PicoQuant has introduced the Prima that generates laser light at 635, 510 and 450 nm with each colour being emitted individually, one at a time. These three wavelengths cover most of the excitation needs for routine excitation in spectroscopy or microscopy applications. The new laser module supports pulsed operation with repetition rates up to 200 MHz, continuous wave (CW) mode as well as fast switching CW capability with a rise/fall time of <3 ns. In pulsed mode, each wavelength can achieve an average optical output power of typically 5 mW, and up to 50 mW in CW mode. The Prima does not require any additional laser driver. All settings and operating parameters are fully computer controlled via a WindowsTM based control software.
