T9/T10DCS Double Monochromator UV-Vis

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.


  • 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.
  • Continuously selectable spectra bandwidth from 0.1–5nm.
  • Beam size continuously adjustable for variety of applications including ultra-volume cuvettes.
  • Large sample compartment suitable for all kinds of accessories, especially for 150mm integrating sphere.
  • Support WIFI communication in field operation
  • The integrated Mercury Emissions Lamp with automatic correction function ensures precise wavelength accuracy.
  • Scan Speed: 1000 nm/min, 1500 nm/min location speed.
  • Wavelength Range: 185-900 nm.
  • Wavelength Accuracy: ±0.2 nm.
