Tecan’s Quad4 Monochromators technology uses two excitation monochromators and two emission monochromators to offer outstanding flexibility, eliminating the cost and drawbacks of wavelength filters for research applications.   

The premium Quad4 Monochromators system of the Infinite M1000 PRO plate reader further optimizes this technology, using a flash lamp with double the power and switchable flash frequency settings for fluorescence intensity to provide even more light to both the sample and the detector, as well as offering improved spectral blocking and extended stray light reduction down to 2x10-7.   

The Infinite M1000 PRO offers broad wavelength selection, from UV to NIR, with flexible bandwidth adjustment for optimization of fluorescence intensity based applications.   

Patented technology allows the bandwidth of both the excitation and emission monochromators to be independently set in 1 nm steps. Bandwidth adjustments are possible for all fluorescence-based measurements, including fluorescence scans (excitation, emission and 3D), fluorescence polarization emission, FRET, time-resolved fluorescence (TRF) and time-resolved FRET (TR-FRET). Optimizing monochromator bandwidth results in improved instrument sensitivity, particularly for multiplexed and FRET assays.
