Thunder Optics – From Laboratory Experience to Real-World Spectroscopy

Thunder Optics is a French company based in Montpellier, a major hub for science and innovation in Europe. Founded in 2017, the company designs and develops spectroscopy instruments for research, industry, education, and applied fields such as gemology.

Today, Thunder Optics products are used in more than 83 countries, including by leading institutions such as NASA, Cambridge University, and Yale University.

A Scientific Approach to Instrument Design

Thunder Optics was built on a simple idea:

Advanced scientific instrumentation should not be limited to large institutions with unlimited budgets.

Founded by an experimental astrophysicist and former university professor, the company develops instruments based on real laboratory experience — not just theoretical specifications.

Every system reflects decades of hands-on experimental work in real laboratory environments.

Every system is designed with a focus on:

• real experimental constraints
• usability
• performance
• adaptability

What Makes Thunder Optics Different

Most spectroscopic systems are designed as fixed, closed solutions.

Thunder Optics follows a different approach:

Designed by a scientist with 25+ years of experimental experience

All systems are developed by someone with over 25 years of experience in experimental physics and international research environments.

Fully modular systems designed for real experimental constraints

Our instruments are not “off-the-shelf”.

They are designed to adapt to real applications, including:

• configurable cosine correctors with adjustable thickness
• flexible connection options (fiber or direct coupling)
• modular optical configurations

Compatibility with standard ecosystems

Our components integrate seamlessly with widely used optical systems, including Thorlabs-compatible components.

Performance-driven design

Our Raman probes and systems are optimized for real-world performance, focusing on signal quality, robustness, and usability.

Research, Consulting and Custom Solutions

Research and innovation are at the core of Thunder Optics.

We provide:

• scientific consulting
• application-specific support
• development of tailored solutions

Our goal is not only to provide instruments, but to help users fully exploit their capabilities.

The Founder — Dr. Amayas T. Mostefaoui

Dr. Amayas Toufik Mostefaoui is a Doctor of Experimental Astrophysics and former professor of experimental physics, with over 25 years of experience.

He has worked in leading institutions worldwide, including:
Cornell, UC Berkeley, Université de Rennes 1, Chemnitz University, University of Milan, Synchrotron SOLEIL, and University of Bejaia.

From building telescopes to building instruments

At the age of 9, unable to afford a telescope, he built his own.

That same mindset — building, experimenting, optimizing — led to the creation of Thunder Optics.

From First Prototypes to Global Impact

Thunder Optics launched in 2017 with:

• a USB mini spectrometer
• a basic Raman probe

Since then, the company has continuously improved its systems, increasing performance while maintaining accessibility.

Key Innovations

SMA Spectrometer (2018)

Up to 120× higher sensitivity than early designs, with strong cost-efficiency.

Accessible High-Performance Raman System

A system designed to make Raman spectroscopy more accessible without compromising performance.

Collaboration with NASA

In 2019, Thunder Optics was selected by NASA Goddard Space Flight Center for high-performance Raman instrumentationr.

This led to advanced systems such as:

• Affa Raman Spectrometer
• Gurzil Raman Microscope

Innovation: ISIM Microscope Raman Probe (Patent Pending)

Thunder Optics continues to innovate with the development of the ISIM Microscope Raman Probe, currently patent pending.

This system is a unique development reflecting Thunder Optics’ advanced expertise in Raman spectroscopy, it offers:

• enhanced optical efficiency
• improved signal collection
• optimized integration with microscopy systems

It is designed for demanding applications requiring high precision and adaptability.

Recognized Expertise in Spectroscopy

Thunder Optics has built an international reputation through:

• collaborations with research institutions
• use in more than 83 countries
• adoption by leading organizations such as NASA

Its expertise is based on decades of hands-on experimental work.

A Global Company With a Human Approach

Thunder Optics operates at the intersection of:

• research
• industry
• education

Its instruments are used by researchers, engineers, educators, and advanced users worldwide.

Our Mission

Science and Knowledge for All without compremise on performance

We believe that scientific instrumentation should be:

• accessible
• adaptable
• and designed for real-world use
