Compact microscope Confotec® Uno
The new Confotec® Uno confocal Raman microscope from SOL instruments is a compact device with one built-in laser, either of 532 nm or 785 nm wavelength (optional), with a telescope and a single-channel imaging spectrometer on 120-mm vertical optical platform and a 4096-pixel linear CCD detector that allows to obtain high resolution spectra and high-efficiency light collection.
Benefits of the Confotec® Uno microscope
- High sensitivity – third-order silicon peak detection;
- High spectral resolution;
- Long-term stability in operation without additional adjustment of the device;
- Due to a one-piece monobloc design, Confotec® Uno does not require an optical table and can also be easily transported without the need for further adjustment;
- Guaranteed reliability: no moving parts in the device, spectrum automatic calibration provides long-term stability of the device and reproducibility of measurement results;
- Easy to use: just put a sample and select an area of interest; a smooth adjustment of a laser power is provided for a user convenience.
Features of the microscope
- A new type of low-noise detector, which is characterized by a high signal-to-noise ratio allows measurements without low-temperature cooling;
- Optionally, the microscope can be equipped with an automated table for obtaining 2D Raman images of various microscopic objects with a spatial XY resolution of about 1 µm, as well as with a protective cover to ensure Class-1 laser safety.
