Industrial Endoscopes

GAOTek endoscope provides a video feed record for detecting narrow and bending areas that other types of equipment cannot reach. Endoscope is an inspection tool for internal inspection of machinery without having to disassemble the machine, thus saving time and money. GAO Tek industrial endoscopes are reliable, high quality, and affordable instruments that provide an accurate live video feed for easier inspection of inaccessible or narrow areas. They are compact and portable allowing the user to work in complex conditions. They support standard 8G and maximum 32G, and come with a high-quality Li battery that lasts more than eight hours of use. They allow a direct connection to computers via USB interface for uploading and downloading data.


It was demonstrated in the 1840s that light could be guided along curving jets of water for fountain displays. In 1854, British physicist John Tyndall popularized the use of light to follow a jet of water flowing from a tank. In 1954, Professor Harold Hopkins and Dr. Narinder Kapany of Imperial College, London discovered that thin glass fibers were able to carry light due to their physical property of internal reflection. Light needs to travel in a medium of high refractive index, higher than the surrounding medium. Light inside the fiber is reflected off the inner surface at a shallow angle. Optical fibers were a major break-through in fiber-optic technology, and led to the development of the first gastroscope.

Starting in the early 1990s, fiber-optic imaging was rendered redundant by video chip endoscope with charge coupled device (CCD) sensors. The image quality of CCD-based instruments has undergone a progressive refinement that parallels the development in the field of photography as demonstrated by the advent of digital cameras. The early limitations of color imaging with CCD chips required synthesis of primary colors produced by a rotating wheel. The new CCD technology allowed the creation of CMOS (complementary metal oxide semiconductor) to reduce the cost and increase the quality of video imaging. The design of endoscopy has become an evolution for its diagnostic yield.

Numerous recent technological advances allow endoscopists more flexibility. These improvements include:

  • Loop-resisting Mechanism – Variable stiffness endoscopes and shape-locking over tubes made it possible to overcome the challenge of formation of undesired loops in the shaft of a flexible scope.
  • New Scope Technology – Novel scope designs simplify colonoscopic examinations and enhance visualization.
  • Imaging Advances – Recent advances in endoscopic imaging techniques allow early detection.
  • Magnification Endoscopy – A cap with a magnifying lens is fitted to the tip of an endoscope. When an object comes in contact with the lens, it is magnified without impairing the maneuverability of the scope.
  • DIC technology – Allows the user to measure the mechanical properties of different materials.
  • Infrared Technology – The instruments are now based on passive thermography, i.e. on temperature difference. There are two kinds of thermography - active and passive. Active is defined as applying a stimulus to a target to cause the target to heat or cool while passive is defined as measuring the temperature differences between target and the surrounding ambient conditions. Passive thermography allows monitoring of internal defects and makes for simpler quality testing.
  • Thermography technology with modulated ultrasonic excitation.
  • With further technological advancements, endoscope technology will likely introduce multifunctional endoscopes that house several combinations of imaging technologies to provide more flexibility in several applications.


GAOTek industrial endoscopes are reliable, accurate, and easy to use.

  • Compact and portable: Our endoscopes are suitable for working in complex conditions.
  • Standard 8G: They support standard 8G while being able to support a maximum of 32G.
  • Battery: High-quality Li-battery that lasts more than eight hours of use.
