The Laser Quantum ventus family of CW lasers is designed to exceed the demands of the scientific customer where flexibility, reliability and beam quality are critical. Each laser is highly compact, and can be operated via the control unit, simple software, Labview or with the Laser Quantum RemoteApp software that allows operation across the internet, and even connection for optimisation procedures.

With MTTF figures in the hundreds of thousand hours, each laser is rigorously tested for impact resistance via a drop test, temperature and power cycling to ensure that every delivery works first time and exhibits long trouble free lifetimes.

With a wavelength range covering 473 nm to 1064 nm and powers from 50 mW to 1.5 W, all within the same housing, the ventus family is ideal for research applications in biomedical imaging, microscopy, Raman spectroscopy, DNA sequencing, optogenetics and anywhere a high specification, reliable laser is needed.
