Abstract:
1. A system for optical analysis of targets comprising: an illumination source producing an illumination beam; a stage for holding a sample onto which said illumination beam is directed; a first objective lens collecting light from said sample and transmitting said light as a collected light beam; a first imaging lens that receives collected light from said objective lens and focuses said collected light; a first area array detector positioned to detect collected light focused by said first imaging lens; a second objective lens collecting light from said sample and transmitting said light as a collected light beam; a second imaging lens that receives collected light from said objective lens and focuses said collected light; a second area array detector positioned to detect collected light focused by said first imaging lens; a processor that simultaneously integrates signals from said first and said second detector, wherein said processor integrates a signal from a first detector for a first time interval and said processor integrates a signal from said processor for a second time interval, wherein said first time interval is shorter than said second time interval.
