Abstract:
1. A microchemical system comprising: an exciting light source that outputs exciting light; a detecting light source that outputs detecting light; a light-guiding optical system that combines and guides the exciting light and the detecting light; an irradiating lens for irradiating the exciting light and the detecting light guided by said light-guiding optical system onto a sample; detecting means for detecting the detecting light that has passed through a thermal lens formed due to the sample being irradiated with the exciting light; analyzing means for analyzing the sample based on the detected detecting light; a first light-introducing optical fiber that introduces the exciting light outputted from said exciting light source into said light-guiding optical system; a second light-introducing optical fiber that introduces the detecting light outputted from said detecting light source into said light-guiding optical system; a two-wavelength multiplexing device which is provided in said light-guiding optical system, and which multiplexes the exciting light and the detecting light that have been introduced by said first light-introducing optical fiber and said second light-introducing optical fiber; and a light-guiding optical fiber that guides the multiplexed exciting light and detecting light to said irradiating lens; wherein said irradiating lens has chromatic aberration.
