Main Results:

The scanner achieves a dynamic range of 4000 gray levels and a signal/noise ratio of 2000:1.
A step size of 0.1 mm and a step frequency of 2000 steps/second enable high-resolution scanning.
Performance was validated through successful scanning of various test targets and complex biological samples.

Conclusions:

The developed photometric flatbed scanner meets demanding requirements for quantitative analysis.
The instrument provides a robust platform for accurate data acquisition from gels and chromatograms.
This technology enhances the capabilities for detailed analysis in scientific research.
