Warranty Seller warrants that the article to be delivered under this order will be free from defects in
material and workmanship under normal use and service for a period of one year from date of
shipment. The liability of Seller under this warranty is limited solely to replacing or repairing
or issuing credit (at the discretion of Seller) for such products that become defective during
the warranty period. In order to permit Seller to properly administer this warranty, Buyer
shall:
(1) Notify Seller promptly in writing of any claims;
(2) Not open the camera cover as there are no user serviceable parts inside.
(2) Provide Seller with an opportunity to inspect and test the products
claimed to be defective. Such inspection may be on customer's
premises or Seller may request return of such products at customer's
expense. Such expense will subsequently be reimbursed to customer if
the product is found to be defective; and
(3) Shall not return any product without prior return authorization from
Seller.
If a returned product is found to be out of warranty or found to be within the applicable
specification, Buyer shall pay an evaluation and handling charge, in addition to possible repair
and/or replacement costs. Seller will notify Buyer of the amount of said evaluation and
handling charges at the time the return authorization is issued. Seller will inform Buyer of
related repair and/or replacement costs and request authorization before incurring such costs.
Buyer shall identify all returned material with Seller's invoice number, under which material
has been received. If more than one invoice applies, material shall be clearly segregated and
identified by applicable invoice numbers. Adjustment is contingent upon Seller's examination
of product, disclosing that apparent defects have not been caused by Buyer's misuse, abuse,
improper installation or application, repair, alteration, accident or negligence in use, storage,
transportation or handling. In no event shall Seller be liable to Buyer for loss of profits, loss or
use, or damages of any kind based upon a claim for breach of warranty.

1Introduction
1.1 What’s In this Manual
This manual describes the receiving, unpacking and inspection of your LD3500
series camera. Included is a operational overview that defines the camera
operation and the controls provided. Guidance is provided for the installation,
setup and initial operation of your LD3500 camera.
1.2 Purpose
To provide machine vision system engineers and technicians a definitive guide
for integrating LD3500 series cameras into their specific machine vision
application.
1.3 Product Overview
The LD3500 series cameras are designed for linear line scan image capture
applications. 512, 1024 and 2048 pixel line scan image capture is offered at 20 or
40 megapixels/second, depending on the camera model selected. Each camera
uses a PerkinElmer P-series photodiode linear array with 14µm pixel pitch at a 14
µm aperture. This provides a 48dB dynamic range over a spectral range of 350 to
1000 nm. All camera control functions are selected by the serial connection on
the Camera Linkmodel or automatically detected on the LVDS model. Digital
I/O is provided as differential RS-644 for all camera models.
1.4 Functional Description
The LD3500 series cameras incorporate high performance, high resolution line
scan image sensors. (PerkinElmer Optoelectronics Imaging Systems parts
RL0512PAG, RL1024PAG, or RL2048PAG) featuring pinned photodiode pixels.
Each photodiode converts incident light into discrete charge packets that are
converted to an analog voltage.
The analog voltage is processed as a single channel sampled and held raster order
analog video data signal. Analog processing circuitry provides adjustable gain
levels allowing the accommodation of unique lighting requirements. Figure 1 is a
block diagram illustrating the major camera components.

3Receiving and Inspecting Your Camera
3.1 Unpacking Your Camera
Inspect the received shipping container for any damage. If a shipping container
shows visible signs of damage, it should be retained until all of the contents have
been checked for completeness and absence of damage. Unpack the received
shipping container and account for each item listed on the accompanying packing
list. Visually inspect each item for absence of damage. In the event of damage,
notify the shipper and the PerkinElmer shipping department. Retain all shipping
materials for shipper inspection.
Your first LD3500 shipping container in accordance with the enclosed packing
list should contain the following:
1. LD3500 camera in static resistant envelope with unbroken seal.
2. Users Manual
3.2 Customer Supplied Components
The following components, not supplied with the camera, are required for
installation and operation of the camera in your particular machine vision
environment.
1. Camera Lens + Extender (Available by contacting PerkinElmer)
2. Camera mounting hardware
3. PC with Frame Grabber and digital I/O
4. Power Supply
5. Interface Cable (Available by contacting PerkinElmer)
6. Web illumination source
7. Web speed and light control.
This is not a complete list of items that may be required for your specific
application, but represents a minimum required to verify camera operation.
Note: The majority of the customer supplied items are peculiar to each installation and
may require custom fabrication. Guidelines for fabrication are provided in
Appendix A.
