CHAPTER 1

INTRODUCTION

The QImaging Retiga EXi CCD digital camera features enhanced visible and IR quantum efficiency for super high 
sensitivity for demanding low light and fluorescence imaging applications. A progressive scan interline CCD 
sensor gives a resolution of 1.4 million pixels in a 12-bit digital output. High-speed low-noise electronics provide 
linear digital data for rapid image capture. The 

FireWire

 IEEE1394 digital interface allows ease of use and 

installation with a single wire requiring no framegrabber or external power supply. The Retiga EX

i

 includes 

QCapture Software for 

Windows

 and Mac

(R)

 based software systems for real time image preview and capture. 

A Software Development Kit (SDK) is available for interfacing with custom software.

Power Requirements

The Retiga EXi Fast 1394 can be powered through a single IEEE 1394 (FireWire) cable.

Power:

 

Cooled Retiga EXi Fast 1394 = 11 watts

Uncooled Retiga EXi Fast 1394 = 6 watts

Input voltage range:

 8 - 24 volts

Host Requirements

For Windows PCs:

Pentium

 CPU, running at 300MHz.

256 MB RAM.

Video card with 8 MB video memory capable of 32-bit color output.

Microsoft Windows 98 Second Edition, Windows Millennium Edition (ME), Windows 2000, 
or Windows XP Professional.

If the PC is not equipped with a FireWire card, the supplied card must be installed.
