概要（Overview）

The V-660 is a double-beam spectrophotometer utilizing a double monochromator and a photomuliplier tube detector. The use of a double monochromator provides higher resolution with extremely low stray light (0.00008%) to assure more precise measurement over a wide photometric range. Extended photometric linearity up to 6 Abs enables measurement of highly absorbing samples and is also effective for filter measurements approaching 0 %T.
