PHOTOMETRIC PART FOR CHEMICAL ANALYSIS

摘要

PURPOSE:To provide a function as an incubator as well to a titled part by fitting a light source into a block which is made of a material having high heat conductivity into a shape to permit imposing a chemical analysis slide and providing a control means to flicker the light source according to the output of a temp. sensor which detects the temp. of the block. CONSTITUTION:The light source 3 emits the irradiation light suitable for measurement of a slide 5. The irradiation light passes an irradiation light passage 2C in the block 2 and is made incident perpendicularly on the measuring surface 5a of the slide 5. The reflected light thereof passes a reflected light passage 2D and advances toward respective optical sensors 4. The light source 3 is lighted up in the case of using this photometric part as the incubator. The heat emitted from the light source 3 is transmitted to the slide 5 by the block 2 consisting of aluminum and having the high heat conductivity when the light source 3 is lighted. The temp. sensor 10 is provided in the block 2 and the temp. of the block 2 is controlled to the prescribed temp. suitable for maintaining the slide 5 at the prescribed temp.
