Super Thin Fiberscopes Inspect the Smallest Areas

Super thin fiberscopes are used to remotely inspect the smallest areas. 
Sometimes applications require access through the smallest holes less than 1.0 mm. Typically these super thin borescopes are limited in length and direction of view is forward.
These small inspection areas provide remote visual inspection professionals with many challenges. The access dictates the inspection requirements more than any other factor. The smaller the inspection area the more limited the choice of borescopes available and the number of manufacturers of these micro borescopes.

Applications for Micro Borescopes:

• Engineering  Manufacturing. Super thin Fiberscopes provide cost-effective examination of internal structures without tear down.

MEDIT's Micro Borescope• Quality Control. Super thin Borescope instruments allow manufactures to inspect components for defects. Mini borescopes provide the ability to inspect internal components, bore holes, castings and other manufactured items such as turbine blades, automotive components, circuit boards, rifle barrels and welds.

• Castings. Super thin Fiberscopes can be used to inspect inside casting of engine blocks and other high quality casted components.

At you can find a full range of micro borescopes for remote visual inspections.

LED light sources for Endoscopes

LED light source with a borescope

No wonder today innovations touch every area of our life.  
The best and most useful discoveries are devoted to cure and save people. LED light sources stand out of this long list. What can be more familiar to us than a usual bulb? For decades we have used simple electric bulbs, but now they are rapidly being substituted by new LED bulbs.
What is a LED? LED – light-emitting diode – consists of a semiconductor diode. LED was discovered yet in 1927 by Russian scientist Losev, but enjoyed its practical application only in 1962, when the production of red light emitting diodes launched. One of the first LED indicators was used in calculators in 1968.

Gradually LED light sources penetrated into many spheres of industry and medicine.  Scientists developed new very bright light sources based on super efficient  LED bulbs, which at a higher current emit thousands of lumens. Now we can say that LED light sources have more advantages than any other, including Halogen or Metal Halide light sources. 

LEDs produce more light per watt than other bulbs. Just with the help of 3V battery you can receive power of a good multiwatt bulky Halogen light source.

LED light source for borescopeLEDs can emit light of an intended color without the use of color filters. Now LED handles for endoscopy emit a very powerful white light. This light is “cleaner” and “whiter” than Halogen and stands near Xenon light sources, which helps at the most complex operations.

LEDs can be very small (smaller than 2 mm). Based on this feature LED light sources (or LED handles) become more and more compact. Their weight is getting less. Everything is handy. You can easily take it and adjust light intensity and focus just with a slight touch of finger!
LEDs light up very quickly. You don’t need to wait long for the efficient work. The brightest light starts emitting in microseconds, and often these very microseconds can be decisive.
LEDs can very easily be dimmed either by modulation or lowering the forward current. Now LED light sources get a light intensity switch to decrease or increase illumination easily.
In contrast to most light sources, LEDs radiate very little heat in the form that can cause damage to sensitive objects or tissues. Wasted energy is dispersed as heat through the base of the LED. 
LEDs can have a long useful life. One report estimates 35,000 to 50,000 hours of useful life, though time to complete failure may be much longer.
LEDs, being solid state components, are difficult to damage with external shock.
The solid package of the LED can be designed to focus its light. Incandescent and fluorescent sources often require an external reflector to collect light and direct it in a usable manner. This feature results in LED light sources with adjustable focus. This helps to illuminate either a large are of inspection, or to concentrate on a small spot.
The development of LED technology has caused their efficiency and light output to increase exponentially, with a doubling occurring about every 36 months since the 1960s, in a way similar to Moore's law.  Soon LEDs will completely substitute all the other light sources.

Does My Borescope Need a Camera?

ImagePRO TV borescope camera
Optical borescopes and fiberscopes can record video with the help of a CCD camera. The CCD camera is attached to the eye piece of the borescope with a C-mount video coupler. You get a very convenient device - both for optical (eye) inspection or to view the video on a TV monitor.
Sony CCD borescope camera
Various adapters can transform analog signal to digital. They are so called Image Capturing devices or boxes. With the help of such a set - Fiberscope + CCD Camera with a coupler + USB Capturing device - Inspections can be viewed and recorded on a laptop.

For more information about borescope cameras see this page, or please email me.

Borescope Application at Power Plants

During maintenance works at Electric Power Plants borescopes sand videoscopes are used to reduce maintenance costs and avoid outages. Videoscopes can be used in the following areas:
  • Steam and gas turbines - turbines are checked for foreign object damage, erosion, burning and cracking. Combustion chambers are inspected for cracks, combustion deposits and burning. Turbine section nozzles and blades are checked for cracks and erosion.
  • Heat Exchangers - cooling tubes are checked for scale deposits, corrosion and cracking.
  • Boilers are remotely inspected with long videoscopes. 

For more information on videoscopes using at power plants go here, or email me

Borescope LED Light Source - New and Innovative

LED Light source for borescopeAs a skilled professional looking for the best tools for remote visual inspections, the Xtreme LED is exactly what you need. Essential improvements include - portability, as there are no cords to plug in unlike metal halide light sources, increased illumination with 50,000 Lux, higher then any other 3W light sources and bright enough to use with most flexible fiberscopes.

Borescope light source with a chargerProfessionals often meet situations when the weight of equipment is vitally important. The Xtreme LED light source is the best solution at such complex tasks, as high-altitude works, field works, areas without electricity and others.

The Xtreme light source can be widely used under severe climate conditions, where other light sources cannot be operated. One of the most important features of the Xtreme LED light source is a very durable LED bulb with practically endless resource (over 1,000,000 hours of lamp life per bulb) unlike HID or Halogen bulbs.

Borescope Field of View - What? Why? How?

Borescope field of view
It is important to understand some terms when choosing the right inspection tool - borescope. The field of view (FOV) is the angular extent of the observable inspection area that is seen at any given moment. Borescopes, fiberscopes, videoscopes and other remote visual inspection equipment should all list field of view in their specifications.
A wide field of view allows conducting a turbine inspection to complete each section in one pass while a narrow field of view may require the inspector to inspect the same section of turbine blades twice and take more time to conduct the inspection.
It is also worth attention to evaluate how a different field of view affects the depth of field (the distance from the target a clear image can still be seen). Typically, the wider the field of view a borescope has, the shorter the depth of field.
