Cintra 4040

Description

The Cintra 4040 is a true double beam, double monochromator spectrometer

which offers the ultimate in resolution and sensitivity. Using a variable slit width from 0.1 to 2.0 nm in 0.1 nm steps, and dual Littrow monochromators in a Czerny Turner arrangement to achieve the highest resolution with extremely low stray light and photometric linearity of better than 1.2% at 5 Abs. The wide dynamic range and excellent other optical specifications make the Cintra 4040 the best performing UV instrument in its price range allowing for the most demanding applications.
