Can the MFR-7 and UVMFR be combined into a single instrument that covers the UV-B through the visible/NIR?
No, (this is why we have separate products). An MFR-7 measures optical signals at a different order of magnitude than does the UVMFR. Hence the internal design of these two instruments is vastly different. Measuring UV requires a much higher gain level to measure the much smaller signals present. A SPUV, however, can be setup to cover from 300 nm all the way to 1040 nm.
