This manual contains important information and instructions for
the use of the Video Camera VC45 and the Video Module
VM45.

If you work with a Video Camera VC45, you will find all neces­sary information in Chapter 1.
Chapter 2 includes additional information when working with a
Video Module VM45 (= VC45 without housing).

1. Video Camera VC45

1.1 Features of the Camera

The video camera VC45 is a high performance monochrome
camera, based on a solid state image sensor. The high quality
"lens-on-chip" CCD, combined with an advanced electronics, in­creases sensitivity of the VC45 substantially, compared with
high standard video cameras. An absolute black level is
achieved via special darkened reference pixels, yielding a per­fect linear relation between light input and output signal. A great
number of additional features makes the VC45 suitable for
nearly every application.

Video Standard The VC45 is easy to use. The analog video signal is a CCIR,

respect. a RS170 standard signal and compatible to the whole
video equipment on the market.
With a potentiometer at the rear panel of the camera the gain
can be set externally.

Shutter Control An integrated shutter control allows exposure times from 100µs

to 20ms (CCIR) respect. 16.7ms (RS170). It can be set by DIP
switches, parallel or serial input.

Long Exposure A long exposure time can be generated up to 20s by an external

or serial input. When using the external input a special power
down mode prevents the CCD from additional dark current.
There are two integration modes possible: FRAME interlaced
and FIELD interlaced.

The sensor of the VC45 is absolutely insensitive against over­exposure, i. e. too much light cannot damage the CCD sensor.

1.2 CCD Sensor

Overview The following CCD sensors can be used in the camera:

CCIR

format resolution pixel size active sensor

1/2“ 741 x 576 pixel 8.6 x 8.3 µm 6.4 x 4.8 mm
2/3“ 741 x 576 pixel 11.6 x 11.2 µm 8.6 x 6.5 mm

2/3“ 756 x 486 pixel 11.6 x 13.5 µm 8.8 x 6.6 mm

Lens-on-chip Each of the used CCD sensors have the “lens-on-chip“ inte-

grated which increases the sensitivity of about factor 2.
The following drawings show the principle function of the lens-

on-chip technical.

Spectral Response The following drawing shows the spectral response of the used

sensors. Optional the VC45 is available with an infrared cutting
filter. All wavelength higher than about 680nm will be cut off.

= without filter
= with infrared cutting filter

1.3 Connections

Lens Mount The VC45 uses a C-Mount with a standard back focal length of

17.52mm (distance between the front edge of the C-Mount in-

sert and the focal plane of the CCD sensor). The C-Mount has a
fine adjustment to allow for small variations in the focal length of
instruments.
To adjust to a different back focal length, just loosen the set
screw at the bottom of C-Mount front plate. Rotate the C-Mount
insert to the desired position. (The C-Mount insert has a 0.5
thread suitable for fine adjustment.) Then secure the insert
again by tightening the set screw.

Power Supply The power supply (230V), delivered with the VC44, provides

12V (-5%, +10%). At 12V the power consumption is about
300mA. On the power supply a 12-pin special connector is
mounted.

Video Output The analog video output (BNC socket) supplies a standard

video signal (1Vpp, 0.3V Sync-Level on 75Ω) according to CCIR
or RS170 standard.
The video signal is compatible to all video equipment like re­corder, printer, monitors, ...
Please use only 75Ω cables (e.g. RG59)!
Some monitors need an external Sync-signal. In this case you
need a connection between VIDEO OUT of the monitor and
SYNC IN of the monitor.

EXP Long Exposure Control input

TTL level
The exposure time can be prolonged by a low signal.
Typical time range between 40ms ... 10s.

This input is checked at any rising edge of the VSYNC signal (=
end of the VSYNC). When the input is low, the integration time
will be prolonged for the next field/frame.
In the field integration mode multiple of 20ms will be exposed, in
the frame integration mode multiple of 40ms will be exposed.
The input is connected to a pull-up resistance.

DIP switch S1/pin2 = closed; ENB don’t care
or
DIP switch S1/pin2 = open; ENB = low

EXPD Long Exposure Power Down input

TTL level
For long integration times, the sensor can be set in a power­down mode. This mode avoids the generating of an additional
dark current.
This input can be set parallel with the EXP input but must be re­set at least 200ms before the EXP is reset.

