Features & Benefits
Inspect by viewing images from areas
Invisible to naked eye
Cavities difficult to access may be easily
and accurately observed
Can be inspected During Normal Downtime

Rigid Borescopes
RIGID BORESCOPES
Combines Conventional Lenses With Short Optical-Glass Rods
Rigid Borescope - Dimensions
Wide range of Diameters & Lengths
1.6 mm to 10 mm Diameter
50 mm to 1500 mm Length
Choosing A Borescope
Choose by physical Trials with the Component
Choose Diameter, Length, Viewing Angle & Field of View for
Optimum Selection.
Borescope must allow "wiggle room” inside the hole
Too Small Dia may not give Sufficient Area of Coverage
Choosing A Borescope
Diameter: 3.3 mm Borescope will be optimum for 5 mm Bore but
may not be optimum for a 12 mm bore where 8 mm will be
optimum
Length: Choose a Borescope to penetrate to the greatest depth
required, but not so long as to be unwieldy outside the hole
Direction-of-View (DOV)
Axis of the center to the field-of-view
Direction-of-View (DOV)
Direction-of-View (DOV)
Object straight ahead - 0° DOV might be Best
Object very close to the entry port (Engine Valves near a
spark plug hole) a backward-looking 120° Borescope might
be Best
When examining a bore, like a rifle barrel, a 90° DOV will
be perfect.
Field of View
Measures the Visible portion of an Image
A Measure of Depth of Field
MAGNIFICATION - 1
MAGNIFICATION- 2
Very large Depth of Field — From infinity down to an inch or less
Makes them easy to use without constant
refocusing
closer an object to the lens ◊ greater the magnification

Flexoscope, Fibroscope or Fiberscope
Flexoscope
Operation of the Flexoscope or Fiberscope
Imaging Remote Areas using Optical Fibers
Optical Guide - illuminate Object
4 way or 2 way Articulation
Basic optical fiber components
Fiber structure
Central core & Outer Cladding or Mantle
Core has higher index of refraction &
Cladding * lower Refractive Index
One Factor Enabling Image transmission with Clarity
And Possibility of Fibroscope
Flexoscope - Glassfiber Bundle & Image Transmission
Flexoscope - Flexoscope Distal End or the TIP
Flexible Fiberopticscopes or Flexoscopes -
Special Packing Technology Allows More Fibers
Enabling Sharper Images
Flexoscope - Durability
4 layers of protection
2 stainless steel coil layers for Mechanical
strength
One vinyl/PVC layer allows utility in fluids
External Stainless Steel Outer Braid Mesh layer
for Wear Resistance
Flexoscope - Important Features
Eyepiece Focussing
Plastic Outer Coating : 0.5 mm to 3.5 mm & 5 mm
Stainless Steel Braid Mesh Layer - 4.2 mm, 6 mm, 9 mm & 12 mm
2 Way & 4 Way Scope Articulation
Temperature Resistant Upto 80º C
Flexoscope - Bending Radius
SMALL BENDING RADIUS IMPROVES MANEUVERABILITY & AVOIDS DAMAGES
Flexoscope - Tip Articulation
2-way or 4-way scope articulation
Improves Tip Maneuverability
Reduces inspection time

Aircrafts - Endoscopic Visual Inspection
Endoscopic inspection shortens aircraft down-times and safely detects any necessary servicing procedures.
Commercial industial endoscope sets suitable for all common engines used worldwide.
The United States Air Force has Qualified and Approved the TechnoPack X Videoscope System for Borescope Inspections, including measurement.
Aircraft Turbine Inspection
POWER, PETROCHEMICAL AND PLANT MAINTENANCE
Endoscopic systems make it possible to see inside turbines, Pipelines, rotating equipment, Pumps, condenser tubes, heat exchangers, confined spaces, feedwater heaters, boilers, headers, valves, pressure vessels and other difficult to see areas.
Checking for pitting, cracking, corrosion, erosion, weld and other defects
Endoscopic Visual Inspection of Vehicles
Manufacturing - water test - engine build - HVAC · Engine - valve damage, cylinder inspection, head gaskets
and piston top · Transmission and Differential - ring, bevel gear inspection
- seals and shaft bearing inspection · Clutch - condition and thickness of lining - condition of
springs of pressure plate and thrust bearing · Body and Chassis - inspection of hollow members to
detect damage cracks and corrosion · Miscellaneous - fuel tank inspection - manifold inspection -
HVAC forensic evaluation
Visual Inspection Automotive Engines & Other Parts
Endoscopic Inspection of Foundry Castings
CCD - What is it ?
Used in what are known as CCD camera
Special Piece of Silicon Called a Charge Coupled Device
or CCD
This silicon wafer is a solid-state electronic component, which
has been micro-manufactured and segmented into an array of
individual light-sensitive cells called "photosites."
Each photosite is one element of the whole picture that is
formed, thus it is called a picture element, or "pixel."
