New 16k high dynamic range line scan camera
21 Apr 2016
Used in a variety of applications, including the detection of small defects at high speeds and over a large field of view in LCD and OLED flat panel displays, printed circuit boards, film and large format web materials, the Piranha XL XDR offers true exposure control. Applications where the product speed may vary lead to under or over exposure when exposure times are fixed. Exposure control, however, provides more precise control and consistent exposure however much the speed may vary. Exposure control also allows different exposures on different lines for extended dynamic range.
The Piranha XL XDR offers a 125 kHz maximum line rate at 16k pixel resolution, combining high sensitivity with very low noise through Time Delay Integration (TDI) on-chip summing of 8 or 12 image lines. This delivers extremely high image quality for high-speed applications. The high speed and high resolution brings faster throughput and can also lower system cost since fewer cameras may be needed for any given application. The choice of 8 or 12 rows provides the flexibility to meet a larger number of inspection needs. The improved signal-to-noise ratio ensures better detection of smaller defects in various lighting conditions. The camera’s high responsivity (up to 1,200 DN/njcm2 in 12 bit at 1x gain) gives increased sensitivity in low light conditions thus reducing lighting costs.
The new camera features the field-proven industry-standard CLHS interface for very high speed data transfer over long transmission distances with flexible cabling. This, combined with the Piranha XL XDR’s built-in Trigger to Image Reliability (T2IR) framework, safeguards every bit in the camera’s full 2.0 GB/s data throughput. T2IR provides monitoring, diagnostics, track and trace, and buffers to further improve reliability, which in turn delivers more uptime, more productivity, and lower costs. The T2IR framework also extends across the combination when the camera is paired with Teledyne DALSA’s Xtium CameraLink HS frame grabber.
Teledyne DALSA is one of the largest companies serving the machine vision industry and is unique in that it is vertically integrated; from sensor design and manufacture, through image capture and processing, to software for imaging optimisations and analysis.
