Compact dual-channel microscope Confotec® Duo
The new Confotec® Duo microscope from SOL instruments is a compact device with two integrated lasers (532 nm and 785 nm with an optical isolator) with the telescopes and a dual-channel imaging spectrometer. Confotec® Duo, based on Raman scattering technique, has been designed to provide a new level of convenience in the class of compact Raman microscopes offering easy, rapid measurements of sophisticated samples with improved spatial resolution.
Confocal microscope Confotec® Duo
For more than 25 years SOL instruments has been in progress discovering unique solutions for the ever-growing researchers’ needs and challenges in various fields of application.
Our extensive knowledge of cutting edge technology in the field of Raman spectroscopy has allowed us to create the instrument that meets the needs of Raman researchers with clear understanding of how it can be applied to solving a wide range of different tasks in science, industry and health.
The new Confotec® Duo, based on Raman scattering technique, has been designed to provide a new level of convenience in the class of compact Raman microscopes offering easy, rapid measurements of sophisticated samples with improved spatial resolution, allowing the users to do more with less.
Configuration
The confocal Raman microscope Confotec® Duo is a compact instrument which uses two integrated lasers (532 nm and 785 nm with an optical isolator) with the telescopes and a dual-channel imaging spectrometer.
A sample under investigation is lighted by the light emitting diode source. The integrated video camera allows to observe a sample and direct laser radiation to the area of interest much more accurately.
An automated stage is used to select the research area of interest and for 2D mapping. For a two-laser input of radiation, a patented method based on modern developments in optics has been applied instead of the traditional mirror (beam combiner), which combines laser beams and causes energy loss.
Assured reliability
When operating Confotec® Duo, a user is not distracted by preparation of the instrument for research as well as its maintenance. The absence of movable elements in the instrument and the automatic spectral calibration ensures long-term stability of the instrument and reproducibility of measurement results.
Operation of the instrument is limited by installation of a sample for analysis and selection of the area of interest. In the process of operation a user is assisted by a smooth adjustment of the laser power.
