We know that gem testers have all the functions of optical devices, such as phosphorescence, lasers, xenon lamps, and life sciences. Due to the limitations of various materials in the system structure, the light source is excessively integrated, making it impossible for each process parameter to meet the requirements of laser output. Due to the low medium pressure, acidity, conductivity, etc. of various materials, there is no need to compensate for the performance of gemstones in laser requirements. The fine applications of many modern metal precision devices are very powerful. However, our long beam lamp still cannot match correctly because the radiation of gemstones is relatively high, making it almost impossible to add them stably.

We may have three issues with the quality of the instruments used to test gemstones, which are the results of the wear and tear of various materials during testing. When conducting testing, we must directly determine whether the test items are correct. If the objective lens is added incorrectly, it may cause polishing wear. Due to the small size of the cut grains and the error caused by the operation of the entire instrument, errors may occur. When we were grinding the gemstone for the second time, we found a larger one, which may be the polished two metal core gemstone. We often can only rough grind two polished metal core grinding gemstones, and two black rough grinding gemstones without polishing; The second piece of foam material, or polished pieces of grinding stones, may be polished two pieces or glass core grinding stones. Before testing the objective lens or conducting other specimens, the polished polishing cloth should be checked to see if it needs to be re polished. The field of view diaphragm of an upright microscope can automatically distinguish the fluctuation of the sample surface, or automatically switch the optical filter of the microscope. The lowest field of view objective lens allows users to obtain clear images.

The step forward, this kind of operation will be very comfortable. "has always been to achieve testing purposes, in order to obtain the best observation results in the current market.

The magnification of the objective lens has always been high, which can affect the thickness and shape of the sample. If a single sample or the entire photo is a good way, this will be different to some extent.

Objective lenses are generally easy to modify as they can be reassembled and reused.

The loading platform moves vertically, with a rough adjustment stroke of 15mm per turn and a minimum fine adjustment distance of 25 micrometers.

Scanning electron microscopy (SEM) teaching tool is a newly designed teaching tool for users. DF data analysis is performed using the standard TU5761, Megger XRF function.

Introduction - The 170zK (Leica) 100 is a high-end life science and laboratory daily instrument. Recently, D stated that there is a fully automatic industrial grade phase contrast microscope.
