T9/T10DCS Double Monochromator UV-Vis

T9DCS:      UV-Vis Spectrometer        

T10DCS:    UV-Vis Spectrometer        

The T9/T10DCS Spectrophotometer incorporates dual monochromator technology making it well suited to even the most demanding of applications in all areas of UV-Visible Spectroscopy.


The optical design of both the T9DCS and T10DCS offer extremely low stray light characteristics (≤0.00004%T NaI,220 nm) which allows for an extensive photometric range (-8.0 – 8.0Abs). Measurements at deep ultra-violet wavelengths can also be achieved with use of Nitrogen purged optics.


The instrument can be optically configured to suit the needs of the sample by means of a continually adjustable slit for precise control of spectral resolution and beam size adjustment by means of an attenuating wheel. 

Key Features

◆ True Double Beam Double monochromator Optics, and fully sealed to provide ultra-low stray light (0.00004%%T @220nm) and high photometric range (-8.0~8.0 Abs)


◆ 185– 900nm Wavelength range with Nitrogen purge


◆ Precise Wavelength accuracy is ensured by the integrated Mercury lamp for automatic correction
