產品介紹

Confotec MR150

It is a multifunction and compact confocal microscope. MR150 is the best Raman microscope in its class that deserves the maximum score for the price/quality criterion due to its spectral resolution, spectral calibration accuracy, universality, and ability to perform a variety of Raman measurements. Four configuration variants allow to choose the best system solution for your needs: MR150-SMR, MR150-SR, MR150-S and MR150.

產品說明

>  Fully integrated with a standard optical microscope
>  Rigid design, no preadjustment is needed
>  Compact spectrograph with a fixed position of Grating provides high thermal and temporal stability of  spectral measurements
>  Nondestructive analysis, no special requirements for sample preparations
>  Two automatic switchable lasers with different wavelengths allow to measure the Raman spectra of the various samples without influence of fluorescence background
>  Two independent imaging spectrometers allow to optimize the spectral range for each of the two installed lasers or achieve an extremely high spectral resolution using Echelle grating in a spectrometer
>  Only some sample areas are located in focus due to limited confocal depth of field. A high-speed reflected unit allows you to quickly find a sample focus areas and to use them for Raman measurements. This provides a significant gain in time and allows you to immediately apply a high numerical aperture objective to record high spatial resolution Raman maps
>  High speed and high spatial resolution panoramic Rayleigh scattering imaging using a galvano-mirror scanner and an automated microscope stage
>  Automatic spectral calibration
>  The whole spectral range at once may be recorded, without the need for scanning and spectrometer tuning

Configuration

The most complete configuration corresponds to the model MR150-SMR, consisting

 >  Microscope with an automated stage
 >  Two manually switched lasers: one laser is integrated into the Raman system (473 nm or 532 nm), another one is external (633 nm or 785 nm)
 >  Two independent imaging spectrometers in one housing, each of which has a diffraction grating in the fixed position and a CCD detector cooled by the Peltier element
 >  X-Y galvanometer scanner
 >  Z- piezoscanner
 >  Reflected Unit for high speed imaging using Rayleigh scattering from a sample (3 sec / frame, 1001 x 1001 points)
