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.
