Introduction to Different Types of Borescopes

By on April 1, 2018

In this session you can get to know the brief overview on different types of Borescopes, their design, functionality and application areas. All of them have flexible outer body with 360-degree rotation of object lenses, cameras, optical glasses and other internal parts. They are designed to work under extreme pressure, temperature and velocity conditions for producing efficient output. Their construction standards ensure long time durability with minimum maintenance procedures. They can capture and record high resolution images and video with best quality enhancement and precision display. The installed cameras can work at highest frame rate per second. The optical design ensures complete elimination of chromatic aberrations, astigmatism, filed curvature, image distortion and other defects.

The basic categorization of Borescopes is done on the basis of analog and digital models. Of course the analog models have become obsolete since long. Hence we consider the digital models and group them into different types. There are various parameters like dimension, design, type of camera, probing parts and others on the basis of which we can group the Borescopes. For example the micro, mini, regular and macro size Borescopes are used for inspecting the various diameters of pipes. Rigid models, industrial probing devices, swing prism models, fiber optic models, extendible models, low cost models, remote and handheld models, mini-rigid models, lightweight and heavyweight models, short and long models etc. practically speaking you can find infinite models in use today. Here we focus on micro and rigid models with image and video capturing capabilities.

Micro Model Borescopes

  • Mode Switching: – Micro models of Borescopes are highly flexible in switching modes from camera to eyepiece mounting. Some of the models also allow combination of camera with eyepiece. You can dynamically reduce or increase the viewing, recording and magnification parameters in real time.
  • Lens Types: – The lenses used in micro models of Borescopes vary in diameter from 0.4mm to 4+mm.  The field of view angle changes from 0-degrees to 90-degrees with highest flexibility for the direction of view. Highest values for focal parameters like format, length, dimension, distance and range make the micro Borescopes flexible in design and applications.
  • Strong Body: – The external body of micro Borescopes is made of stainless steel, aluminum, brass and combination of alloys. The internal architecture is made of highly flexible working length for the pipes. The device can be inserted into small pipes and cylindrical structures with ease. The body can withstand maximum pressure from the liquids, gas and air flowing within the pipes being inspected.

Rigid Model Borescopes

The rigid models of Borescopes are best suited for industrial inspections. Their sensitivity and scanning ability makes them applicable in nuclear power plants, gas supply lines, oil wells, paint manufacturing and supply units etc. They are made from toughest forms of steel, brass, copper and combinational alloys which give maximum stability and durability.

The typical parts of rigid Borescopes are the long insertion shaft, digital prism, light condenser, light guide tube, ocular lenses, eyepiece/camera, remote control sensor, zooming devices and power supply units (ex: – battery). Usage of multiple dimensional lenses with dynamic options for lenses exchange gives the rigid Borescopes highest resolution and image/video enhancing capabilities.