The input is connected to a pull-up resistance.

Remark The Long Exposure Power Down can only be active when the

module is in the parallel mode and the shutter is off!

Input to synchronise the camera to an external video device.
A video signal (75Ω) or a TTL signal, consisting of horizontal
and vertical synchronize pulses (composite sync, CSYNC) is
needed. (Internally there is no 75Ω termination.)
The synchronisation is achieved by an internal PLL.

The synchronisation with Genlock can be enabled/disabled by
controlling LSW. This can be done with DIP switch S1:

DIP switch S1/pin 8 = open Genlock disabled
DIP switch S1/pin 8 = closed Genlock enabled

Hint At continuous illumination the brightness of the image is the

same in FIELD or FRAME mode:

CCIR: 40ms with 1 pixel or 20ms with 2 pixels

RS170: 33ms with 1 pixel or 16.5ms with 2 pixels
However, with externally applied shuttering (e.g. flashlight or la­ser pulse), the FIELD mode generated image has double the
brightness of a FRAME mode generated image.

In the FRAME interlace mode the camera produces two fields
generated with a time shift FIELD 1 and FIELD 2 (odd respect.
even lines). These fields are each integrated for 40ms.

The FIELD interlace mode combines 2 lines (1+2, 3+4, ... in
FIELD 1 and 2+3, 4+5, ... in FIELD 2). FIELD 2 is shifted by one
line in respect to FIELD 1 (line shifting).

Long Exposure in Frame Mode

By using the EXP (= exposure) input (pin 3 of the 12-pin socket)
the integration time can be controlled.
In line 10 of the video signal a marker pulse is allocated. If in
this moment the EXP signal is "high", the marker pulse is sup­pressed, the image is not shifted into the shift-register and the
integration time is prolonged.
When operating in the FRAME mode, always 2 x n marker
pulses are suppressed, to achieve two evenly illuminated fields
(40ms). During the integration, black pictures are released from
the camera.

Shutter Mode In the shutter mode, exposure times between 1/50 ... 1/10000 s

can be realized. These shutter times can be achieved by a par­allel and serial programming via external signals (ENB, ED0,
ED1, ED2) or by a parallel setting via internal DIP switches.

The synchronisation is achieved by an internal PPL.
A second possibility is to input separately the horizontal sync
and the vertical sync. In this case the horizontal sync must be
connected to the GENLOCK and the vertical sync must be con­nected to the vertical reset (VR).

The synchronisation with Genlock can be enabled/disabled by
controlling LSW. This can be done with DIP switch S1:

Instructions

Servicing, Maintenance and Cleaning Instructions

The camera is maintenance-free.
Factory settings make any inspection and servicing superfluous.

During use the camera should be protected from hard shocks or
strong vibrations.
Also should the camera be protected from high humidity and
temperature shocks. Avoid exposing to sunlight, since it heats
up the camera housing unnecessarily and prevents the cooling
from reaching its optimum operating temperature.
Keep apertures and slots free to allow air to circulate.

Objective lens or lens adapter should be screwed in gently.
Avoid forcing as it will damage the tread.

Use a soft and dry cloth to clean the housing.

Cleaning Method for the Optical Part

In principle every cleaning method bears the danger of damag­ing an optical surface.
Therefore clean only if it is strictly necessary.

As a first step use dry air to blow out dust particles. Avoid strictly
to wipe on a dry glass surface.
In case dirt cannot be removed by blowing, use special optical
cleaning fluids. Adequate fluids for optical surfaces are: pure
dehydrogenated alcohol, pure acetone or cleaning fluids avail­able in photo shops. Use a soaked cotton tip and take care to
wipe only on glass surfaces, avoiding contact to metal surfaces,
e.g. C-Mount thread, otherwise microscopic dirt and metallic
chips are released, causing irreparable scratches on the glass
surface.

Never use aggressive cleaning substances, e.g. benzine, spirit,
nitro solvents, etc. commonly found in labs. Such substances
may destroy or damage the surface on which they are applied.
The best is to avoid any dirt on optical parts, e.g. by replacing
immediately the black protection cap when removing the objec­tive lens. Do not leave the camera’s optical input window open,
without lens or protecting cap.

Our warranty does not cover damaged optical surfaces caused
by improper cleaning methods.
