MiniRaman microscope

World’s smallest confocal Raman microscope

The world’s smallest confocal MiniRaman microscope for 660 nm and 785 nm laser wavelengths is based on our miniRaman spectrometer, which performs Raman shift and Raman intensity calibration during every spectrum acquisition.

Due to the unique, patented technology* miniRaman microscope has very high throughput, perfect wavenumber accuracy and Raman intensity calibration via in-build reference channel.

MiniRaman microscopes provide diffraction limited spatial resolution, extremely high throughput and additionally equipped with transmitted visible light microscopy on separate camera sensor. MiniRaman microscope can be used in upright microscopy and inverted microscopy configurations. All what is need for switching between modes – flipping the device from top to bottom.

This instrumental setup allows for both sample viewing using the optical microscopy capabilities and performing measurements by Raman spectroscopy simultaneously.

The visual observation reveals morphological details of a sample (e.g. color, size, shape), whereas the spectroscopic measurement reveals information about the molecular structure and chemical composition of a sample.

MiniRaman microscope is suitable for samples that tend to fluoresce when exposed to laser radiation. Due to the usage of a 785nm laser, the excitation energy is low enough for these samples not to fluoresces or only to a minor degree.
