energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case
the user will be required to correct the interference at his own expense.

CAUTION: Changes or modications to this device not

expressly approved by Cohu Electronics could void the
user’s authority to operate the device.

3610 CAMERA

1.0 GENERAL DESCRIPTION

This introduction briey describes overall

characteristics of the Camera (gure 1) related to

its installation and operation.

1.1 Electrical Characteristics

The 3610 Series provides a small, light­weight, highly sensitive machine vision CCD
Camera with all electrical connections via a single
rear panel connector.

Setup and control settings are implemented
by a graphical user interface (GUI) communicat­ing through an RS-232C serial interface with the
Camera.

The Camera operates in either NTSC or PAL
format depending on the model. This Camera op­erates at an internal clock rate of 28.63636 MHz
(NTSC) or 28.375 MHz (PAL). Table 1 lists speci­cations for this 3610 Camera.

Table 2 is a list of major features of the Cam­era — primarily those associated with the GUI.

The Camera is available in two different

operating power congurations: 5 V dc and 12 V

dc. Only manual iris lenses can be used with the 5
V dc Camera. The 12 V dc Cameras are available

in three congurations: (1) an auto iris version

(2) a dc iris version or (3) a freeze frame version
— which requires the use of a manual iris lens.

Manual iris versions of the camera can be
optioned for horizontal and vertical drive inputs If
these inputs are not used the camera operates in
standard crystal sync reference mode.

1.1.1 Sensor Characteristics

Figure 2 shows the relative response charac­teristic of the three sensor sizes available for this
camera. These characteristic curves apply to both
NTSC and PAL sensors. The curves show Cyan,
Green, Yellow and Magenta responses.

These graphs exclude both the lens charac­teristics and the light source characteristics.

Note however that the IR cut lter shown in
gure 3 will modify the overall response of the
Camera to light. This low pass lter starts block-

ing light above about 500 nanometers and at 600
nm passes only about 50 percent. Rolling off the
response at these longer wavelengths minimizes

the effect of infrared on the color response of the
Camera.

1.2 Mechanical Characteristics

A model number interpretation diagram ap-

pears in gure 4. This diagram shows the various
basic congurations of the Camera.

Dimensions for the Camera are shown in g-

ure 5. Figure 6 is a detailed dimensional illustra­tion for the optional mounting block that provides
threaded 1/4-20 mounting holes. The Camera
consists of a main body casting and front casting
assembly.

Interconnections are via a 12-pin connector

located on the rear panel.

An adjustable CS-mount adapter threads
onto the front of the casting. It is secured from
turning by a nylon tipped hex-socket head set­screw.

The Camera can be mounted at any of three
places on its body:

1. By the CS mount directly to a microscope or
other similar device

2. By the top of the case — either with or without
the optional mounting block

3. By the bottom of the case — either with or
without the optional mounting block

Directly mounting to the top or bottom of the
housing requires removal of the two black button
head screws holding the outer housing cover in
place at that location (top or bottom). The op­tional Accessory Kit contains the mounting block
and a pair of 2-56 × 3/8 stainless steel screws to
attach it to the Camera.

If the Camera is to be mounted directly with­out use of the optional mounting block, a pair of
2-56 stainless steel screws of the required length
would have to be acquired. These are not sup­plied.

Note that special-order Cameras and Camer-

as modied for special purposes may be shipped

with other items. The above listing are the basic
items for typical applications.

Table 3 lists the basic items supplied with a
Camera. Table 4 lists items supplied in an optional
accessory kit.

2.3 Equipment Required but Not
Supplied

If the following items were not ordered with
the Camera these will be required to make it op­erational:

Characteristics

1. CS- or C-mount lens suitable for the sensor
format/size in Camera

2. Power supply, 5 V dc, 500 mA output or 12 V
dc, 350 mA

3. Cable. Refer to one of these test cables as an
example for the construction of an interconnec­tion cable to be used with the Camera:

a. See gure 8 for use with a 5 V dc (manual

iris) versions of Camera. This cable shows
connections for the H and V drive option.

b. See gure 9 for use with auto iris or dc

iris version of Camera (12 V dc operating
power).

c. See gure 10 for use with a 12 V dc Cam-

era optioned for freeze frame operation.
(Requires use of a manual iris lens.) This
cable shows connections for the H and V
drive option.

4. 1/4-20 mounting bolt(s) of the proper length if
the mounting block is to be used.

2.4 Cabling Requirements

A single 12-pin connector (gure 7) on the

rear panel provides all electrical connections to

the Camera. Table 6 lists the mating cable plug for
this rear panel connector. Use this plug to con­struct the cable for operating the camera.

Several test cables are shown in this manual.
They can be used as an example for wiring the
operating cable for a Camera.

Figure 8 shows the wiring arrangement for a
5 V dc (manual iris only) version of the Camera.
This cable provides for all operating capabilities of
a 5 V dc Camera.

A 12 V dc version of the Camera may require

a cable wired to either of two congurations. One
is for use when the Camera is internally cong-

ured for use with either an auto iris lens or a dc iris
lens. The other is for use when a 12 V dc Camera

is internally congured for freeze frame operation,

and/or external horizontal/vertical drive options.

1. Figure 9 shows the cable for use when a 12

V dc version of the Camera is congured for

either an auto iris lens or a dc iris lens.

2. Figure 10 shows cable wiring for use when

a 12 V dc Camera is internally congured for

either freeze frame operation or H and V drive.
Only a manual iris lens can be used when the

Camera is congured for either freeze frame

operation or H and V drive.
