We envision a future where our advanced optical solutions serve as catalysts for driving innovations that enhance the quality of life and contribute to a thriving, sustainable society. Curious to discover how our products can be implemented in the field? Check out this video! 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 Interested?
