PURPOSE:To obtain a measuring apparatus of absorbance incapable of shortening an optical path of a sample even if a sample case is made small-sized by setting one surface of the sample case to a reflecting surface and lengthening the optical path in the sample to >= twice. CONSTITUTION:A measuring light 9 emitted from a light source 1 is condensed by a condenser lens 2, transmitted through a half mirror 3, made incident upon the sample 7 from an incidence surface of the case 6, transmitted through the sample 7 and attained to the reflecting surface 5 in which mirror, etc. is attached to the case 6. Measuring light reflected at the surface 5 is transmitted again through the sample 7 and attained to the incidence surface 4. Transmitted measuring light 10 left from the surface 4 of the case 6 is reflected by the mirror 3, and introduced into a spectrophotometer 8. |
