The new UV-3600 plus UV-VIS-NIR spectrophotometer is equipped with three detectors—PMT (photomultiplier tube) for ultraviolet and visible regions, and InGaAs and cooled PbS detectors for the near-infrared region—to ensure high sensitivity across the entire measured wavelength range. Compared to spectrophotometers with only PMT and PbS detectors, the UV-3600 plus can reportedly reduce noise level to ensure high-accuracy measurements across the entire wavelength range.

The instrument’s high-performance double monochromator reportedly makes it possible to attain an ultra-low stray light level (0.00005% maximum at 340 nm) with high resolution. The wide wavelength range of 185 to 3,300 nm enables measurement across the ultraviolet, visible and near-infrared regions.
