1INTRODUCTION
DVC Company, based in Austin, Texas, is a manufacturer of cost-effective, high performance digital video
cameras. We thank you for purchasing from the DVC-1412 product series.
This series of cameras is based on the premise that precise image processing applications demand mega-
pixel cameras that are optimized for the performance available from today’s leading-edge CCDs, while
maintaining an acceptable price to performance ratio.
The 2/3” interline Sony ICX285 CCD imager used in the DVC-1412 cameras has a 1392(H) x 1040(V)
progressively-scanned image format and has a pixel size of 6.45µm x 6.45µm. The CCD sensor has a
particularly high QE in the blue-green region of the spectrum resulting in higher sensitivity for most
applications.
The DVC-1412 series of cameras includes non-cooled, cooled, intensified, and multi-spectral versions.
Furthermore, a choice of I/O options is available: LVDS, CameraLink, or FireWire. Standard camera
features include high-speed shuttering, long-term integration, pulse driven integration, and gain/offset
control. All DVC cameras come with a standard 2-year warranty and use industry-standard “C-mount”
lenses.
This camera series also includes Intensicam II, which utilizes a gated, Gen III image intensifier, fiber-
optically coupled to the CCD.
With the LVDS version, the 10 frames/s video data is provided in a 12 bit parallel, differential LVDS
format, which is "plug-and-play" compatible with industry-standard image processors. The digital data,
pixel clock, enable line, and enable frame signals are accessible via the DB-44 connector.
The CameraLink version transmits 10 frames/s, 12-bit data over an industry standard MDR-26 interface to
any CameraLink compatible frame grabber.
In the FireWire version of the camera, the LVDS output is replaced by an industry standard 1394A
interface. The camera provides 12-bit data at 10 frames/s when used with any OHCI-compliant FireWire
interface card.
Computer-based control of gain offset is provided to "tune" the dynamic range of the camera to the
application. This provides an optimum match between the dynamic range and sensitivity of the camera and
the requirements of the application.
The CCD is physically mounted in the cavity of a high-precision opto-mechanical plate for excellent
mechanical stability. vibration applications. An adjustable C-mount coupling allows critical system
focusing adjustments. In-camera digitization using the stable CCD pixel clock eliminates pixel jitter,
improves repeatability, and enables sub-pixel accuracy in image processing applications.
DVCView, a Windows GUI software package is supplied with the camera, allowing image viewing and
control of all camera operations. Five user programmable, single-click software “buttons” allow the user
to customize the camera to the imaging application.
This manual applies to all of the DVC-1412 cameras.

3MAINTENANCE
3.1 IMPORTANT WARRANTY INFORMATION
There are no user-serviceable parts inside the camera. Removing the rear cover of
the camera without express authorization from DVC Company may void the camera
warranty.
This camera contains sensitive devices that can be damaged by static discharge. Use appropriate
static control methods when handling the camera. Avoid contact with connector pins when cables
and plugs are removed.
Depending on the model, your DVC camera may contain a glass, infra-red blocking filter to
prevent infra-red light from reaching the CCD sensor. This filter is integral to the lens mounting
ring and it also protects the CCD sensor faceplate or other optical components from contamination
and direct contact.
DVC cameras are manufactured in a clean environment, and each camera is thoroughly tested prior
to shipping to ensure that it meets our stringent specifications for cleanliness and quality. However,
accumulation of dust on the camera optical surfaces in the customer application are not covered by
warranty.
To ensure optimum image quality with any DVC camera, do not remove the protective lens-mount
cap until ready to mount the camera on the application. If the camera is removed from the
application, immediately replace the cap. Doing so will keep dust and other contaminants from
accumulating on the optical surfaces. In addition, please note the following model-specific
guidelines.
3.1.1 Intensified Cameras
The image intensifier is a delicate electronic device and can be permanently impaired by exposure
to excessive light. Damage to the intensifier due to overexposure is not covered under warranty.
Never run an intensified camera if it is not attached to an optical system, and always check
illumination levels carefully before activating the intensifier and increasing the intensifier gain.
Finally, follow cleaning guidelines outlined in section 3.2.3
3.1.2 TE-Cooled Cameras
The DVC Thermoelectrically-cooled cameras contain the CCD in a sealed, gas-filled chamber
having an anti-reflective glass window. Do not, under any circumstances, loosen or remove the
inner glass window from a cooled camera. Doing so will void the warranty. If it is suspected that
the seal has been broken or if the window breaks, do not apply power to the camera. Moisture may
have been introduced, and cooling in the presence of moisture will cause condensation and frost on
the CCD. Call DVC Customer Service. Otherwise, follow the cleaning guidelines in section 3.2.2
3.1.3 MultiSpectral Cameras
Unless specified otherwise, DVC multispectral cameras do not utilize a separate infrared filter.
When the lens is removed, it is possible to contact the filter surfaces and the filter wheel assembly.
Use precaution when changing filters and follow the installation and cleaning procedure in section
7.10.3.4.
Because the filter wheel takes up a portion of the fixed distance between the C-Mount mounting
surface and the image plane, care should be taken to ensure that the rear element of any lens to be

