Claim Text:
1. A fluid treatment system comprising: a flow cell for containing a flowing fluid in an interior thereof, the flow cell having (i) a fluid entry, (ii) a fluid exit, (iii) a treatment region disposed between and fluidically coupled to the fluid entry and exit, and (iv) an interior surface diffusively reflective to ultraviolet (UV) light; a first end cap disposed at a first end of the flow cell and gaplessly joined to the flow cell, the first end cap having a sidewall diffusively reflective to UV light; a second end cap disposed at a second end of the flow cell opposite the first end of the flow cell and gaplessly joined to the flow cell, the second end cap having a sidewall diffusively reflective to UV light; a first window disposed between the flow cell and the first end cap, the first window (i) substantially preventing fluid flow into the first end cap and (ii) being substantially transparent to UV light; a second window disposed between the flow cell and the second end cap, the second window (i) substantially preventing fluid flow into the second end cap and (ii) being substantially transparent to UV light; one or more first UV light sources disposed outside of the first end cap and positioned to emit UV light into the first end cap, the sidewall of the first end cap being configured to diffusively reflect at least a portion of the UV light into the treatment region; one or more second UV light sources disposed outside of the second end cap and positioned to emit UV light into the second end cap, the sidewall of the second end cap being configured to diffusively reflect at least a portion of the UV light into the treatment region; a third window disposed between each of the one or more first UV light sources and an interior of the first end cap, each third window being (i) associated with a first UV light source, (ii) disposed within the sidewall of the first end cap, and (iii) substantially transparent to UV light; and a fourth window disposed between each of the one or more second UV light sources and an interior of the second end cap, each fourth window being (i) associated with a second UV light source, (ii) disposed within the sidewall of the second end cap, and (iii) substantially transparent to UV light, wherein:
