Label-free imaging with highest contrast
Label-free, multicolor imaging by detecting intrinsic molecular vibrations, revealing lipid metabolism, protein synthesis, and drug dynamics in real time without photobleaching.
SRS imaging solutions
Label-free, multicolor imaging by detecting intrinsic molecular vibrations, revealing lipid metabolism, protein synthesis, and drug dynamics in real time without photobleaching.
Every molecule vibrates in a unique way, creating an optical fingerprint that reveals its chemical identity. Raman microscopy detects these vibrations to visualize the molecular composition of cells and tissues directly, without stains or labels.
Coherent Raman imaging, including SRS and CARS, enhances the signal by several orders of magnitude and enables imaging speeds fast enough to capture biological dynamics in real time.
Benefits
Experience imaging that reveals true molecular detail – fast, clean, and unrestricted by traditional markers.
Dye-free imaging of living cells and fresh tissue, preserving the native biological state.
Captures chemically specific information, enabling data-rich analysis beyond morphology.
Subcellular resolution revealing fine structural and molecular details.
Enables real-time observation of living cells and dynamic biological processes without causing damage.
Molecular depth
Reveal subtle chemical patterns, material signatures, and physiological processes instantly – delivering deeper understanding without adding steps or dyes.
Each SRS pixel contains a full molecular spectrum that reveals local chemical composition. These vibrational signatures from lipids, proteins, and nucleic acids provide chemical contrast beyond structure alone. Capturing spectra across the sample enables label-free biochemical imaging. With high tuning speed and a compact design, Refined Laser Systems records these molecular fingerprints rapidly and reliably, making advanced SRS imaging practical for real biological research.
SRS reveals cellular and tissue processes that remain invisible to fluorescence microscopy. It highlights lipid droplets, membranes, and cytoplasmic regions based on their natural molecular composition. This chemical contrast allows to study metabolism and membrane organization under physiological conditions.
The multiphoton nature of SRS enables imaging deep inside thick and unprocessed tissue. It reveals how lipids, proteins, and blood components are organized within intact organs such as the placenta, preserving their natural architecture and biochemical context.
SRS combines structural and molecular information in a single, integrated view. It distinguishes collagen fibers, lipid domains, and small calcifications within tissue, revealing the chemical architecture that defines its morphology.
SRS visualizes molecular activity in living tissue without fluorescent labels. It captures how unlabeled drugs penetrate through skin and interact with lipid-rich layers, allowing molecular transport to be studied in real time under natural conditions.
SRS reveals biochemical patterns that remain invisible to conventional microscopy. In brain tissue, it highlights lipofuscin accumulations and other molecular features, exposing the chemical composition behind structural changes.
SRS distinguishes materials based on their unique vibrational spectra. Different types of microplastics or chemical compounds can be identified instantly, demonstrating the versatility of molecular imaging beyond biological research.
Instant insight
SRS provides the benefits of Raman spectroscopy without its limitations. It generates no fluorescent background, works with standard glass slides, and produces a linear signal that directly reflects molecular concentration. This enables quantitative analysis of chemical changes such as metabolism or drug uptake.
Molecular context
With a complete molecular spectrum in every pixel, SRS turns complex cellular reactions into clear, analyzable information. Changes in molecular composition and spatial organization reflect cellular dynamics and genetic alterations, linking structure and function and enabling analysis of cell states and compound effects.
