Double Beam UV-VIS Spectrophotometer
The T 90+ and T 92+ are a high performance double beam scanning spectrophotometer with a variable spectral bandwidth 0.1, 0.2, 0.5, 1.0, 2.0, 5.0nm.
The Czerny-Turner Monochromator with a holographic grating keeps stray light to a minimum and offers excellent optical resolution.
