DB 620 UV/Vis[NIR] Spectrophotometer, Olis, Inc. (CAT#: STEM-LE-0753-LC)

DB 620 UV/Vis[NIR] Spectrophotometer is our small scanning dual-beam absorbance spectrophotometer, optimized for microsecond dynamics, and is stable and noise-free, so it is ideal for long-term thermal fusion and equilibrium research. This modern digital optical platform provides high-precision, high-performance true dual-beam data at a rate of 500 ns with or without related scans. When the acquisition time is one millisecond, and 1000 data points are assembled on a straight line to return 250 nm RMS noise of 0.0014 AU; when the acquisition time is 1 second, the RMS noise is reduced to 0.00016 AU. Scanning between these high-speed fixed-wavelength readings will produce an extremely low noise spectra.
