Functional Principle 

The confocal CSU-X1 spinning disc unit scans 
hundreds of image points simultaneously. 
Compared to conventional spot scanners, distinctly 
higher image rates can thus be achieved. For 
detection of fluorescence, EM CCD cameras of 
high quantum efficiency can be used, which 
reduces the level of illumination intensity and 
phototoxicity to a required minimum. 

A CSU-X1 confocal scanner includes a so-called 
Nipkow rotating disc with thousands of pinholes 
arranged in a spiral-like pattern. By illumination 
and through-disc detection, just as many image 
points can be imaged concurrently. Because the 
disc rotates, the sample surface is completely 
scanned a bit at a time. After rotation of 30°, the 
entire visual field of the camera has been fully 
imaged once. 

Since a large amount of incident light would be 
blocked by the areas between the pinholes, the 
scanning disc unit is equipped with a special 
tandem disc setup. The Nipkow disc acts in unison 
with a preceding second mechanically coupled 
disc. It contains micro lenses to exactly focus and direct the incident bundle of excitation light through 
the subsequent pinholes for increased light efficiency. 

For optimal adaptation to the various operating requirements, the CSU-X1 scanning disc unit is available 
at different configuration levels. 

Spin speed: 

 

Depending on the dynamics of an application, the Nipkow disc’s spin speed may vary. Available options 
are: 

 

a fixed rotation speed of 1800 rpm, 

 

variable speed settings from 1500 to 5000 rpm 

Filter wheels:   
Fast optional filter wheels reduce emission filter switch times to as little as 33 ms (purely mechanical 
switching time) between neighbouring positions. Combined with AOTF-based selection of a desired 
excitation wavelength, this facilitates express multi-channel experiments. 

Dual camera operation: 

 

The dual camera option provides two cameras for concurrent image acquisition in two different emission 
ranges. This prevents a time offset between a pair of channels and helps avoid inaccuracies during co-
localization or ratio calculation tasks.
