Imaging Telecom Imaging Product Line LD3500 Series Low-Cost Digital Linescan Camera 512, 1024 and 2048 Pixels, and Parallel LVDS Outputs P R E L I M I N A R Y Lighting D A T A S H E E T Description In the LD3500-series digital linescan camera, PerkinElmer has combined the best features of photodiode array detection, high-speed charge-coupled scanning, and digital line scan camera technology to offer an uncompromising solution to the increasing demands of advanced imaging applications. The LD3500-series are high performance, low-cost, digital linescan cameras. The LD3500 features a CameraLink™ or Parallel LVDS (RS-644) style video output with resolutions of 512, 1024 or 2048 pixels, which can achieve data rates of up to 20 or 40 MHz with exceptional noise immunity. The cameras are designed for volume applications where small size and low cost are required. In order to allow the user to compensate for variations in illumination found in "real-world" application environments, the cameras feature adjustable gain levels. The LD3500-series cameras feature a geometrically precise photodiode CCD image sensor with 14µm photo-elements. State of the art electronic design enables the LD3500-series to deliver consistent, reliable performance while the sturdy metal housing provides maximum protection in a variety of harsh environment and factory floor conditions. The LD3500-series linescan cameras transform light imaged during a scene into a digital video signal. Antiblooming structures within the sensor ensure superior performance over a wide range of lighting conditions. User-defined control is possible for line rate, integration time and video data rate. Features • 20 and 40 MHz output rate models • Geometrically precise 14 µm square pixel linear CCD • Small size: 2.5" H x 2.5" W x 3.2" L • High dynamic range (250:1) • CameraLink and Parallel LVDS video output models • 8-bit grey scale resolution • Antiblooming control • Single power supply operation • Electronic exposure control • Adjustable gain levels • CE mark certified • Line scan rates to 68 kHz The LD3500 cameras may be interfaced to most frame grabber cards, allowing for a tested, plug and play solution.

When the camera is set to Master Mode, the camera operates at its maximum line scan and data rate. When the camera is set to Slave Mode, the cameras scan and data rates are determined by the users input signals to the camera. The opertaing mode is set via the serial connection on the CameraLink models, and is autodetected on the LVDS models. Autodetection is accomplished by looking for either a Line Transfer (LT) and/or External Clock signal. If the camera receives a LT signal, but no external clock, it will continue to run a the maximum data rate, but will only intiate a LT upon signal. If the camera recieves an external clock signal, it will run at that clock signal with either an internal or external LT signal. Input/Output Signal Specifications The LD3500 camera requires a single DC supply (+12 to 24V) for operation. An internal oscillator sets the default data output rate to default model rate (20 or 40 MHz). CameraLink Models: CameraLink allows for 4 manufacturer-defined camera control signals (CC1-CC4). CC1 is a Line Transfer (LT) signal. CC2 is a Line Reset (LR) signal. CC3 and CC4 are reserved for future assignment.

The readout registers, in turn, transport the charge from each photosite in succession to the video outputs. The exposure time of the camera can be externally controlled using the LR input. The LR input is active low (ON) in polarity and therefore, when not in use, must be held high or left unattended (OFF). In this condition, the exposure time is defined by the period of the LT signal. Output signals are compliant with CameraLink specifications. Parallel LVDS (RS-644) Models: Parallel LVDS models of the LD3500 provide Master Clock (MCLK), Line Transfer (LT) and Line Reset (LR) input signals. The MCLK input determines the data rate frequency for values up to maximum clock of the camera. The MCLK input is optional, as the camera is preset to run off of the internal oscillator at the default maximum data rate. Should a data rate slower than that default rate be necessary, an externally supplied master clock can be used. The data rate may be run from 2 MHz to cameras maximum clock rate. The Line Transfer input signal transfers the charge from each photosite to the readout registers. The readout registers, in turn, transport the charge from each photosite in succession to the video outputs. The exposure time of a LD3500-series camera can be controlled by using the external LR input. The LR input is active low (ON) in polarity and therefore, when not in use, must be held high or left unattended (OFF). In this condition, the exposure time is defined by the period of the LT signal. When using the LR input signal, the exposure period is defined to be the time between the rising edge of LT to the rising edge of LR. The LD3500-series camera provides two output synchronization signals: Camera Clock (CCLK) and Line www.perkinelmer.com/opto PDP-206.01B - 7/2002W Page 2 Digital Linescan Camera Input/Output Signal Specifications (Continued) Figure 2. Connector Diagram Enable (LEN). The Camera Clock (CCLK) operates at either the MCLK frequency or default camera frequency, and is synchronized to the analog video. The output of the CCLK signal can be used to capture digital video data by a frame grabber or digitizer. The Line Enable (LEN) signal brackets the valid digital video. The signal becomes high one CCLK period before the first valid pixel and goes low one CCLK period before the last valid pixel. In all modes of operation on the LVDS models, a single line delay is present due to the necessity of storing all video data into memory before the video is output.

Power Connector Pinout Gain levels are set by differential RS-644 gain control inputs on the camera connector. The gain levels can be set at 1, 2, 4 and 8X full-scale gain, allowing the user to easily configure the camera output to suit their application needs. Gain settings are not held after power down; proper input signals must be given at start-up, and held throughout operation for gain settings to remain at desired levels.

The sensor is mounted on an aluminum plate that efficiently transfers heat to the camera case. The camera is provided with a standard 1/4"-20 UNC tripod mounting block, which can be attached to any of the four sides of the camera. The mounting holes used to attach the tripod block can also be used to mount the camera assembly. Additionally, the CCD sensor is thermally coupled to the faceplate of the camera, and the conductive cooling of this surface is useful in minimizing thermally generated dark current and noise of the camera system. Optical Interface The LD3500-series cameras are equipped with a U-Mount lens interface (MA2-16H) that is aligned to the CCD sensor. These standard adapters allow the user to select the optimum lens to suit their particular application. 13 Inner Shield Table 1b.
