Laser-Driven Tunable Light Source 

The TLS-EQ-9 is a tunable light source optimized to provide monochromatic light across a broad wavelength range.

The TLS-EQ-9 is based on the EQ-9 LDLS, offering mid-range output power in a flexible, easy-to-use package. 

The spectral resolution of the TLS-EQ-9 is user-configurable, allowing users to select different bandwidths for different applications. The stable performance of the TLS-EQ-9 translates to consistent, reliable results. The fast step time and high brightness of the TLS-EQ-9 enable high process throughput.

Users will find the TLS-EQ-9 to be extremely easy to use and maintain. The intuitive graphic user interface (GUI) allows for the creation of automated scans to rapidly step between prescribed wavelength bands. The fiber-coupled output of the TLS-EQ-9 makes it simple to integrate into a variety of optical configurations.
