Using advanced technology, it is possible to inspect
objects fast and reliably.
Objects can be inspected for Color, Color and Shape,
Blob/Stain, Contour, Differentiation of picture, etc.
The MVS features an Optex original design LSI with CPU integrated, we
were able to integrate the vision process engine into the camera unit.
This solution provides high speed image processing and accurate
inspection for a variety of applications. Each camera processes the
image internally and transmits the result to the controller.
Reliable measurement of length and/or edge count.
Measure the distance between edges, measure the
pitch of pins, count edges, etc.
Inspection of Date, Time and Text.
Verification of Expiration date,Time stamp, Lot number
or Text.
Connect up to three cameras.
Touchscreen operation.
USB and RS232 interface.
10 key data entry.
Onboard Lighting control.
We utilized a new technology in the MVS that features low heat
generation and low power dissipation. This concept was originally
developed for the CVS series as an all-in-one design, the same
technique was carried over to the MVS.
There is no change in the response time when multiple cameras are
used. The all-in-one design allows the camera to operate independent
from the controller.
The controller has a built-in touchscreen interface, full color display and
ten-key input panel. A power supply for control of the external lighting is
also integrated into the controller. Simply connect the cameras and
lights to the controller. There is no need for a console, external monitor
or a separate power supply for lighting.
Lighting is the single most important factor to capturing a good quality
image for inspection. Optex FA offers a complete selection of lighting
options. We can provide customer support for the selection of lighting,
lenses, and training.

Each Camera can have a maximum of 16 inspection windows in
one Bank of memory. Each inspection window can be set to
inspect a different feature based on 6 inspection functions. The
inspection judgment output for each inspection window can be
output through the 50 pin I/O connector.
You can remotely select the bank to use by using a controller,
PLC or the RS-232C I/F. The setup parameters for each bank are
stored in memory and can be recalled when the product is run
again.
Lighting control without the need of a separate power supply
Controller has LED lighting control built in
PM EM OCR
Support for a total of three LED lights(12VDC, 24W total)is
available.
The output connector for the power source is a quick
connect/disconnect type.
The intensity level for each light can be adjusted separately.
For stable inspection and better process yield
5 functions are available
Continuous capture
Up to 4 inspection windows
OCR
The parameters for each inspection window can be individually
set.
Up to 2 Forms of each Date and Time are available for one
window and up to 4 Forms of strings are available(max. total of 4
Forms).
PM EM OCR
When the camera checks the image it will automatically check up to 5(EM) or 6 images(PM/OCR), looking for a good reading.
This insures stable operation if the trigger is not stable or the position of the object changes slightly. If the result is found to
be OK the inspection will stop prior to reaching the maximum number of inspections.
Variable shutter speed
PM EM OCR
When the camera is checking image using the Continuous
Capture feature the shutter speed will automatically be
adjusted up to +36% ~ -24%. This compensates for
changes in the lighting.
Scaling up/down
PM
When the camera is checking the image using the
Continuous Capture feature the image will automatically
be scaled Up/Down by up to +/-6%. This compensates for
changes in the distance between the camera and object.
The images is searched not only in the X and Y direction
but it also can be rotated up to +/- 180 degrees (PM/OCR)
or +/- 45 degrees(EM). This is useful when the position or
orientation of the object changes.

Each Camera can have a maximum of 16 inspection windows in
one Bank of memory. Each inspection window can be set to
inspect a different feature based on 6 inspection functions. The
inspection judgment output for each inspection window can be
output through the 50 pin I/O connector.
You can remotely select the bank to use by using a controller,
PLC or the RS-232C I/F. The setup parameters for each bank are
stored in memory and can be recalled when the product is run
again.

OCR
The parameters for each inspection window can be individually
set.
Up to 2 Forms of each Date and Time are available for one
window and up to 4 Forms of strings are available(max. total of 4
Forms).
PM EM OCR
When the camera checks the image it will automatically check up to 5(EM) or 6 images(PM/OCR), looking for a good reading.
This insures stable operation if the trigger is not stable or the position of the object changes slightly. If the result is found to
be OK the inspection will stop prior to reaching the maximum number of inspections.
Variable shutter speed
PM EM OCR
When the camera is checking image using the Continuous
Capture feature the shutter speed will automatically be
adjusted up to +36% ~ -24%. This compensates for
changes in the lighting.
Scaling up/down
PM
When the camera is checking the image using the
Continuous Capture feature the image will automatically
be scaled Up/Down by up to +/-6%. This compensates for
changes in the distance between the camera and object.
The images is searched not only in the X and Y direction
but it also can be rotated up to +/- 180 degrees (PM/OCR)
or +/- 45 degrees(EM). This is useful when the position or
orientation of the object changes.

Dark Compensation
Vision Sensor

EASY SETUP
PM OCR
For reliable inspection of color, the hue of each pixel is calculated. This function insures that captured images are stable
even with variations in lighting or when the distance to the target changes.
When the light is from the top
Simply follow the explanation on the display
Fast and easy "SETUP Menu"
Concept : No operating manual required
Following is example of MVS-PM SETUP Menu
1. Touch[Setup]button 7. Determine search area and its function
The MVS calculates the hue of each pixel so it can get a
homogenous color for each pixel. Regular vision sensors simply
adjust the brightness so the upper part is brighter than the lower
part.
When a bright ambient light is present
The MVS can get a homogenous color for each pixel even if the
object has an area which is brighter due to external ambient
light.
When the distance varies
The Dark Compensation function is effective when the object
distance varies and its brightness changes.
When the object is glossy
The Dark Compensation function helps to reduce bright spots on
glossy surfaces.

Stain
Vision Sensor
15 16
The camera compares the differential ratio of the stored master
image with the differential result of the target image to
determine the Stain value.
When this value exceeds the upper limit or is less than the
lower limit, it is defined as NG.
This is used to detect the presence of stain (flaws) on the surface
of metal objects or defects in plastic materials.
Contour
The camera compares the contour of the stored differential
master image with the contour of the target object. It counts the
number of pixels that do not match the Target contour to
determine the Contour value (Lack of pixels). It counts the
number of pixels outside of the Target contour area (background)
which have the selected color to determine the Stain value.
If either value exceeds the threshold, it is defined as NG. This
function is used when the contrast of the target object is high
and inspecting the contour produces a more accurate result.
Differential
The camera compares the stored differential master image with
the target object. If the difference exceeds the threshold it is
defined as NG.
This function is used to inspect metal parts with uneven lighting.
It is not good for detecting color or its depth.
Color Shape
The camera inspects the shape of the area that contains the
selected color.
It counts the number of pixels that have a different color in this
area to determine the Contour value (Lack of pixels). It counts
the number of pixels outside of the area (background) which
have the selected color to determine the Stain value.
If either value exceeds the threshold, it is defined as NG. This is
used when the target color is close to the background and is
difficult to inspect by its contour or differential image. This is not
good for checking black and white objects.
Color Area
The camera calculates the ratio of the number of pixels that
have the selected color to all the pixels in the inspection window.
When it exceeds the upper limit or is less than the lower limit, it
is defined as NG.
This is used to detect color differences, especially when the
color is not stable and that there is no need to detect object
shape.
Full Color
The camera will compare the difference between the full color
image of the target and the stored image.
If the sum of the difference exceeds the threshold value it is
defined as NG.
This is used to inspect color and depth of pictures and prints
under stable lighting.
Inspection for Color, Flaw, Blob, Shape, etc.
