Requirements
The SenSys User Manual is divided into six chapters. It is suggested that you
read the entire manual before operating the camera to ensur e proper usage. The
chapters that follow this introduction are
• Hardware Installation — Instructions for connecting the camera to
mount adapters, tripod mounts, and other instruments, as well as for
connecting it to the AIA cable and the power brick
• Configuration Options — Instructions for changing mount adapters,
lenses, and tripod stands
• Component Descriptions — Functional description of each component
• Troubleshooting — Answers to camera hardware problems
• Specifications — Specifications for each camera system component
Note: To install a new camera, begin with the Hardware Installation chapter in this
User Manual and then proceed to the Software Guide.
The SenSys camera system should be operated in a clean, dry environment. The
camera system requires that an easily accessible electrical outlet be available
near the equipment.
The camera system’s ambient operating temperature is 0˚C to 40˚C. The camera
can be operated in any orientation, therefore it can be used on a tripod camera
stand or mounted on a variety of instruments.
Storage
Requirements
Precautions
Store the SenSys camera system in its original containers. To protect the system
from excessive heat, cold, and moisture, store at an ambient temperature
between -20˚C and 60˚C with a relative humidity of 0%–90% noncondensing.
The CCD and other system electronics are extremely sensitive to electrostatic
discharge (ESD). To avoid permanently damaging the system, please observe
the following precautions:
• If you are using high-voltage equipment (such as an arc lamp) with
your camera system, be sure to turn the camera power on last and
power the camera off first .
• Always switch off and unplug the power supply before changing your
system configuration in any way.
• Use caution when triggering high-current switching devices (such as an
arc lamp) near your system. The CCD can be permanently damaged by
transient voltage spikes. If electrically noisy devices are present, an
isolated, conditioned power line or dedicated isolation transformer is
highly recommended.
• Never connect or disconnect any cable while the camera system is
powered on. Reconnecting a charged cable may damage the CCD.
• Never impede airflow through the equipment by obstructing the air
vents.

Component Descriptions
The SenSys camera consists of the camera body and the shutter cover. The
camera body houses the CCD, CCD cooling system, and camera electronics. All
of the components inside the camera body are sensitive electronic components
and are not user accessible. Opening the camera body voids the camera warranty . The
shutter, located behind the shutter cover, is a user-replaceable component.

CCD
MPP Some CCDs have the option of operating in Multi-Pinned Phase (MPP) mode.
When you order a SenSys camera, you choose from a range of CCDs that differ
in size and grade. All SenSys CCDs are scientific-grade, grades with fewer
defects than commercial grades. Scientific-grade CCDs image with better
resolution, have low noise so they can detect weak signals, and are linear over
the dynamic range so you can accurately judge intensity differences between
objects.
MPP CCDs are built to have less thermally generated noise for a given exposure
time, a property useful when trying to detect weak signals.

Metachrome
Certificate of Calibration Each SenSys camera has a Certificate of Calibration. This certificate states the
®
II Metachrome II is a proprietary, optional, permanent CCD coating that is
available on all SenSys CCDs. This coating extends the CCD's sensitivity to
below 200 nm and is transparent from 400 to 1100 nm wavelength light. The
coating requires no maintenance and does not degrade over time.
CCD grade that has been designated by the CCD manufacturer. The certificate
also provides the camera calibration information needed to effectively measure
photon flux with repeatable, scientific accuracy. A copy of the information
contained in the Calibration Certificate is kept on file at Photometrics Customer
Service.
Window
CCD Chamber
The SenSys camera has one window in the optical path. The CCD does not have
a window. Compared to a multiple-window design, a single window reduces
the chance of image degradation due to multiple reflections, stray light, and
interference patterns.
The standard Photometrics window is made of fused silica (quartz) with a
broadband antireflective coating. Fused silica has better ultraviolet
transmission than crown glass. The antireflective coating increases the light
transmitted through the window from 92% to 99%, further decreasing light loss.
Optional infrared-blocking (IR) and sapphire windows are available. The IR
window blocks optical radiation above 650 nm, providing a sharper image. The
sapphire window may be necessary for high-humidity environments.
The window is part of the sealed chamber that protects the CCD from
contamination and excess ambient humidity. Inside the sealed chamber,
packages of desiccant absorb any water vapor.
When the camera is cooled to 10°C, the low-humidity environment prevents
frost from forming on the CCD and condensation from forming on the inside of
the window.
Thermoelectric
Cooler
Shutter
12
SenSys User Manual
Cooled CCD cameras produce less dark current than cameras operating at
ambient temperature. The CCD in the SenSys camera is cooled to 10°C when the
ambient temperature is between 10°C and 40°C.
The CCD is cooled by a single-stage Peltier cooler , a thermoelectric cooler (TEC)
that pulls heat away from the CCD. The heat is rejected into the camera body,
which is cooled by forced air.
The camera has a high-speed, customer-replaceable shutter that maintains a
speed of up to 15 frames per second while still fully opening and closing. The
shutter takes 5 ms to open and 10 ms to close. The camera integration time (the
total time any part of the CCD is exposed) is equal to the shutter open and close
times plus the exposure time.
The shutter is the only mechanical component that has a limited life with heavy
use. Instructions for testing and replacing the shutter are in Chapter 5.
Troubleshooting.
Electronics
The CCD produces an analog signal. The camera electronics convert the analog
signal into a digital signal, data that can be received by the host computer.
Several factors influence what portion of the analog signal translates into digital
data. One factor is the noise in the camera system. The system noise includes the
thermal noise produced by the camera components and the read noise
determined in part by how far the analog signal must travel. The farther an
analog signal has to travel, the more the signal degrades.
To reduce signal degradation, SenSys has low-noise electronics and primary
point digitization (PPD
converter (ADC) as close to the CCD as possible, which reduces the distance the
analog signal must travel.
Another determining factor is the quality of the signal received by the ADC. If
the ADC receives a high-quality signal, the 12-bit ADC digitizes the analog
signal into 12-bit data. With a lesser quality signal, the ADC produces data with
a lower effective bit depth.
The SenSys camera produces an analog signal that uses the full range of the
12-bit ADC (up to 4096 gray levels). Through softwar e, the camera can be set to
High Sensitivity (Gain 3), High Dynamic Range (Gain 2), or High Signal to
Noise Ratio (Gain 1) detection modes. Each gain setting configures the camera
to be responsive to different light-level intensity ranges. The appr opriate range
is dictated by the specific use of the camera.