8
used does not protrude into the filter cavity, which may cause damage to the lens, filter, or filter
wheel. See section 7.10 in this manual for more details.
3.1.4 Standard Cameras
While the lens mounting ring and locking flange allow the user some lens back-focus adjustment,
complete removal of the ring will expose the CCD faceplate and will likely cause debris to
accumulate on its surface. Extreme care should be taken to avoid completely removing the lens
mounting ring and exposing the CCD faceplate unless absolutely necessary. Fingerprints or
other evidence of contact with the CCD faceplate may void the warranty.
3.2 Cleaning Guidelines
Frequent lens changes, especially without careful attention to contaminants, can allow debris to
accumulate on the infra-red blocking filter and lens surfaces. Therefore, DVC Company provides
the following guidelines for cleaning those components.
3.2.1 Cleaning the lens or optical assembly
Please follow the manufacturer’s recommendations for cleaning. DVC Company is not responsible
for any damage caused to the lens or optical assembly caused by customer cleaning or misuse.
3.2.2 Cleaning the infra-red filter (Standard and TE-Cooled Cameras)
The infra-red filter is visible when the lens is removed, mounted inside the lens mounting
ring.
3.2.2.1 What must I do before cleaning the infra-red filter?
Do not remove the filter from the camera.
First, remove the lens and carefully examine the filter in a clean location under a
strong, direct light. Try to determine if the contaminants are a few dust particles,
oily smudge (such as fingerprints) or both.
3.2.2.2 What if the contamination is only a few dust particles?
Use a CLEAN, DRY (preferably brand-new), camel hair lens cleaning brush (such
as those used by photographers) to gently wipe the particles off of the filter.
3.2.2.3 What if the contamination includes a smudge?
The filter is a high-quality, coated optical component and should be treated with
extreme care. Scratches, chemical contamination, or other damage due to
improper cleaning may void the warranty.
•Remove the camera from the optical assembly and bring the camera to a
clean, dry location where it is safe to use flammable solvents (please see
caution below)
•Carefully loosen the lens mount lock ring using the supplied DVC lock
ring wrench.
•Orient the camera so that the lens mount is pointing downward and
carefully unscrew the lens mounting ring and integral filter.
•Place the camera face down on a clean, dry surface to prevent particles
from accumulating on the CCD faceplate.

9
•Once the filter is removed, Use a CLEAN, DRY (preferably brand-new),
camel hair lens cleaning brush (such as those used by photographers) to
gently wipe the particles off of the filter.
•Re-examine the filter after removing the dust. If a smudge is still visible,
proceed by dipping a clean, lint-free cotton swab in ethyl or isopropyl
alcohol. The swab should be saturated, but not dripping.
•Carefully draw the swab once across the surface, then rotate the swab 180
degrees to expose the fresh surface and draw it across the filter surface
again. Be careful not to pool alcohol on the glass surface.
•Re-examine once again and repeat the process once, if necessary.
.
Caution: ethyl and isopropyl alcohols are highly flammable! Do not use near
extreme heat, arcing electrical equipment (such as space heaters) or open
flame! Use only with proper ventilation. Follow all safety instructions
provided by the manufacturer of the alcohol product.
If contamination continues to be a problem, please call DVC Customer Service for
assistance.
3.2.3 Cleaning the intensifier front element (intensified cameras)
The intensifier front element is the glass plate visible when the lens is removed. As
always, dust accumulation can be reduced by minimizing removal of the camera
from the application and replacing the protective lens cap during those periods the
camera is removed.
3.2.3.1 What must I do before cleaning the intensifier front element?
First, remove the lens and carefully examine the front element in a clean location
under mild direct light (care must be taken not to expose the intensifier to strong
light). Try to determine if the contaminants are a few dust particles, oily smudge
(such as fingerprints) or both.
3.2.3.2 What if the contamination is only a few dust particles?
Use a CLEAN, DRY (preferably brand-new), camel hair lens cleaning brush (such
as those used by photographers) to gently wipe the particles off of the surface.
3.2.3.3 What if the contamination includes a smudge?
DVC strongly recommends returning the camera to the factory for professional
cleaning to avoid damage to the camera. Scratches, chemical contamination, or
other damage due to improper cleaning may void the camera warranty.
If contamination continues to be a problem, please call DVC Customer Service for
assistance.
3.2.4 Cleaning the Multispectral Camera optical components (Multispectral Cameras only)
Follow instructions for removal of filters in section 7.10 and clean filters
individually using the instructions for cleaning the infra-red filter in section 3.2.2
above

10
3.3 Infra-red filter removal and installation
The DVC1412A series cameras have very high quantum efficiency in the red and near-
infra-red regions of the spectrum, making them suitable for near-infra-red imaging
applications. In such applications, it may be necessary to remove the infra-red filter. It is
important to note that removal of the IR filter may allow debris to collect on the CCD
faceplate. Please use every precaution to avoid contact with the CCD faceplate and to keep
the camera securely mounted to the optical system or capped when not in use.
3.3.1 How to remove the IR filter
Caution: This procedure will cause the focus calibration to be lost. Readjustment of the lens back
focus will be required after reassembly
1. Loosen the lens mount lock ring with the wrench supplied by DVC
2. Unscrew the lens mount/filter assembly ring from the camera body and remove the lock ring
from the lens mount ring
3. Hold the lens cap with the pins sticking upward in one hand
4. Lower the lens filter assembly on to the pins with the other hand

11
5. Hold the lens cap and rotate the lens ring anti-clockwise and then remove the lens ring.
6. Remove the filter from the filter ring with lens tissue and store in a protective container
7. Replace the lens ring on to the filter ring and screw on clockwise
8. Remove the lens ring from the lens cap

12
9. Screw the lock ring back onto the lens mount ring and screw both back onto the camera. Adjust
focus by loosening the lock ring and rotating the lens mount ring to adjust the lens-to-CCD distance.
To re-install the IR filter or other filters, reverse the above procedure.
