Flexible, Stable Tunable Broadband Light Source


Flexible Spectral Resolution & High Throughput Results

The TLS-EQ-9-S 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-S is user-configurable, allowing users to select different bandwidths for different applications. The stable performance of the TLS-EQ-9-S translates to consistent, reliable results, while the fast step time and high brightness enable high process throughput.
TLS-EQ-9-S is 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-S makes it simple to integrate into a variety of optical configurations.
