Biophysics
Lasers enable high-precision manipulation, imaging, and analysis of biological structures without introducing chemical artifacts. CW lasers deliver stable, narrow-linewidth emission ideal for techniques such as optical trapping and tweezers, fluorescence excitation, and single-molecule spectroscopy.
Femtosecond and picosecond pulsed lasers enable nonlinear optical processes, including multiphoton excitation, time-resolved fluorescence, and ultrafast pump–probe studies.
Wavelength Versatility
Tunable wavelengths across the UV, Vis, and IR regions allow researchers to selectively excite specific molecular targets for a wide range of biological studies. Key research areas include femtosecond laser therapy, biophotonics, and photodynamic therapy.

“
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.
