Assignment

High-sensitivity spectroscopy is critical for detecting weak optical signals such as:

• Trace element emission (LIBS)
• Low-concentration Raman scattering
• Weak fluorescence
• Plasma diagnostics at low power
• Environmental monitoring

Conventional spectrometers often use reflective gratings (e.g., Czerny–Turner configuration). While versatile, these systems may suffer from:

• Multiple mirror reflections (losses)
• Alignment sensitivity
• Stray light
• Larger optical footprint

A transmission grating-based spectrometer offers

• Fewer reflective losses
• Compact inline geometry
• High diffraction efficiency
• Potentially improved throughput
• Better mechanical simplicity

This project aims to design and evaluate a transmission grating spectrometer optimized for maximum optical sensitivity.

Objectives

• Design a compact transmission grating spectrometer
• Optimize optical throughput for weak signal detection
• Compare sensitivity against conventional reflective grating systems
• Validate performance experimentally

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
