Chapter 1 Introduction

1.1 Description

The Thorlabs VSD500 Visual Scratch and Defect Detection system enables users to examine the connector end-

face and fiber for permanent defects (such as scratches, cracks, and pits) and transient defects such as loose

contamination (dirt, oils, water, and cleaning solvent residues), complementing the interferometric end-face

geometric inspection of the existing Thorlabs CC6000 and GL16 product lines. Visual end-face inspection occurs

between each polishing step of a fiber optic cable manufacturing process. Initial criteria may be removal of epoxy

and chips caused by cleaving, later inspection criteria may include removal of scratches or pits from the fiber and

clear delineation of epoxy and cladding.

Chapter 2 Description

2.1 How it Works

The VSD500 Visual Scratch and Defect Detection System is a standalone device with fully embedded control

hardware and software. It uses precision optics and a camera coupled with Linux-based software, delivering a

clear image of a connector endface when inserted into the front panel fixture. Manual X-Y positioning of the

connector is possible with adjustments at the fixture, allowing for viewing of fiber as well as ferrule areas of the

endface, and in this way accommodating various fiber sizes. Manual focusing of the endface being tested can be

performed usingthe front panel FOCUS adjustment. The VSD500 field of view is optimized for the standard 125 micron

fiber diameter, with a fixed magnification of 640x onto its front-panel 8” LCD screen.

•The integrated software enables performing various operations relating to the displayed endface image,

including automatically detecting any scratches and defects on the endface, comparing the detected

information against user-selected pass-fail criteria, generating and presenting inspection reports and

images to screen and file, and supporting export of that information to removable USB storage. General

system configuration is also possible such as inspection criteria definition and options for storing image

files to disk. VSD500 configuration is saved by the software at shutdown and reloaded at next startup. All

software functions are accessible via a set of five pushbuttons on the front panel (with each button’s

changing function indicated by adjacent button labels displayed on the LCD screen) and also a separate

front panel pushbutton for activating an inspection. The VSD500 can be shutdown as well as restarted via

another front panel button.

2.2 Mounts

The VSD500 supports inspection of the standard range of single-fiber connectors, with mounts available for

products having ferrule diameters of 1.25 mm or 2.50 mm, and with flat, PC, or APC endface polish. Each mount

is positioned and held securely in the front panel mount holder magnetically. Insert the mount into the holder

with its flat side facing the holder’s opening as it is slid in, as shown below.

2.3 Features

In addition to its core functionality, the VSD500 system has also been designed with some unique features that

improve its usefulness and ergonomics, as follows:

•The system can be operated with the fiber holder on the left or the right side, simply by flipping the entire

unit to the desired orientation. When changing the orientation, the power must be cycled in order for the

User Inteface to display correctly.

•The unit rests securely on a custom platform that tilts the front panel at an easier viewing angle.

•The system will start up via the rear-panel on-off rocker switch, or via the shutdown/restart pushbutton

on the front panel (when the rear panel power rocker is already at “On” position).

•The front panel USB port is ready to receive a USB drive for exporting stored files or for software updates.

Any of the rear panel USB ports can be used for this purpose as well.

•The three USB2.0 ports at the rear panel are intended for connecting a keyboard, mouse, or barcode

scanner, while the video port on the rear accepts an HDMI

cable and enables the use of an external

monitor to mirror the front panel display.

NOTE: The connection to an external HDMI monitor should be made using a commercial grade

high-speed HDMI cable with ferrite cores.

•A keyboard and mouse, if connected, can be used as an alternative to the front panel 5-button array for

navigating and activating the menu functions, as well as for naming files or detection criteria

configurations.

Chapter 3 Quick Start Guide

3.1 System Preparation

Upon receipt of your VSD500 system, the following steps should be followed in order to put it into operation.

•Remove the VSD500 unit, tilt platform, AC adapter, and any provided fixtures from the shipping container.

