At B&W Tek, we’ve earned our place as a leader in portable Raman spectroscopy and miniature spectrometers by focusing on what matters: practical, solution-driven systems that deliver quick, accurate answers—no advanced training required. From lab benches to fieldwork, our spectroscopy tools are built for mobility, ease of use, and real-time results.

We specialize in flexible, high-performance spectroscopy systems across UV, Vis, NIR, and Raman. Whether you need a full, ready-to-run Raman system or a modular component setup, our products are built to grow and adapt with your application.

Our Discover-It-Yourself (DIY) systems are ideal for customers who want flexibility and control. Built from a wide range of modular, off-the-shelf components—spectrometers, lasers, sampling accessories, and software—these systems can be easily customized to meet your specific application needs. If you're looking to create a tailored spectroscopy solution without starting from scratch, DIY gives you both freedom and expert support.

With one of the industry’s broadest selections of configurable components—including the smallest TE-cooled CCD array spectrometer available—we support a wide range of techniques like reflectance, transmission, fluorescence, and absolute irradiance, ideal for LED and solar applications.
