The Research And Design A Microscope Photometer With CCD Detector

Microphotometer is a device to measure the intensity of light from micro surface. It canbe used to measure the reflectance of coal and other organic rocks, in order to determine thedegree of coal metamorphism, and the maturity of organic rocks. It is a basic laboratorydevice for coal geology and coalbed methane geology and petroleum geology and coalchemical industry field such as. There are some existing problems in the current laboratories:the devices are mainly imported; microscope and photometer can not be connected properlyin the imported device and the function is not enough. The thesis aims to research and designa Microscope Photometer with CCD array detector spectrograph as photoelectric conversionunit. The device is used to detect the maturity of the organic matter of coal and other minerals.By using fiber-optical as the transmitting medium, this new Microscope photometer integratesCCD detector photoelectric conversion device (input and output of signals), CCD imagesensor and measuring software on ORTHOPLAN-POL polar-and reflecting microscope. Theresearch and design of this new microscope photometer involve fully model selection,verification and processing about the parameter adaptability of the various parts of thehardware of the device; and the design and development of the software system connecting tothe hardware. Typical sample comparison testing was carried out between this new integrateddevice and Leitz MPV-3microscope photometer made in Germany. The results show that thisnew integrated microscope photometer meets all the technical requirements of the relatedstandards on stability, linearity, testing accuracy and effect of measuring software, etc.. Theresearch and design is the innovation breakthrough in the designing of the new MicroscopePhotometer with CCD array detector as photoelectric conversion unit. The new device istested to measure the wavelength of the visible light. Wavelength response is between200nm~1100nm; spectral resolution is between0.04-2nm. Supporting measure software for coal petrology is also developed. The device acquires the advantages of good performance,multifunction, measure efficiency, easy operation, small volume, and installation convenience.And it is being widely applied in laboratories of coal industry and universities.
