ML6600 – Cloud-powered Laser Solution Platform

ML6600 - Cloud-Powered Laser Solution Platform

ML6600 is an established product platform, originally launched in 2013. ML6600 can host different laser technologies (diode, fiber, DPSS). Specifications will be tailored to the application. Wavelength in the range from UV to 2+ µm, power from mW up to 100 W, and linewidths down to kHz.

Easy-to-integrate light engine

ML6600 is a compact, easy-to-integrate laser solution that can be flexibly tailored to various applications, such as Flow Cytometry, Semiconductor Metrology, Quantum Computing, Diagnostics, Genetics, and various medical applications.

It’s well suited for medical system integrators, as it’s designed in accordance with IEC 60601-1 norm. This will speed up the certification process. The lasers and the system are manufactured in ISO13485 certified fab.

The platform supports preventive maintenance with predictive analytics and machine learning algorithms, powered by Modulight Cloud. The network connection can be established via Wi-Fi, Ethernet, or cellular connection.

ML6600 platform can host multiple lasers of different wavelengths, or simply just one wavelength. When ordering, you may request any combination of wavelengths from the below tables, or ask Modulight sales team for more options from the wavelength range UV to 2000+ nm. The laser light output comes conveniently from fiber pigtail or receptacle fiber with a standard SMA-905 connector. Other connectors are available per request.

As a part of the light engine, Modulight can provide customized optical solutions for laser beam delivery and shaping.

Subsystem or stand-alone

For system integrators ML6600 is available as a subsystem which can be directly controlled by analog and digital control signals, through RS422, RS232 or Ethernet.

ML6600 can also act as a stand-alone version, which comes with a PC software with elegant graphic UI.



Flow Cytometry

Flow cytometry is a widely used method in biomedical research to detect, characterize, and sort particles such as cells as they are suspended in liquid and pass in a narrow line across laser beams. Lasers are used for illuminating samples in flow cytometry because they provide very focused, noise-free, and monochromatic illumination.

Semiconductor Metrology

Non-destructive optical measurement technology offers ultra-precise measurement and analysis for medical, semiconductor and electronics industries. Non-contactless high precision distance, thickness and other dimensions measurements can play essential role in device quality control process.

Quantum computing

Laser light sources are at the heart of quantum networks, enabling photons to act as carriers of quantum states. Modulight offers the required extreme level of accuracy, control, and innovation for delivering the solutions for tomorrow’s quantum computers – starting from a single laser to complex and powerful solutions by using the Modulight decades of knowledge.


Fluorescence diagnostic imaging is a fairly new technique that utilizes a photosensitizing compound to visualize only specific tissue structures upon illumination with certain wavelength of light. The benefits of fluorescence imaging lay in high detection sensitivity, specificity, and spatial resolution and it is considered a great addition to traditional white light endoscopy (WLE).


The most widely used sequencing platforms rely on optical detection of the four bases of DNA. The bases are conjugated to different fluorophores that emit specific color when excited by the laser light (both green and red lasers are used). Typically each laser excites two different fluorophores that have overlapping absorption spectra.
