20100196207 | STRUCTURES FOR CONTROLLING LIGHT INTERACTION WITH MICROFLUIDIC DEVICES - Systems and methods for improved measurement of absorbance/transmission through fluidic systems are described. Specifically, in one set of embodiments, optical elements are fabricated on one side of a transparent fluidic device opposite a series of fluidic channels. The optical elements may guide incident light passing through the device such that most of the light is dispersed away from specific areas of the device, such as intervening portions between the fluidic channels.

The draft angle of the triangular grooves may be chosen such that incident light normal to the surface of the device is redirected at an angle dependent upon the indices of refraction of the external medium (e.g., air) and the device material. Advantageously, certain optical elements described herein may be fabricated along with the fluidic channels of the device in one step, thereby reducing the costs of fabrication.

20130294974 | AUTOMATIC ANALYZER - A light source radiates light onto a reaction vessel in which a sample is caused to react with a reagent.
