The Olis DB 620 UV/Vis [NIR] Spectrophotometer is our small scanning dual beam absorbance spectrophotometer, optimized for microsecond kinetics and so stable and noise-free that it is ideal for lengthy thermal melts and equilibrium studies, too.

This modern digital optical bench provides high accuracy, high performance true dual beam data at rates to 500 ns with and without associated scanning. With one millisecond of collection time, 1000 data points are fitted to a straight line to return RMS noise at 250 nm of 0.0014 AU; with 1 second collection time, RMS noise lowers to 0.00016 AU. Scanning between these high speed fixed wavelength readings results in extremely low noise spectra.

Hardware includes the new DeSa subtractive double grating monochromator for selecting and scanning the wavelengths. This tiny 7-sided monochromator uses two huge 40 x 45 mm gratings for outstanding light throughput, even down to the lowest wavelengths. These holographically blazed gratings can be for ultraviolet, UV/Vis, visible, Vis-NIR, or NIR. All associated light sources and detectors will be selected by Olis to be compatible with this blazed grating range. The spectral resolution is 0.5-5 nm, based on the slit width used; slits are interchangeable fixed slits of 0.5, 0.6, 1.24, and 2 mm wide, with other sizes available by special request.
