Assignment

Single-beam spectrometers measure signal intensity from one optical path. However, they are sensitive to:

• Source intensity fluctuations
• Plasma instability (LIBS)
• Laser power drift
• Detector sensitivity changes
• Environmental variations

A dual-beam spectrometer introduces a reference channel alongside the sample channel, enabling:

• Real-time intensity normalization
• Improved quantitative stability
• Drift compensation
• Higher signal reproducibility
• Reduced noise from source fluctuations

Dual-beam systems are widely used in absorption spectroscopy but are less common in emission spectroscopy or LIBS setups. Evaluating the feasibility and performance benefits in advanced spectroscopy systems is therefore of strong technical interest.

Objectives

• Investigate different dual-beam spectrometer architectures
• Evaluate technical feasibility for laboratory or industrial integration
• Design a conceptual prototype
• Assess performance improvements compared to single-beam systems

We are looking for

We are looking for an enthusiastic HBO or WO student with a background in:

• Applied Physics
• Mechanical Engineering

We offer

• A good compensation per month
• Travel reimbursement of €0,23 per km (when traveling by car)
• Informal work atmosphere, short lines of communication
• Working in a high-tech environment
