| 摘要 |
A detector for optically detecting biological aerosols in a sample volume using non-imaging optical components (NIOCs) includes a light source configured to stimulate bio-fluorescence of tryptophan or nicotinamide adenine dinucleotide. In at least one embodiment, a sample volume and each non-imaging optical component are defined by surface features in each of a first monolithic structure and a second monolithic structure, when the first monolithic structure and the second monolithic structure are disposed in a facing relationship. In at least one embodiment, each NIOC comprises a compound parabolic collector. To facilitate volume production, the monolithic structures can be molded. Preferably, the sample is a volume of a gaseous fluid, such as air. |
