Piranha HS -8K TDI NIR LIne scan camera

Designed to target solar cell inspection applications where sensitivity in the near-infrared region is critical, this model of the HS TDI line scan family of cameras also provides cost-effective, high- performance solutions for low light imaging with large resolutions and unmatched throughput.

The Piranha HS 8K NIR, 34kHzmodel delivers line rates up to 34 kHz and a throughput up to 320 MPixels/sec. Camera configuration is extremely flexible and the number of Camera Link taps, throughput, and line rate are all software controlled.

These cameras are capable of bidirectionality with up to 256x TDI stages, and prevent overexposure with proven 100x antiblooming. This high sensitivity NIR camera extends Teledyne DALSA’s industry leading high sensitivity product line and provides solutions for imaging in the near-infrared wavelengths from 700 nm to 1050 nm.

Improved sensitivity in near-infrared wavelengths
Typical applications include
• Solar cell inspection
• PCB / Electronics inspection
• Large web applications
• Food and drug inspection

Benefits and key features
• High NIR responsivity
Can displace expensive InGaAs cameras with a silicon based camera
• Line Rate – 34kHz The fast line rate can be utilized because the responsivity is very high. A regular linescan camera would have to be run more slowly in order to have a long enough exposure time.
• High resolution Can displace multiple InGaAs cameras with one Piranha HS NIR camera
• Antiblooming Excellent antiblooming – maintains image quality when parts of the image are overexposed  
• Bi-directional Enables serpentine inspection which reduces system costs
• Flat-field correction Excellent image quality – corrects for any sensor relative issues with respect to fixed pattern noise and pixel response non-uniformity
• Area mode of operation Camera can be quickly aligned to the web by focusing on the web and using the camera in area mode operation (no need for the web to be moving to focus the camera properly)
• NIR response Imaging in the near-infrared wavelengths from 700 nm to 1050 nm

What is TDI technology?
TDI is a method of line scanning which provides dramatically increased responsivity compared to other video scanning methods. It permits much greater scanning speeds in low light, or allows reduced lighting levels (and costs) at conventional speeds. TDI is based on the concept of accumulating multiple exposures of the same (moving) object, effectively increasing the integration time available to collect incident light. As an object moves under each of the 256x lines the charge from that object is added to the previous line so that a total of 256X charges for that object have been accumulated. The object motion must be synchronized with the exposures to ensure a crisp image. Read more
