Instrument Components

The main components of the GenePix

®

 4000B Microarray Scanner are 

described below.

Protective enclosure

The protective enclosure protects the user from exposure to laser 

radiation, high voltage, and moving parts.

Optics

The GenePix 4000B Microarray Scanner uses a laser-excitation based 

fluorescence scanning and imaging system. The optical system consists 

of excitation light, mirrors, lenses, filters, and photo-detection. 

Lasers

In the GenePix 4000B Microarray Scanner, laser excitation is provided 

by individual 532 nm and 635 nm lasers. These wavelengths 

correspond to the ideal wavelengths used to excite the fluorophores 

Cy3 and Cy5 (GE Healthcare), or other fluorophores with similar 

fluorescent characteristics. The individual lasers have been selected 

because of their superior optical performance and reliability. Since the 

performance of such lasers is often sensitive to external temperature 

fluctuations, the scanner uses an active temperature stabilization 

design to minimize temperature-based laser fluctuations. The GenePix 

4000B Microarray Scanner automatically corrects fluorescent intensity 

for normal variations on a pixel-by-pixel basis.
With the GenePix 4000B Microarray Scanner, laser power can be set to 

100%, 33%, or 10% of the total laser output. This feature can be used 

when the fluorescence of the sample is too bright, or when 

photobleaching is a problem.

WARNING!  Laser Hazard! Do not remove the protective 

enclosure. Operating the scanner with the protective enclosure 

removed exposes the user to laser radiation.
