HighFinesse WR series

Rack integrated wavelength meter

The HighFinesse WR-Series Wavelength Meters are available in compact 19-inch rack housings and can seamlessly integrate into your standard rack system. With just 3 HU, they offer a space-saving solution that fits perfectly into laboratory and measurement environments.

When combined with the Photonic Crystal Switch (1 HU), the WR-Series can measure up to eight lasers quasi simultaneously. An optional calibration source can also be integrated. This makes the WR-Series especially well-suited for applications requiring the precise and synchronized monitoring of multiple laser sources.

With a measurement range from 192 to 1750 nm, the WR-Series covers a broad wavelength range.

The modular design allows for further expansion with options such as the Photonic Crystal Switch or PID Laser Control, enabling flexible adaptation to your specific requirements.

The build in External Trigger (ET) capability guarantees synchronization between pulsed excitation and measurement. It provides low-noise signals without parasitic parts when measuring pulsed signals with low duty cycles.

The rack-mounted wavelength meters connect to an external computer via USB, ensuring easy integration into existing systems. Thanks to their compact design they save valuable workspace in the lab – no more cable or fiber clutter. Simply plug in, connect, and start measuring.

Options

Photonic Crystal Switch Rack
Combining our wavelength meters with the Photonic Crystal Switch Rack enables quasi-simultaneous measurement of up to eight wavelengths. Exposure time and other parameters can be set individually for each light source.
Analog PID
The analog PID allows to control all lasers with a suitable analog input at the laser controller (impedance >10 kOhm).
Digital PID
The digital PID option allows to control all Toptica lasers compatible with the DLC Pro Controller. The communication is done via Ethernet avoiding the need for additional cables.
L (Linewidth)
The linewidth estimation of a singlemode laser source is performed by a special algorithm which eliminates the interferometer’s instrument response function. The algorithm enables the estimation of the linewidth with an accuracy better than the tenth of the instrumentʼs FSR. If you are interested in linewidth and noise characterization of narrow linewidth lasers below 100 MHz you might be interested in our linewidth analyzers (LWA).
Calibration Source
HighFinesse Stabilized Laser References incorporate absorption spectroscopy systems, which yield extremely accurate frequency stabilizations, ideal for calibration of our wavelength meters in the visible and infrared wavelength regimes.
