Introduction
1.1.
Grasshopper Overview
The Grasshopper digital camera line offers high megapixel resolution and an ultra fast IEEE-
1394b 800Mb/s digital interface. Attractive pricing makes these powerful cameras ideal for OEMs
and system integrators who need compact systems that deliver 1.4M, 2.0M or 5.0M images at
high frame rates. The Grasshopper cameras are particularly effective in demanding imaging
applications such as those used in electronics manufacturing, life sciences and microscopy,
surveillance and security, and ITS.
Users are encouraged to download
detailed information on how to transition applications from the Scorpion to the Grasshopper.
