The TDM monochromator features low temporal dispersion and high optical throughput, both of which are key requirements of time-domain spectroscopy.
A versatile building block that can easily be incorporated into any optical system, its features include:
This unique range of features makes the TDM monochromator an ideal choice for applications requiring compact wavelength selection. Three models cover the spectral range from 200nm to 1600nm: TDM-800 (200-800nm), TDM-1200 (300-1200nm) and TDM-1600 (400-1600nm).
The TDM monochromator is a core component of our DeltaFlex range of fluorescence lifetime systems and is therefore readily available with a host of adapters and accessories such as our PPD detectors and diode light sources.
