Optical apparatus and methods for chemical analysis
In one aspect, the invention relates to an optical apparatus for producing light of a predetermined intensity from light sources of less than the predetermined intensity. In one embodiment the apparatus includes a first light source; a second light source; a double dove anti-Gaussian generator in optical communication with the first light source; and a compensator in optical communication with the second light source. Light from the first light source passes through the double dove anti-Gaussian generator and light from the second light source passes through the compensator, and are combined to produce a flattened Gaussian intensity distribution. In another aspect, the invention relates to a method and apparatus for separating an image into subunits and reading the separate subimages out of the detectors in parallel.

10 . A fluidic reagent dispensing system comprising:
a plurality of reagent reservoirs;
a syringe pump having a plurality of controllable ports, each of said reagent reservoirs in communication with a respective one of the plurality controllable ports, one of said plurality of controllable ports being an output port;
a bubble detector in communication with said output port; and
a controller in communication with said syringe pump, said controller controlling the controllable ports, volume of aspiration and aspiration rate of said syringe pump.
11 . The fluidic reagent dispensing system of claim 10 wherein said syringe pump comprises a chamber and said controller is set to draw reagent from at least one of said a plurality of reagent reservoirs into said chamber in one of a transitional and turbulent manner.
12 . The fluidic reagent dispensing system of claim 11 wherein the Reynolds number for flow of the reagent during aspiration is greater than 2300.
13 . The fluidic reagent dispensing system of claim 10 further comprising a mixing chamber in communication with said bubble detector.
14 . A method of dispensing fluid reagents in a fluid reagent system comprising the steps of:
drawing a first volume of a first reagent from a first reagent reservoir into a chamber of a syringe pump; and
drawing a second volume of a second reagent from a second reagent reservoir into said chamber of said syringe pump, said second volume being larger than said first volume,
wherein the rate at which the second volume is drawn into said chamber is sufficient to cause one of transitional and turbulent flow of said second reagent.
15 . The method of claim 14 wherein the Reynolds number for flow of the second reagent is greater than 2300.
