T8DS Double Beam UV-Vis

Arctic Light T8DS Double Beam UV/Vis Spectrophotometer


The Arctic Light 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 detector delivers exceptional sensitivity.  The true double-beam optical system coupled with an efficient and well proven electronic control system ensures high stability with low background noise.

Our package can include some or all of the following.
