20,000 nm/second Tuning Speed

The Venturi TLB-8800 is the only swept wavelength laser with up 20,000 nm/second tuning speed and high frequency repetition rates enabling true real-time measurements. Tuning speeds, repetition rates, dwell times, and wavelength ranges are adjustable to accommodate your unique needs. In addition to wavelength sweeping, the Venturi is capable of step tuning in 0.01 nm increments. The front panel offers easy access to RS232 and USB interfacing with use of a user friendly GUI.

Compatible Power Sensors

To verify and analyze the output power of your Venturi laser, we recommend the Ophir PD300-IR (7Z02412) thermal power sensor and Centauri laser power meter.  Additional information on this laser measurement equipment can be found on the website.  Other Ophir sensors and meters may also be suitable for the Venturi, depending on application. Ophir also works with laser system developers to achieve embedded beam diagnostics to monitor system performance as an OEM solution.
