TDM - The Time-Domain Monochromator

The TDM monochromator features low temporal dispersion and high optical throughput, both of which are key requirements of time-domain spectroscopy.

Segment: Scientific
Division: Fluorescence
Base product
Manufacturing Company: HORIBA Scientific

A versatile building block that can easily be incorporated into any optical system, its features include:

  • Full automation of wavelength, exit and entrance slits, and shutter
  • Choice of control interface: USB, or F-link for plug-n-play integration with DeltaFlex components
  • Integral shutter saves space and components in your optical path
  • (shutter may be controlled in software and/or electronically from your own interlock circuit e.g. to protect sensitive detectors)
  • Rugged, compact construction
  • Low time dispersion and high throughput

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.

Measuring PL Upconversion Spectra and Lifetimes of Lanthanide-Doped Nanoparticles
Measuring PL Upconversion Spectra and Lifetimes of Lanthanide-Doped Nanoparticles
Upconverting lanthanide-based nanomaterials exhibit a unique fluorescence anti-Stokes shift, which enables them to convert NIR wavelength excitation into visible shorter wavelength emissions (NIR to UV-Vis).
Characterizing Lanthanides in Glasses for Optical Applications
Characterizing Lanthanides in Glasses for Optical Applications
Glasses are essential materials with a multitude of uses and many forms. In the area of optoelectronics there is an interest to modify the glass composition to favor the incorporation of lanthanide elements.

Upconversion of Lanthanide-containing glasses using DD‐980L excitation
The phenomenon of upconversion is an optical process that takes in lower energy (longer wavelength) photons and emits higher energy (shorter wavelength) photons.

Measurement of carrier lifetime in perovskite for solar cell applications
Hybrid perovskite photovoltaics (PV) show promise because of their good efficiencies, which can be around 20%. Along with their PV characteristics, perovskite materials exhibit a high degree of radiative recombination.
Time‐resolved luminescence of security inks from the UV to NIR
Time‐resolved luminescence of security inks from the UV to NIR
The use of security features, such as luminescent inks, has increased significantly in an attempt to prevent fraud and counterfeiting of materials and goods.
Time‐resolved Fluorescence for Monitoring Food Composition
Time‐resolved Fluorescence for Monitoring Food Composition
The use of time‐resolved fluorescence has expanded as the relative cost of instrumentation has decreased in recent years. One area where this is especially true is in the food industry, where time‐resolved fluorescence has been applied in the characterization of food stuffs as well as aspects related to food safety and degradation.
Monitoring Whole Leaf Fluorescence Using Time‐resolved Techniques
Monitoring Whole Leaf Fluorescence Using Time‐resolved Techniques
Light incident on a leaf can be absorbed by chlorophyll to commence the photosynthetic cycle. Excess energy can be liberated as heat or by emission of fluorescence and this can be used to assess the efficiency of the photosynthetic process. Because of the Kautsky effect, the amount of fluorescence emanating from photosystem II (PSII) is not constant. There is an initial rise, upon illumination followed by a decrease caused by PSII closing down, as it is unable to transfer electrons. There can also be a contribution from PSI to the overall fluorescence. Here we employ different time‐resolved fluorescence techniques to demonstrate the types of measurement that can be performed on a whole leaf.
The Measurement of Singlet Oxygen Lifetime Sensitized using Rose Bengal
The Measurement of Singlet Oxygen Lifetime Sensitized using Rose Bengal
The study of singlet oxygen (1O2) is of interest, principally, as it is a highly reactive species. It can be produced by photosensitisation, usually of a molecule such as a dye or porphyrin. Thus, by the appropriate selection of sensitiser, the presence of oxygen and light, 1O2 can be selectively generated. From a biological aspect it has the ability to damage and destroy cells, which has lead to interest in its use as an anticancer agent in photodynamic therapy (PDT).

Effect of temperature on HSA structure inferred using timeresolved room-temperature phosphorescence
To access intrinsic amino acids, such as tryptophan, as probes, the UV excitation wavelengths for pulsed phosphorescence measurements have long been the preserve of low-repetition-rate gas-filled lamps or larger laser systems. Recent developments have enabled the use of interchangeable semiconductor diodes, with their inherent ease of use. SpectraLEDs provide spectral coverage from the UV to the near-IR.

Plasmon enhancement of protein fluorescence by silver nanostructures
The use of metal surfaces in conjunction with fluorescence molecules employing a plasmon effect, sometimes referred to as metal enhanced fluorescence, can be advantageous because of the possible enhancement of photophysical properties. For example, the emission intensity of the fluorophore, can be improved.
