Stray light ≤ 0.01%T T90+ UV-Vis Spectrophotometer for Life Science & Biochemical
T90+ is a high performance double beam scanning spectrophotometer with a variable spectral bandwidth. The Czerny-Turner Monochromator with a holographic grating keeps stray light to 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.
