Omicron‘s LaserNest® has evolved from the high performance LuxX+ series that simplifies its use in laboratory and life science applications. Omicron’s electronic modulation capabilities are unrivalled, with fast analogue intensity modulation with up to 3MHz and high-speed digital modulation up to 250MHz. The electronic shutter function provides full ON/OFF modulation with a switching time of <1µs and frequencies up to 500kHz, a feature that is still unrivalled by competitors.

A range of output interfaces is available, including single-mode PM fibre, multimode fibre or Liquid Light Guide.

LaserNest® has a range of power outputs available, up to 500 milliwatt, and more than 30 different wavelengths between 375 and 1550nm. Other options available include clean-up filters and a fail-safe laser safety shutter. Modulation inputs with software selectable voltage ranges and impedance ensure easy interfacing to external devices like cameras, microscopes or DAC cards. The system can be controlled via the integrated USB-2.0 interface using either Omicron’s Control Center (OCC) or third party software.
