T8DS is a high performance double beam scanning spectrophotometer with a variable spectral bandwidth. 

The Czerny-Turner Monochromator with a holographic grating keeps stray light at a minimum and offers excellent optical resolution.

The use of a photomultiplier tube as detector delivers exceptional sensitivity.

The true double-beam optical system coupled with an efficient and well proven electronic control system ensures high stability and low background noise.

Key Features

  • Czerny-Turner Monochromator with high resolution holographic grating
  • High performance variable (0.1, 0.2, 0.5, 1.0, 2.0, 5.0nm) spectral bandwidth
  • High resolution, excellent performance, long term stability
  • Additional accessories for multi-application, support the ultra-volume cuvettes
