Disclosed is a high-temperature endoscope of an ingot growth apparatus in which impurity deposition is prevented by having a structure that increases a flow rate of an inert gas for preventing impurities from being deposited. A high-temperature endoscope preventing impurities of an ingot growth apparatus from being deposited, according to one embodiment of the present invention, may comprise: a frame extending to the inside of a chamber of the ingot growth apparatus and having a gas discharge port provided at an end portion thereof through which an inert gas is discharged; a lens installed at the center of the end portion of the frame and protected by the inert gas discharged from the gas discharge port; and a guide tube installed on an outer surface of the frame and having a guide portion extending from the end portion of the frame so as to guide the inert gas to prevent impurities from being deposited on the lens by increasing a flow rate of the inert gas.

Systems, methods, and devices are provided that facilitate reducing wear of threads of a camera head of an imaging system (e.g., a borescope), thereby increasing the lifespan of an imaging system. In some embodiments, an imaging system is provided that includes a camera head made of anodized TiAl.sub.6V.sub.4 and coated with a solid film lubricant. The imaging system can also include a probe tip made of 303 stainless steel and coated with a diamond-line carbon coating. By using a camera head made of anodized TiAl.sub.6V.sub.4 and coated with a SFL in combination with a probe tip made of 303 SS and coated with a DLC, wear on threads of the camera head can be reduced, thereby increasing the lifespan of the imaging system.