). The PPD design positions the analog-to-digital
Input/Output
Trigger Port
No matter how fast the data moves from the CCD to the ADC, the camera
readout rate is determined by how quickly the ADC converts the data to digital
form. The SenSys has a 1Mpixel/sec conversion rate.
The SenSys camera has a TTL input/output (I/O) trigger port that is located on
the back of the camera. (See diagram on next page.) When the camera is
shipped, this port is fitted with a black plastic cover.
The I/O port allows you to synchronize the camera trigger signal with external
equipment. Strobes, external shutters, and filter motors are examples of external
triggering devices. The I/O port is a male, D-subminiature 9-pin connector.
Pinout specifications are located in Input/Output Port Pinout on page 29.

Green Light on
Camera Does Not
Illuminate
Green light on camera does not illuminate
Image is fuzzy
Camera does not respond to light
Camera does not focus
Caution: Do not attach or remove any cables while the camera system is powered on.
Allow approximately one minute for the camera to reach operating temperature
and the green light to come on. If the green light does not illuminate, there may
be a problem with the camera's cooling system. Contact Photometrics Customer
Service.

Image is Fuzzy If you have a fuzzy image, and if the green light is off but the camera is hot to
the touch, the CCD's temperature may be too cold. Contact Photometrics
Customer Service.
Camera Does Not
Respond to Light
If your camera has no response to light, a faulty camera shutter may be causing
the problem. To test for a malfunctioning shutter:
1. Turn on the power to the camera.
2. As the camera is powering up:
• If you hear 2 clicks separated by 1 second (shutter opening then
closing), the shutter is working. Call Photometrics Customer Service
for further instructions.
• If you do not hear any clicks, hear 1 click, or more than 2 clicks,
check the voltage between I/O port pins 3 and 9 while you are
powering up the camera. (See Input/Output Port Pinout on page 29.)
If the TTL logic level goes from 0 (low) to 1 (high), stays high for 1
second then drops to 0, the shutter signal is working, but the
shutter is not working. If this happens, you need to replace the
shutter . Follow the procedures in Camera Shutter Needs Replacing on
page 20.
If the TTL logic levels do not indicate a working shutter signal, call
Photometrics Customer Service.

Camera Shutter Needs
Replacing
If your camera's shutter signal is working but the shutter needs to be replaced:
1. Using a 3/32” hex wrench, remove the four #4-40 socket head screws
from the shutter cover.
Caution: Make sure to remove the shutter cover and not the camera back. Removing
the camera back will expose the CCD and void your warranty.

Input/Output Port
Pinout
The input/output port provides information about trigger function and shutter
status. All inputs are pulled up to +5V DC through 10k ohm resistors and
filtered with 2200pf ceramic capacitors. Outputs are driven by a 74F374 latch.
The numbers on the trigger connector diagram below correspond with the
numbers given to the definition of each of the pins. The I/O connector is a
female, D-subminiature 9-pin connector.
Input/Output Port with Pin Numbers
1 SHUTTER OPEN OUTPUT
Active high. A high level on this output indicates that the shutter is
completely open. The output is low when the shutter is closed or in
motion.
2 SHUTTER MOVING OUTPUT
Active high. A high level on this output indicates that the shutter is
opening or closing. The output is low when the shutter is completely open
or completely closed. The length of time this signal is held high is specified
in PVCAM® or by the Shutter Open Delay and Shutter Close Delay
functions in the software.
3 CAMERA EXPOSING OUTPUT
Active high. A high level on this output indicates that the camera is
exposing (integrating). This output does not include shutter open and
close delay times.
4 FLASH
This pin is a TTL-level output that can be controlled through software by
using the FLASH command.
5 FACTORY SETUP
This pin is used for factory setup only and is not to be utilized by the user .
Driving this pin will disable the camera and cause a PVCAM error.
6 FILTERED TRIGGER INPUT
This input uses a TTL voltage level to trigger the camera. The input is
pulled low to initiate a trigger (default). If nothing is connected to the
input, it is pulled high to prevent the system from getting false triggers. To
change the state of this input see TRIGGER INVERT INPUT (8). (The
Chapter 6. Specifications 29
inputs are internally pulled up, therefore it is r ecommended to drive them
with an open collector driver.)
7 TRIGGER INHIBIT INPUT
This input inhibits all trigger signals. If the input is pulled low, trigger
activity is disabled. By default, the input is pulled high so the trigger
circuitry is enabled. (The inputs are internally pulled up, therefore it is
recommended to drive them with an open collector driver.)
8 TRIGGER INVERT INPUT
Active low. A low on this input inverts the state of FILTERED TRIGGER
INPUT (6), causing a high level to cause a trigger. (The inputs are
internally pulled up, therefore it is recommended to drive them with an
open collector driver.)
9 GROUND
System digital ground. Any external circuitry intended to interface with
the trigger control signals must reference this ground connection.
