Stemmer Imaging can now offer fast FPGA-based Camera Link frame grabbers from Silicon Software. The AD4-CL and VD4-CL are part of the popular microEnable IV family of frame grabbers. They are both PCIe x4 Camera Link frame grabbers featuring the new DMA 900 FPGA engine, offering data transfer rates of 900MB/s to the host PC for image acquisition. The boards are ideally suited as an OEM solution for image acquisition. The microEnable IV VD4- CL features an additional FPGA vision processor, which provides powerful and fast image processing completely independent of the host CPU. FPGA designs can be programmed and tested quickly and easily using Silicon Software’s VisualApplets programming environment. VisualApplets eliminates the need for expert FPGA programming and provides extensive and fl exible image processing functionality for software developers plus rapid application development for developers and FPGA engineers.

Framos is now supplying the Strobe Controller (SC) series from Smartek, which provide excellent switching capacities and precision for industrial machine vision applications.
The latest models provide 16A per channel and pulses of down to 1µs. All SC stand out with their time trigger resolution of 1µs and a current pulse resolution of 1mA. This means LED illumination devices last way beyond their standard mode of
operation. Due to ultra-short but high power switching, the illumination intensity can be signifi cantly increased with reduced thermal effects for the LEDs. These strobe controllers come with a feature set of up to six parallel channels, power out for a cooling fan, and comfortable Ethernet access to the controller settings.
The high performance and competitive prices means the devices
are suitable for a growing
list of complex and demanding applications in industry.
Framos is
also distributing Smartek’s Giganetix
camera series. The fully GigE Vision-compliant hardware and driver interface, combined with a compact housing at 35 x 35mm footprint, provides seamless integration in existing cost-sensitive systems. Smartek offers high image quality with minimal noise and a comprehensive feature set
combined with a fi ne selection of four Aptina CMOS and eight Sony CCD image sensors. Excellent trigger latency of ~2µs allows for optimal synchronisation of camera arrays with strobe illumination. Throughout the design of these cameras, utilisation of industrial standards (C-mount, Hirose-plug, RJ45-plug for CAT5e or CAT6 cables) enables a signifi cant reduction of the total costs of the machine vision system.

Both boards support dual independent base, single medium or single full Camera Link cameras and their stable and robust operation offers exceptional price/performance. They also support add-ons such as the CLIO interface, which is used for data redistribution and the Trigger digital IO interface, which enables the integration of peripheral devices such as encoders or lighting. A PixelPlant interface is also available for the VD4-CL to provide extra hardware resources for the more complex image processing tasks. Stemmer Imaging also supplies the Sony FCB E series of colour block cameras with GigE Vision and GenICam functionality. In addition, the CVC GE family includes a Sony FCB E camera equipped with an FGI GigE Vision-compliant interface board produced by Stemmer Imaging and the CVB CameraSuite software development kit. The cameras offer outstanding performance, including true progressive scan from an HAD CCD image sensor. The camera range features zoom lenses from 36x down
to 28x or 18x, combined with 12x digital zoom to bring enhanced versatility. With excellent image stabilisation, white balance, wide D functionalities, motorised iris and a minimum illumination fi gure down to 0.25 lux, these cameras offer exceptional picture clarity in wide- ranging illumination conditions for many applications from security and surveillance to industrial vision. Stemmer Imaging’s FGI interface
board brings all the well-established benefi ts of GigE Vision to this versatile camera range, including the ability to transmit images up to 100m over industry-standard Ethernet cables. Finally, the Stingray camera from
Allied Vision Technologies is now available from Stemmer Imaging, in a version that has no cover glass over the sensor. This is intended for use for special applications such as laser beam profi ling, the use of extended wavelength response coatings or endoscopy, where fi bre optics need to be coupled directly to the sensor itself. The Stingray cameras are modular, offering a wide
selection of lens-mounts, sensors, case variations, interfaces and cable outputs, which can be confi gured fl exibly using building block principles.
For UV imaging in particular, the glass used to cover the sensor can absorb UV rays, inhibiting UV sensitivity. This can affect a number of applications such as semiconductor/wafer inspection, fl uorescence in biology, DNA analysis, astronomy, monitoring of oil spills, monitoring of corona discharge effects in high-voltage electrical transmission lines and imaging of invisible fl ames such as hydrogen and alcohol. A sensor can be made more sensitive in the UV region of the spectrum by coating a UV-sensitive phosphor layer directly onto the surface of the sensor. Sensor performance in the infrared can also be enhanced using specialised IR- sensitive phosphor coatings. In some cases this can offer a cost-effective alternative to the use of specialised IR sensors such as InGaAs.
