Abstract. Optical sensors based on UV-visible absorption, fluorescence, phosphorescence, chemiluminescence, surface plasmon resonance, and surface-enhanced Raman scattering techniques are widely used to detect trace levels of pesticides. Generally,Light Collection and Optical System Throughput,No optical system can focus a poor quality beam to a good image of the source. So, while a low F/# singlet lens (≤F/4) may be an efficient collector, you will get such a poor output beam that you cannot refocus it efficiently. Our Aspherabs™ address this problem, and we use doublet lenses to reduce aberration in our F/1 condensers.[MCQ's] Optical Communication - Last Moment Tuitions,52.
