Optical flow channel measuring instrument

An optical measuring instrument, comprising:

• a flow channel for allowing a specimen to be circulated therein, said flow channel including a top surface and a bottom surface;
• a first light source including a light emitting diode for emitting light upon said top surface of said flow channel to be used for optical adjustment and/or image confirmation in said flow channel;
• a second light source for irradiating light upon said top surface of said flow channel to irradiate light upon the specimen circulated in said flow channel;
• and
• a light detector for detecting the spectrum intensity of the light emitted from said first and second light sources;
• an image confirmation means for carrying out image conformation in said flow channel based on optical information generated through said flow channel by irradiating the light upon said flow channel using said first light source;
• and
• a light separation means for separating the light transmitted through said flow channel to light to said light detector and light to said image confirmation means.
