Abstract: A spectrometer 1A is provided with an integrating sphere 20 for observing measured light emitted from a sample S of a measurement target, and a Dewar vessel 50 which retains a medium R for regulating temperature of the sample S, so as to cover the sample S and a second container portion 50b of which is located so as to face the interior of the integrating sphere 20. The sample S can be easily regulated at a desired temperature with the use of the Dewar vessel 50 retaining the medium R so as to cover the sample S. As the second container portion 50b is located so as to face the interior of the integrating sphere 20, the temperature of the sample S is regulated by the medium R, while inhibiting an external ambience around the integrating sphere from affecting the sample S. Therefore, the sample S can be efficiently regulated at a desired temperature.

Abstract: A biological aerosol detector is provided. The biological aerosol detector uses a semiconductor optical source with an ultraviolet emission band to excite biological molecules in an aerosol sample. Filtering optics are configured to attenuate radiation from a secondary emission band of the optical source to prevent false signals due to scattering of secondary emission band radiation from non-biological molecules. An intake/exhaust manifold that includes an intake pipe that fits within a concentric exhaust pipe is also provided. The intake/exhaust manifold planarizes the flow of the sampled aerosol to maximize the time of irradiation. An electrostatic sampling grid is also provided to selectively draw biological molecules having a net charge into the optical chamber.
