Thin rigid endoscopes (borescopes)

 

Application:

  • Visual inspection of objects accessible only through holes of a small diameter
    (1 Е 6 mm);
  • Organization of hidden observation.

  • Defectoscopy of internal cavities in machine components;
  • Technical diagnostics of various units and assemblies without disassembling such as cylinders of car engines, gear reducers, collecting channels, lock mechanisms; diagnostics of turbine blades of compressors and aircraft engines;

  • Hidden observation over objects when performing special investigations;
  • Search of tabs and hiding places;
  • As small-sized objective lenses attached to stationary video observation systems.

Borescopes consist of an integrated fiber-optic bundle for illumination of a working zone band, a gradient optics system for image transmission, and an eyepiece section with diopter adjustment.

Endoscope layout

Thin rigid endoscopes (borescopes)

Borescopes are different in diameter and length of the thin working section.
Working diameters are in the range from 0.8 mm to 5 mm. The minimum working diameter is 0.6 mm (for the model without the integrated illuminating lightguide).
Length of the thin working section Ц from 30mm to 300 mm.

Viewing directions:

  • 0∞ - straight vision;
  • 30∞, 70∞, 90∞ - side vision.

The working area is illuminated with the aid of the illuminator whose light is transferred to the endoscope through the lightguide cable.

The small-sized OMA - 15 illuminator is fixed directly on the plug of the optical connector.

Extra-thin endoscopes (microendoscopes)

Extra-thin endoscopes (microendoscopes)
Replaceable working section with build-in illumination. An outer diameter is 1 mm

Microendoscopes are notable for very small diameters of the working section (up to 1 mm).

The minimum achievable diameter (without build-in illumination) is only 0.6 mm!

Due to very small sizes of formed images the microendoscope can not have the eyepiece section. As a rule, the images are seen in a TV format with the aid of a miniaturized video camera or video-glasses.
