Microscopy
Microscopy enables researchers to visualize biological, chemical, and material systems with extraordinary spatial resolution and sensitivity. Advanced techniques such as fluorescence, Raman, multiphoton, nonlinear, and single-molecule microscopy reveal structures and processes that are invisible to conventional imaging. Tunable laser sources provide the flexibility needed to optimize contrast, depth penetration, and molecular specificity.
Single-Molecule Microscopy
Observing individual molecules provides a unique window into the fundamental processes that govern biological and chemical systems. By tracking molecular interactions, dynamics, and structural changes at the single-molecule level, researchers can uncover details that are often hidden in ensemble measurements. Tunable laser sources enable precise excitation of fluorescent probes, enhancing sensitivity and expanding the range of molecules and processes that can be studied.
Raman Microscopy
Raman microscopy combines high-resolution imaging with molecular-level chemical analysis, revealing the composition and structure of samples without the need for labels or dyes. By mapping molecular vibrations across a specimen, researchers can study biological tissues, advanced materials, and chemical processes with exceptional specificity.
Time-Resolved Fluorescence Microscopy
Following how fluorescence evolves over time reveals information that cannot be obtained from intensity measurements alone. By monitoring fluorescence lifetimes, researchers can investigate molecular interactions, cellular environments, and biological dynamics with exceptional sensitivity. Tunable laser sources provide the flexibility to selectively excite fluorescent probes, enabling more detailed and quantitative imaging of complex biological systems.
Two-Photon Microscopy
Exploring deep within biological tissues requires imaging techniques that combine high resolution with minimal photodamage. By using the simultaneous absorption of two photons to excite fluorescence, researchers can visualize structures and processes far below the sample surface with exceptional contrast. Tunable laser sources enable efficient excitation across different fluorophores, supporting advanced imaging in neuroscience, developmental biology, and biomedical research.
Fluorescence Microscopy
Visualizing specific structures and processes within complex samples has transformed the study of biological and material systems. By detecting the light emitted from fluorescent markers, researchers can achieve high-contrast imaging with excellent specificity. This approach enables detailed investigation of cells, tissues, and dynamic processes, providing valuable insight into the organization and function of complex systems.

“
Radiantis were very flexible with our requirements and perfectly matched to our technical needs and budget. Radiantis OPO has enabled us to carry out advanced optical characterisation of our systems across the UV, Visible and IR, and has proven to be a very reliable and easy-to-use system, delivering high and stable power and fast automated tuning across the complete spectral range. Radiantis team were very friendly and provided a professional and comprehensive user training to key researchers in my lab, which enabled us to operate the OPO successfully and reliably over many years.

The wide tuning range of our Radiantis OPO system has allowed us to access wavelength regimes that have enabled a number of nonlinear optics experiments that would otherwise not have been possible. Radiantis have been very responsive and any problems have always been dealt with swiftly, with engineers being sent over to our lab for extended visits whenever required.
