Conclusion
The microprocessor-based controller significantly improves the accuracy and flexibility of wavelength scanning in spectrometers.
Supporting Evidence
- The controller allows for bidirectional scanning with improved accuracy.
- Scans using the new controller showed a wavelength shift of no more than 0.03 nm.
- The system can be operated via keyboard or managed by another computer for automated scanning.
Takeaway
This study shows how a computer can help control a machine that measures light, making it more accurate and easier to use.
Methodology
The controller uses an Intel 8085 microprocessor to manage wavelength settings and movements based on user commands.
Limitations
The controller does not compensate for mechanical lag when changing scan direction.
