Piranha2 User’s Manual

• Line rates up to 65kHz

Programmability

• Simple ASCII protocol controls gain, offset, line rates, trigger mode, pixel correction,

test pattern output, and camera diagnostics.

• Serial interface (ASCII, 9600 baud, adjustable to 19200, 57600, 115200), through

Camera Link.

Usability

•  Programmable gains, offsets, and camera controls
•  End-of-line sequence and test pattern output for debugging
•  Single input supply (+12V to +15V)
•  Compliant with CE and MIL-STD-810E (shock and vibration)

Description

Piranha2 takes performance to a new level. Two and four 8 or 10-bit outputs (selectable)
at up to 40MHz deliver up to 160MHz throughput.

Available in 1k to 8k resolutions, Piranha2 is small, light, and uses a single voltage power
supply. Cabling and interface are simplified with the Camera Link high-speed serial
standard. The camera is sensitive, but still provides quiet, uniform output thanks to CDS
(correlated double sampling) and embedded flat-field correction algorithms. Gain and
offset are fully programmable for each output channel, and the camera can output test
patterns for cable/system troubleshooting. All resolutions provide appropriate, readily-
available standard lens options (C-mount, F-mount, and M72x0.75 large format
photography standards).

All these features combine to make Piranha2 the most powerful line scan camera in the
world. Set it loose on your toughest imaging challenge.

Applications

The Piranha2 is ideal for applications requiring high speed, superior image quality, and
high responsivity.

Applications include:

•

Electronics manufacturing inspection

•

Postal/parcel sorting

•

High performance document scanning/image lift

•

Narrow and large web inspection

•

High-end industrial inspection
