1. 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 7 1 2 Cleaning the infra red filter if included The DVC 16000 is available with an infra red filter within the F mount which is visible when the lens is removed This filter blocks invisible near infra red light from reaching the CCD sensor This is desirable in most applications where the camera is imaging in the visible spectrum 7 1 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 7 1 2 2 What 1f the contamination is only a few dust particles 11 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 7 1 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 void2. into two halves which are read simultaneously This approximately doubles the frame rate of single channel readout at a given frequency The DVC 16000 has five basic operating modes described in detail below Each mode can be operated at either 20 or 40 MHz and can support binning and region of interest All operational modes are initiated by a trigger signal In the case of continuous modes the trigger initiates the stream and the camera continues to run in streaming mode until explicitly disabled The edge triggered single frame mode produces one exposure in response to the leading default falling edge of the trigger signal Finally in bulb mode the camera exposes for the duration of the trigger pulse beginning on the leading default falling edge and ending on the trailing edge Readout occurs immediately after the trailing edge The trigger signal can have three different sources the external TTL trigger via the auxiliary connector see appendix B the software controlled trigger via a hard wired Camera Link camera control line or the software controlled through camera trigger command via the Camera Link serial port Developers should consult the DVC Camera API documentation for further information on the software controlled triggers If the TTL external trigger is used the trigger signal must be active low The trigger point is the high to low leading edge of the trigger signal 5 1 Operating speed and single dual

4. port option The DVC 16000 is capable of operating at pixel rates of 20MHz and 40MHz and with single or dual port options as described above All camera functions e g exposure mode binning ROI etc are operational at either speed subject to the limitations below 5 1 1 20 MHz operation 20MHz operation gives the user the maximum dynamic range minimum noise floor and lowest power operation Dynamic range refers to the maximum signal swing under which the camera meets performance specifications and it is expressed in the maximum number of captured electrons on the CCD At 20MHz the DVC 16000 is capable of approximately 30 000 electrons dynamic range 5 1 2 40 MHz operation 40MHz operating speed provides the user with the highest capture frame rates at the expense of slightly higher noise and power dissipation Because of amplifier limitations on the KAI 16000 CCD the DVC 16000 is capable of approximately 20 000 electrons dynamic range at 40 MHz 5 1 3 Single port and dual port options 5 2 The DVC 16000 is capable of readout via a single port all 16 million pixels read out through a single 12 bit channel or dual port in which the image is split down the middle in the slow scan direction and each half is read out simultaneously using two 12 bit channels The port options are available in both 20 MHz and 40 MHz and for all operational modes Dual port operation can result in slight signal mismatch between the two im
5. the warranty e 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 e 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 e 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 e 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 e Re examine once again and repeat the process once if necessary If contamination continues to be a problem please call DVC Customer Service for assistance 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 7 1 3 Infra red filter removal and installation If greater near infra red sensitivity is desired the infra red filter can be removed It is important to note that removal of the IR filter can allow debris to collect on the CCD faceplate Please contact the factory
6. CCDs exhibit very low smear levels and smear should not be noticeable under normal operating conditions 10 7 Maintenance 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 will void the camera warranty DVC professional cameras are manufactured in a clean environment Before shipping each camera is tested to assure that it meets stringent specifications for cleanliness and quality 7 1 Cleaning Guidelines Frequent lens changes especially without careful attention to contaminants can allow debris to accumulate on the infra red blocking filter CCD and lens surfaces Therefore DVC Company provides the following guidelines for maintenance of these components To minimize the need to clean the optical surfaces do not remove the protective lens mount cap shipped with the DVC 16000 camera until you are ready to mount the camera to the optical system CAUTION Extreme care should be taken to avoid exposing the CCD faceplate unless absolutely necessary Fingerprints or other evidence of contact with the CCD faceplate may void the warranty 7 1 1 Cleaning the lens or optical assembly Please follow the lens manufacturer s recommendations for cleaning DVC Company is not responsible for any damage caused to a lens or optical assembly caused by customer cleaning or misuse To ensure optimum image quality with any
