Microscope measuring techniques:
Transmission brightfield, transmission darkfield, polarisation, epi-reflection, epi-darkfield, epi-polarisation, fluorescence.

Measuring principle:
Photomultiplier spot measurement. On manual selected areas of interest the reflection light is detected and compared with reflection standards. Depending on the instruments configuration the size of the measuring field can de defined by fixed or variable diaphragms. Backward illumination enables the user to optimise the instruments adjustment. The electronic control offers a high dynamic range and takes the parasitic light automatically into consideration as well as the dark current.

J&M TIDAS MICROSCOPE PHOTOMETER MSP 200

This is a general purpose high quality microscope-photometer for many applications including:

Applications in Geology and Petrography

Petrographic analysis have been recognised internationally as important in the context of the genesis, metamorphism and usage of coal. The measurements of single coal provide information regarding the rank, the maceral and microlithotype compositions and the distribution of minerals. Mainly the measurement of Vitrinite reflection in a coal blend is a useful tool to get the information about some important chemical and technological properties but also the comparison of the Liptinite Fusinite and Inertite shares has an important part in the classification of the different blend types.

The J&M photometer TIDAS MSP 200 operates to the DIN/ISO standard in the data acquisition procedure as well as in the analysis mode. Final histograms display the results in quantitative columns and relative shares.
