Basic functions 

The SVM340 combines an inverted fluorescence video microscope with a programmable 
synchronizer and software for on-line image acquisition, processing and storage. With the 
uScope application, you can directly store the video data on computer disk as .avi files and 
perform advanced real-time video processing.  

1.3

 

Computer requirements 

The uScope software is designed to stream digitized video sequences directly to disk, so it is 
recommended that the computer fulfills the following minimum requirements: 

 

Windows 7 or newer 

 

RS232 port for communication, or USB port and a RS232-USB adapter 

 

minimum of 1 GB of RAM (4-8 GB recommended) 

 

80 GB hard disk (500-1000 GB recommended). 

 

USB Port for DP1 or DP5 Optics Module:  

-

 

USB2.0 (or USB3.0) port for DP1 Optics Modules (A-DP1-BW, A-DP1-C) 

-

 

USB3.0 port required for DP5 Optics Modules (A-DP5-BW, A-DP5-C, A-DP5-EPI)  

Many PC video input devices include on-board image compression hardware, converting the 
video stream into various compressed video formats. Image compression standards like MPEG 
are designed for general visual imagery and may not be suitable for all types of imagery 
occurring in microfluidics device diagnostics, e.g., the images of isolated small particles as 
recorded in Particle Image Velocimetry (PIV) experiments. The ability to record uncompressed