•Remove the VSD500 unit from its protective bag and ensure that its rear panel power rocker switch is in

the OFF (“0”) position.

•Position the supplied tilt platform on the bench where it is intended to be used, and place the VSD500

unit onto the tilt platform in the desired orientation (with the connector fixture on the right or the left).

•Locate the DS12 12 VDC, 4 A desktop AC adapter used to power the VSD500 system. Plug the 4-pin circular

connector end of the AC adapter into the VSD500 rear panel 4-pin power jack.

•Connect the supplied AC power cable to a properly-filtered AC outlet and the DS12 adapter.

•If desired, other USB devices can be attached as well (e.g.: keyboard, mouse, barcode scanner, USB drive)

at this time.

NOTE: If the unit has recently come from an environment more than 10 °F colder than the

current room temperature, allow at least 3 hours for it to acclimate (outside of its shipping

container) before applying power. Not doing so may damage sensitive optical components in

the system.

•When ready to start using the system, set the rear panel power rocker switch to its ON (“1”) position. The

system will start up, presenting the main user interface.

Figure 3 Rear Panel

•Load an appropriate type of connector mount into the front panel mount holder.

•After loading the mount, turn the X-Y adjusters so that the light at the mount aperture is maximized.

Caution

Though the LED is of lower power, it is recommended to not look directly into the aperture when

the LED is set to ON.

•Clean and fully insert a connector into the connector mount.

•In the VSD500 main menu, turn on the Overlay Tools. This will enable a software function that assists the

user with fiber centering and endface focusing in preparation for a future inspection. A scale is also added

to the Live View window for manual gauging of the size of any artifacts observed in the view.

•Perform any system software configuration, such as Save Options for image storage, that may be needed

(see Chapters 6 and 7 for more information).

•Center the fiber and focus the image using the Overlay Tools.

•If desired at this time, press the front panel CAPTURE button to initiate an inspection.

•When ready to shutdown the VSD500:

oPress and hold the front panel red momentary pushbutton for at least 3 seconds. This will put

the system in standby mode from which it can be awakened later by pushing the same button

again.

oTo fully power down the VSD500 after it is in standby mode, set the rear panel power rocker

switch to its OFF (“0”) position.

NOTE: Safe shutdown occurs by first placing the VSD500 in Standby Mode via the front

panel Red power button. It is not recommended to set the rear panel power switch to OFF

while the unit is still in operation.

3.2 Package Inspection and Unpacking

3.2.1 Inspection

When your system arrives, check the shipping cartons for wrinkled or damaged corners, holes through the

cardboard or other signs of rough handling or abuse. If you find any signs of damage, insist that the delivery service

make a note describing the damage on the delivery receipt.

NOTE: If your system arrives in very cold weather, allow the boxes to warm to room temperature

before opening them. Exposing a cold unit to a warm room causes condensation that could damage the

system. If condensation forms, wait for the unit to dry completely before setting it up and connecting it

to an electrical outlet.

3.2.2 Unpacking

Your system is shipped as a single shipping box containing containing the instrument, manual, power supply,

power cord, mounts, and stand. Carefully open the box, making sure not to puncture it too deeply if using a box

cutter. Remove the items in the box very carefully.

3.3 Maintenance

The VSD500 system is reliable and robust, requiring minimal maintenance. The primary components needing

periodic care are its front panel screen and whatever set of connector mounts were provided as standard or

ordered by the end user.

3.3.1 Cleaning the System Enclosure, Screen, and Mounts

Use a damp, lint-free cloth to clean the system’s enclosure. Avoid, at all costs, abrasives or solvents as they can

permanently damage the finish. For the screen, a mild glass cleaner on lint-free cloth can be applied periodically

to remove debris.

While a mount is not attached to the VSD500, check it for evidence of any dust or dirt collected on or inside the

mount, and use compressed air to blow off particles. An alcohol wipe can be usedonthemounts if excessively dirty.
