High Precision Wavelength Measurement

The HighFinesse/Ångstrom WS7-30 is a high-end instrument for wavelength measurement of pulsed or continuous laser sources. It delivers excellent absolute and relative accuracy required by cutting-edge scientific research, as well as industrial and medical applications.

Photonic Crystal Switch

Photonic Crystal Switch

The photonic fiber switch at the input offers endlessly singlemode operation, making it possible to measure lasers at wavelengths across the entire spectrum with the full accuracy of the wavelength meter.

Ease of Use & Customization

Icon Plug & Play via USB Connection Icon Customization Possible

The WS8 is connected to the PC via a USB interface and is ready for use as soon as the software delivered with the device is installed. The design enables the integration of additional options, allowing customized solutions to specific applications.

Typical Applications

The WS7-30 is one of our high-end solutions for wavelength monitoring and control with an absolute accuracy of 30 MHz and a wavelength deviation sensitivity of 1 MHz. It perfectly combines with the photonic crystal fiber technology enabling multichannel operation in the spectral range of the wavelength meter. The 30 MHz presumes, that the device is supported by one of our calibration sources.

Available Measurement Ranges

Icon Measurement Range 248 – 1180 nm


Icon Measurement Range 330 – 1180 nm


Icon Measurement Range 630 – 1750 nm


Icon Measurement Range 1000 – 2250 nm


Icon Option CAL – External Calibration

External Calibration

Standard HighFinesse wavelength meters up to an absolute accuracy of 60 MHz feature autocalibration via an integrated calibration source. This guarantees the accuracy and stability of measurements with our wavelength meters. For the higher accuracies we offer a variety of frequency stabilized, narrow linewidth, laser sources with up to ± 10 kHz frequency stability for different applications.

Additional Options

Icon Option TTL – External Trigger Icon Option PID – Lasercontrol Icon Option L – Linewidth Estimation

Please note, if the option MC is ordered together with the TTL option, the TTL mode can only be used if the switch is set fixed to one input channel.


HighFinesse offers the WS7-30-series as compact device, standalone device, in a 19-Inch rack-mount case or customized to your needs.
