ハイフィネス波長計は、パルス及びCWレーザー光源の波長測定ができる唯一無二のハイエンドな測定装置です。産業、医療分野でのアプリケーション同様、理科学研究分野の最先端で要求される高い絶対精度及び相対精度をご提供します。
2MHzの絶対精度、200kHz以下の測定分解能まで実現する超精密なWS8シリーズは、ユニークな幾何学構造で、可動部の無いフィゾー干渉計を応用することにより実現します。ハイフィネスの波長計は全て、この既知の概念を利用します。いっそう高い安定性と精度を可能にするために、温度及び気圧の影響は補正されています。ハイフィネスはまた、市販が可能な最高速の波長計も供給します。追加情報は ここ をクリックしてください。波長計の感度をnJまで下げることに達成し、一方で、レーザーの波長をコントロールするために、アクティブフィードバックをするPIDレーザーコントロールのような有益なオプションをご用意しています。

Options
TTL
External TriggerAll wavelength meters detect and measure pulsed signals automatically. Additionally, this option allows the user to trigger pulsed measurements externally. The TTL option guarantees synchronization between pulsed excitation and measurement.
PID
Laser ControlWith the PID option it is possible to stabilize the frequency of a laser connected to the wavelength meter using a software based proportional-integral-derivative controller (PID controller). Unlike analog PID electronics, the PID option provides software based signal processing, allowing the laser to be stabilized to a specific user defined frequency or regulated with an arbitrary pattern.
MC
MultiplexerIn order to measure the frequencies of more than just one laser at a time, an opto-mechanical switch is used. The combination of our high-speed wavelength meters with one of the quickest fiber switches (MEMS) available allows up to eight channels to be measured almost simultaneously.
L
Linewidth EstimationThe 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 instrument FSR.
D
SpectrometerThe spectrometer option allows the analysis of emission spectra to an accuracy of 6 GHz, for laser sources with broad emission. The software automatically searches the spectral section where the laser emission line is located and displays it on the screen. In combination with the additional Fizeau interferometer array this allows wide range applications with a single instrument.
CAL
External CalibrationStandard 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.
