Laser-Driven Tunable Light Source 

The TLS-EQ-9 is a flexible wavelength tunable device built around Energetiq’s Laser-Driven Light Source (LDLS™) platform. This exciting technology gives the user access to a wide wavelength range of tunability, high spectral resolution and an extremely long lifetime with the added benefit of a convenient fiber-coupled output.

The TLS-EQ-9 model is based on the EQ-9 LDLS, offering mid-range output power in a flexible, easy-to-use package. The broad wavelength range of the TLS-EQ-9 provides bright output from 380 nm to 1100 nm, covering the visible wavelength range into the near infrared (NIR). 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 graphical 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. The TLS-EQ-9 can run 24 hours a day and seven days per week (24/7) for over a year between bulb changes.
