Area-scan cameras see color

Click here to enlarge image

Expanded A400 series cameras are now all in a color version. The CMOS sensor-based cameras produce up to 96 frames/s at full 2352 × 1726-pixel resolution; higher frame rates are possible when the area-of-interest (AOI) feature is used. These cameras offer better differentiation of image nuances than can be achieved with a monochrome camera. A programmable AOI and exposure time sequencer let the user program an automated sequence of changes in the camera’s AOI and exposure time settings without using the serial communications port. Using the sequencer results in shorter inspection cycle times.

High-illumination lighting is stable

Click here to enlarge image

MG Wave high-power coaxial spot LED lights provide stable, high illumination for machine-vision applications requiring optimal lighting conditions. Designed to be compatible with machine microlenses, the small, lightweight MCEP Series lamps utilize proprietary collector optics and lightguides for maximum illumination. Stable illumination is ensured through use of a choice of dedicated single-channel or three-channel constant-current power sources. Two fiberoptic guide-connection options can be used with the high-power spot LEDs: the single-lamp type guide (MCEP-ADLG) and a three-lamp guide (MCEP-AD3LGB).

IMS-LM series linear stages are designed for self-supporting applications with travel ranges from 300 to 600 mm. They are solutions for precision industrial applications such as semiconductor wafer inspection, microelectronics test and assembly, pick and place, DNA sequencing, or laser machining. The IMS-LM series utilizes a FEM optimized aluminum extruded body that is extremely stiff, while minimizing the bending effect caused by different thermal-expansion coefficients of the aluminum body and the steel rails. Unlike screw-driven stages, the IMS-LM has a center-driven linear motor as the driving element that is noise-free and has high speed, acceleration, and system responsiveness with no wear of motor brushes or drive screws. The stages are more than 100 mm shorter than comparable screw-driven stages.

Cameras use compression

JPEG compression IP core, the CTJPEG-04 for FPGA-based intelligent cameras, can sustain 500 frames/s at a resolution of 1280 × 1024 pixels. The compression engine was customized from the CCI IP core library to fit FastVision FastCamera13 and FastCamera40. Based on the JPEG ISO/IEC IS 110918-1 standard image-compression algorithm, the design supports a continuous data flow and can be used in stringent video-compression applications without the support of a host or a coprocessor. This enables images captured to be compressed through a configurable user interface and to be transmitted to a host via a USB 2.0 standard interface. The core is fully synchronous and autonomous and offers localized image degradation when the high-frequency content in the processed images is too high.
