Milliscope II
• Available Diameters 0.4 To 4.0mm
• Available Lengths Up To 5 Meters
• Probes Are Interchangeable With Back-ends
• Can Be Used With Any Existing Light Source
• Can Be Used With Any Existing CCD Camera
(1/2 Preferred)


Milliscope Options
• Rigid, Flexible Semi Flexible
• 0°, 16°, 30°, 70°, 90° And 100° Direction Of
View
• Milliwand Option
• Mirror Tubes
• High Magnification Back-ends
• Ocular Viewer


Optional Optical Viewer

•Not required since most applications rely on video for better results,
documentation and ease of inspection
•Threads onto the back of the back-end


Back-Ends
Dark Back-End Lighted Back-End

Dark back-end is required for 1.0mm and smaller.

Lighted back-end may be used with larger scopes for easier interchangeability.

Lighted back end yields approximately 30% less light output. This is due to the
break in the light fiber.


Lighted Body Back-End


Continuous Light Guide (CFL)

•Yields most illumination by having no breaks in the fiber optic
light guide.
•Can be used with either a dark or lighted back-end

Milliscope II Without Continuous Light
Guide

•Maybe larger than 1.0mm rigid or flexible
•Do not with with a dark back-end


Lighted Backend With Scopes

•Works with flexible, rigid or semi rigid
•Only attaches one way to ensure light guides line up
•Larger than 1.0mm in diameter
•Superior design when frequent scope changes are being made

Dark Back-End with Scopes

•Scope must have its own internal continuous light guide to provide
sufficient illumination
•This is superior to other designs that require and attach light guide and
lose illumination

Rigid Milliscope


Flexible Milliscope


Milliwand or Pencil Probe

•Perfect for repetitive inspections
•Superior solution than having CCD sitting on top of scope


Side View Mirror Option

•Affordable side view option
•Does not offer the resolution of a Prism

Multiscope
• Rotational Rigid Borescopes
• Shaped Rigid Borescopes
• Pencil Probes


Multiscope Back-End

•Includes a lighted back-end quick release design for Multiscopes
•Allows for 360° rotation of side view scopes without tangling light
guide
•Multiscopes do not fit into Milliscope back-ends and vise versa


Wide Variety Of Multiscope Designs


Multiscope Pencil Probes


Shaped Multiscopes


360° Rotational Side View Rigid
Borescopes


Flexible Multiscopes


When Do You Choose A Milliscope
Versus A Multiscope?
• Typically You Will Choose A Milliscope Design
• Multiscope is Useful For:
1. Rotational Requirements
2. Existing Multiscope Platform
3. Special Shaped Probes
4. Multiscopes tend to be larger diameter, i.e. 1.0mm and larger

Interchangeable Light Guide Posts

•Milliscopes work with any existing light source
•Zibra incorporates a protective glass rod in post to prevent burning from 24
watt Lamps Advanced Inspection Technologies

24 Watt Light Source

•Very powerful white light. Works well with milliscopes
•Lamp life 350 hours and lamps cost $290.00
•Burns a hole in most light guides with time
•$1,050.00 Advanced Inspection Technologies

50 Watt LED

•Very powerful white light. Works well with milliscopes
•Cost effective because no replacement lamps are needed
•Typically not as well focused on light guide
•$1,350.00


Universal CCD Cameras

•C-mount CCD cameras are industry standard
•Zibra scopes will fit into existing CCD cameras
•Other borescopes will connect to zibra CCD camera


CCD Camera


Analog and Digital CCD Cameras

Video Signal Is Transmitted Via Composite Or S-video Cable To Display


Analog Display Options

•Standard LCD Monitor
•3.5 Inch LCD: Battery, Records Video And Stills
•Customers Existing Displays
•Itool Image Hub

*Be aware that customers using outdated displays do get the full advantage of
high resolution scopes and CCD cameras

Digital CCD Cameras

•Video Is Transmitted Via USB Cable
•Software Download Is Required
•Capture Stills And Video
•Image Enhancement Features Are Available That Analog Camera Does
Not Offer

Mounting Options

Magic arms and table top tripods should be
used to mount the CCD camera for stability
of the system.

Borescopes 101: Basic Concepts
• Image Guide
• Light Guide
• Fiber Optic Image Pixels
• Rigid Borescopes
• Semi Rigid Borescopes
• Flexible Borescopes
• Quartz Fibers Versus Leached Image Guide
• Bending Radius
• CCD Camera
• C-Mount Fitting
• Color Temperature
• Depth Of Field
• Field Of View
• Direction Of View


Fiber Optic Image Guide
Fiber Optic Light Guide
•Glass like fibers that transmit light through individual fiber
optic strands
•Image guide requires that the individual fibers be aligned or
coherent
•Each strand is approximately 10,000 microns (about 1/10th the
size of a human hair)
•An image fiber bundle may contain as many as 30,000
individual fibers or pixels
•Broken fibers are seen as black dots on image

•A fiber optic light guide can be randomly aligned
•Broken fibers may result in weak light output


Rigid, Semi Rigid or Flexible?
• A True rigid borescope is made with a gradient
lens system or Object lens System – Will be
damaged with bending
• A Semi Rigid borescope is manufactured with
a fiber optic bundle and will allow some
flexing before breaking
• A flexible borescope is manufactured with
either a quartz or leach fiber optic image
guide and has a significant bending radius


Quartz Versus Leached Image Guides
• Leached image guides have a greater bending
radius and tend to be more durable than quartz.
Typically found in our 2.4mm ITC fiberscope.
• Quartz image guides have a reduced bending
radius and offer greater resolution than a leached
image guide. Typically found in small diameter
fiberscopes.
• Bending radius is the radius that a flexible scope
can be bent before damage occurs to the scope.

Video Knowledge
• Charged Coupled Device (CCD)
• C-mount lenses provide a male thread which
mates with a female thread on the camera.
• Color temperature is measured in degrees Kelvin.
The sun is 6500K which produces a brilliant white
light and perfect to distinguish colors and fine
details. A high color temperature light source is
needed for acceptable video quality with small
diameter Borescopes.

Borescope Optics
• Depth of Field: The tip to target distance a
borescope remains in focus
• Field of view: The Area of view that extends
from the borescopes objective. A wider FOV
may let you see larger areas, however, it will
decrease the depth of field and may require
additional illumination.
• Direction of View: Where the Borescope sees,
i.e. forward, side, oblique or a specific angle.
