		Rigid or flexible borescopes may be fitted with a magnifying device and a way to illuminate the work being inspected, usually illumination fibers contained in the insertion tube of the borescope.
		The eyepiece may be fitted with a coupler lens to allow the borescope to be used with imaging devices such as a video or CCD camera.
		A flexible borescope can be used to access cavities which are around a bend, such as a combustion chamber or "Burner Cans" in order to view the condition of the compressed air inlets, turbine blades and seals without disassembling the engine.

		The field-of-view of the Hawkeye borescopes is approximately 35°.
		Borescopes, however, have a very large depth of field — often from infinity down to an inch or less — that makes them easy to use without constant refocusing.
		Today, most borescopes use fiber optic illumination, using glass fibers to carry light from an external light source through a flexible light guide, then through the borescope, to the distal end.

	Endoscopic Shearography and Thermography methods for non destructive evaluation of lined pressure vessels
		The illumination beam should expand from the borescope to illuminate the test article within the appropriate imaging field of view with sufficiently bright and uniform intensity that the entire field of view may be recorded by the shearography camera.
		The use of a commercially available borescope with an existing shearography camera that was designed to use a telephoto lens imposes the constraint that the borescope must be adapted to optically and mechanically "fit" the shearography camera.
		The borescope must be supported such that performance requirements for minimization of bending and vibration are met and motion of the borescope relative to the interferometer is eliminated.

		The Hawkeye borescope consists of three units: the borescope with attached eyepiece; a right angle mirror tube that slips over the borescope and rotates 360 degrees; and a Mini-Maglite light source that screws into a fitting at the eyepiece and serves as the handle.
		The borescope can also be used without the rotating mirror tube, providing forward image viewing and is useful for examining the internal flashhole of a case, for example.

		Borescopes usually have a light source and a series of rods that allow magnified, illuminated viewing inside very small holes and apertures.
		Some borescopes use spaced achromats and others use the Hopkins design so the objective lens forms the image from one end of the borescope to the other.
		These features make the borescope a useful tool for crime investigation, but the use of so many tiny, expensive lenses and a lack of precision have limited its use.

	Colloidal Borescope tracks groundwater
		When the Colloidal Borescope is inserted into a monitoring well, it directly measures the movement of naturally occurring particles in groundwater, or colloids, as they flow through a well’s screened interval, which corresponds to a distinct lithographic unit in the subsurface.
		This evidence suggests that the faults are acting as preferential flow zones, which dominate the groundwater flow component and redirect the hydrocarbon contamination from the northwesterly regional flow direction to a southern direction parallel to the fault trend.
		ORNL is using the Colloidal Borescope to evaluate the effectiveness of natural flushing in cleaning the contaminated aquifer underlying DOE’s Grand Junction Project Office.

	September 2003 - Back to Basics
		Beginning with "eyeball" tests using optical borescopes or flexible articulating fiberoptic fiber borescopes (endoscopes) to view internal discontinuities of machinery, video borescoping began when inspectors first mounted boxy analog video tube cameras to the borescope eyepiece and observed tests on a television.
		Video borescope type CCD sensors are supplied by only a few manufacturers, therefore, multiple scope models and brands may use the same CCD.
		Each video borescope user should work towards the establishment of remote visual testing standards within his or her organization beginning with good trend monitoring documentation.
