Custom Automatic positioning platform for spectroscopy
SojaLab develops custom automation and positioning systems for scientific, spectroscopic, and radiation detection applications.
The system was developed in close collaboration with the Czech Metrology Institute to meet the demanding requirements of advanced radiation measurement and spectroscopy applications.
For a specialized radiation measurement project, we designed and manufactured a remotely controlled positioning platform for:
- collimator alignment,
- spectroscopic detector positioning,
- ionizing radiation source targeting,
The platform was optimized using low-scattering materials such as PLA, PET, and carbon fiber composites (excluding essential drive components and colimation)
to reduce interference with radiation measurements and improve detection accuracy.
The solution provides:
- Remote-controlled positioning platform,
- Precision alignment of collimators and spectroscopic detectors
- Stable detector alignment
- Lightweight composite construction
- Compatibility with Hofmeister collimator kit
- Pixel detector-based alignment systems
- Compatibility with various detectors, available customisation to user needs
- Integration into advanced spectroscopy and radiation detection environments

Hofmeister colimator kit
The collimator kit is designed for applications involving high X-ray intensities that exceed the operating limits of the detector and signal processing electronics. It enables precise collimation of the primary X-ray beam, thereby contributing to stable measurements, higher data quality and reliable protection of sensitive components even under demanding operating conditions. By selecting appropriate tungsten collimation discs, it is possible to control the intensity of the incident X-ray radiation and thus ensure optimal processing of the X-ray spectrum by the detector and electronics.

Comprehensive solutions – fully customizable to meet customer needs
- Complete collimator housing assembly
- Collimator shielding
- Tungsten collimation discs (with apertures ranging from 25 μm to 1 mm diameter, thickness from 1 to 2 mm)
The comprehensive nature of the solution offers users maximum flexibility and allows the system to be easily adapted to a wide range of applications – from laboratory research to industrial measurement.
