ML6600 high-power laser system with multi-wavelength support

ML6600 is a laser system which supports up to 3 built-in lasers. ML6600 is controlled by a PC software or directly by analog/digital signals. ML6600 products are available in Modulight’s unique wavelength range from 400 to 2000 nm.

Laser light source – just plug-and-play 

ML6600 is a small plug-and-play laser system for users that don’t have time or interest for all the complexity with drivers, cooling, power supplies, etc. Just unbox it, and take into use!

ML6600 can have up to 3 lasers of different wavelengths built-in, or simply just one wavelength. When ordering, you may request 1–3 wavelengths from the below tables, or ask Modulight sales team for more options from the wavelength range 400–2000 nm. The laser light output comes conveniently from a  receptacle fiber with a standard SMA-905 connector.

ML6600 comes with a PC software with elegant graphic UI, or  alternatively it can be directly controlled by analog and digital control signals. Therefore it’s also suitable for the needs of system integrators.

Key features

  • Wavelengths: 400–2000 nm
