Patent ID: 7342662

Claim:
A sample analyzer comprising: a sample container for carrying a sample; a first light source for emitting a first light beam of a first wavelength with which said sample is irradiated; a second light source for emitting a second light beam of a second wavelength with which said sample is irradiated; a package which houses said first light source and said second light source, the package refracting said first light beam from said first light source and said second light beam from said second light source so that said first light beam and said second light beam extend in substantially a same direction and intersect each other in said sample; a detector for detecting a first beam of light which is said first light beam of said first wavelength that has passed through said sample, and a second beam of light which is said second light beam of said second wavelength that has passed though said sample; wherein said first light beam of said first wavelength intersects with said second light beam of said second wavelength at a substantially ½ position in said sample of the length of said beams in the direction of transmission thereof.
