Bring the microscope to your spectrometer!
Using a standard microscope for photoluminescence characterisation often means inefficient fibre-optic coupling to a microspectrometer, and difficult access for many sample configurations, such as side-emitting devices, or upright cryostats. Nor do standard microscopes offer flexibility for coupling multiple lasers for photoluminescence excitation.
HORIBA Scientific’s MicOS merges microscopy and spectroscopy, to provide optimal coupling from the sample all the way to the detector. Available in down- or side-looking configurations for side-emitting devices or upright cryostats gives you flexible sample access. An optional, fully automated stage for mapping and sample-positioning is available. The MicOS offers a flexible platform for the use of multiple lasers for sample excitation. The system includes a vision camera so you always see what you are measuring.
The MicOS can be used with any combination of laser wavelengths, both single wavelength excitation and multiple wavelength excitations. The laser sources may either be fibre coupled to the MicOS input or assembled in a laser train to free space couple the light into the MicOS. Fibre coupling provides ultimate flexibility, and free space coupling provides the best possible spatial resolution with high magnification objectives.
MicOS Microscope Head
The MicOS microscope head includes all of the coupling optics for directing the laser to the sample and collecting the signal and coupling it to the spectrometer and detector. It also includes a white light source for illumination of the sample and a vision camera for viewing the sample. The optical schematic below shows the layout of the MicOS head.
