Description

Technical Field

[0001] This utility model relates to the field of diamond preparation technology, and more specifically, to an infrared temperature measuring device for preparing diamond by MPCVD method. Background Technology

[0002] When using MPCVD to grow diamond single crystals, an infrared thermometer is needed to measure the temperature of each seed crystal surface within the chamber. This allows for a more direct understanding of the seed crystal growth status, enabling adjustments to the gas pressure and power of the MPCVD equipment to control the temperature within the optimal range for seed crystal growth. Since there are a large number of seed crystals within the chamber, and to control the quality of seed crystal growth, frequent surface temperature measurements are required during the growth process. This necessitates frequent rotation of the micrometer used to control the positional accuracy of the infrared thermometer. Consequently, wear, chipping, and damage occur on the micrometer's screw and anvil, preventing proper contact between the screw and anvil and hindering the accurate temperature measurement. This can even prevent temperature measurements of the seed crystal surface near the edge of the molybdenum wafer within the chamber, thus affecting the seed crystal growth quality. Therefore, modifying the infrared temperature measurement device is crucial. Utility Model Content
