The Spectrum 3/ Spotlight 400 is a Fourier transform infrared (FTIR) spectrometer fitted with a microscope, attenuated total reflectance (ATR) and transmission accessories with the flexibility to measure across mid and far infrared ranges.
Quest Single Reflection ATR
This accessory facilitates rapid analysis of solids, powders, liquids and pastes in the spectral range of 7800 to 100cm-1 (1.3 µm to 100 µm).
Transmission
Analyse thin films (less than 100 microns), powdered samples and liquids in the spectral range of 7800 to 100cm-1(1.3 µm to 100 µm).
Spotlight 400 FTIR Microscope
The following are the capabilities of the microscope:
- Measurements of transmission or reflectance point spectroscopy or mapping and ATR imaging.
- Automated XYZ sample stage to enable chemical imaging using reflected or transmitted light with a maximum spatial resolution of 6.25 micron.
- An ATR imaging crystal is available for fast imaging at 1.56 micron spatial resolution - ideal for biological samples, as interference from water is significantly reduced.
The instrument caters to a broad spectrum of samples, including:
Organic powders, liquids, and films
Biological sections
Minerals
Polymers
