Borescopes -Fundamental Aspects of Design

Borescopes are the digitally controlled optical devices used for remote inspection of narrow and long structures. For example you can consider water pipelines, gas pipes, drain lines, industrial chimneys and sewer lines etc. The core structure of Borescopes consists of camera head, magnetic mount, flexible tube, power cables, precision lenses, prism, cylindrical body, eyepiece and a digital display unit. They can travel over long distances within the pipes and scan the structures for micro and macro level damages. They send the data to the receiving unit at the monitoring place. You can convert the images and other data into useful information for repairs and maintenance activities. You may also export the data into software applications for helping decision support systems.

Borescopes Borescopes Technical Specifications

  • Outer Body: – The construction of the Borescopes outer rigid body plays a critical role in determining its endurance and durability. The mainly required features are resistance to pressure, accidental damages, short circuits, water leakage and other forms of stress. Most of the Borescopes are made from steel, aluminum, fiberglass, brass or the combination of metallic alloys. They are highly rustproof in nature. The designers take special care to embed shockproof characteristics to the outer body.
  • External Crawler: – The standard Borescopes come with external crawlers to get a firm grip on the walls of pipes. They are designed with minimum friction and maximum flow speed while operating. They are capable of climbing up and down vertical pipes without losing grip on the walls. The design of Borescopes crawlers are highly flexible to fit into pipes of variable diameters. A typical crawler is made of brass body, powerful motor, drive and wheel. The attached inclinometer can send clear data through any type of gradients across long distances.
  • Camera Head: – The camera head of Borescopes consists of a powerful image and video capturing device. This can work under various intensities of light and even in darkness. This is placed within a flexible tube which rotates through 360-degrees in horizontal direction and 180-degrees in vertical direction. The head is supported by power-packed LED lights which can penetrate through the densest liquids with maximum turbidity. The camera can capture the faintest of light rays passing in its focus area.
  • Flexible Prism: – Many types of the high quality Borescopes are mounted with flexible prism for magnifying the captures image. For example the rigid models of Borescopes consist of fiber optic enabled illumination with 360-degree view. The prism is made of 5 internal walls (Penta-structure) which orients the image and sharpens it to the most accurate levels. By using such Borescopes it is possible to extend the best view till the edge of the field. They can detect the micro level defects in the pipes and other structures being inspected.


  • Digital Display: – The digital display units of the Borescopes can show enlarged images to micro level accuracy. They are made of large LCD monitor (sealed in aluminum case), daylight and night vision unit (with backlight), control panel (You may opt for touch-screen or manual), USB-port (for saving and exporting data) and other accessories as required.
