanical method using linear driver and linear guide track to y - direction ' s . the experiment results indicate that the device can run smoothly and rapidly , be operated easily and detect fluorescence effectively 儀器基于激光共焦顯微鏡的理論,采用振鏡和遠(yuǎn)心線性成像物鏡實(shí)現(xiàn)x向掃描;精密導(dǎo)軌和步進(jìn)電機(jī)實(shí)現(xiàn)y向掃描的檢測儀,經(jīng)驗(yàn)證,掃描儀具有快速、操作簡單、檢測芯片能力良好等特征,有望彌補(bǔ)市場的空缺。
