Contact us"We can perform about 90% of our spectroscopy experiments with the three excitation wavelengths provided by Prima. Prima can greatly simplify our optical set-up thanks to its small size and fiber output, which facilitates its use."

Prima is a solution for researchers who
- need more than one wavelength
- don't have space in the lab
- measure a short decay time (ns) and a long one (µs-ms)
- deal with materials that have a poor luminescence quantum yield
- would like to avoid daily alignment and laser maintenance
Red, green, and blue: the three most utilized wavelengths
Each colour can be generated individually, one at a time. These wavelengths are the three most commonly used in materials science, chemistry and life science for routine excitation in spectroscopy or microscopy applications to study a wide range of samples, including novel nanomaterials or quantum dots.
Pulsed, CW, and fast switched emission modes
Prima offers full flexibility, enabling you to perform time-resolved or steady-state measurements. Fast cw switching is a smart solution for measuring longer lifetimes in the µs to ms range. It is especially efficient for materials with a poor luminescence quantum yield. The pulsed mode can be driven either internally at selected repetition rates between 100 Hz and 200 MHz or externally, with rates ranging from single shot up to 200 MHz. Moreover, you can combine Prima with other laser diode heads to create even more sophisticated excitation patterns, such as bursts, Pulse Interleaved Excitation (PIE), or Alternative Laser Excitation (ALEX).
