HighFinesse-Angstrom Wavelength Meters

High Finesse/Angstrom offers sensitive and compact wavelength meters with a large spectral range for high speed measurement of lasers. The optical unit consists of temperature-controlled interferometers that are read out by photodiode arrays. The high absolute accuracy is achieved by use of solid state, non-moving optics.

The optical unit and associated electronics are housed in a compact, thermal casing. The connection to a computer or notebook is realized via a high speed USB 2.0 port, which allows a high data read-out rate. The analyzing software displays all the interferometer information and is compatible with Microsoft Windows.


Standard features of the basic wavelength meters are:
Measurement of wavelength, frequency & co.

The measurement is displayed on the computer via the supplied user-friendly software. Installation and setup is straight forward. The displayed result may be switched between wavelength, frequency, wave number or -energy to suit the test requirements. The displayed interferometer pattern provides information regarding the spectral profile of pulsed or continuous wave laser sources.

Long-term measurement:
This application records all measurement results and displays it graphically along with calculating the mean, max. and min., as well as standard deviation. Many long-term windows can be open simultaneously to display all available information of up to 8 laser sources (multichannel option).

Record- and Replay Mode:
This operation mode records all interferometer data and allows for a subsequent play-back.

Two different arithmetic averaging techniques may be applied on 0 to 999 measurement points.

An easy access API provides a fast interface to all functionalities for controlling the WLM and accessing its data. Source code for sample programs is included.

Standard options include:

  • Linewidth option - L

  • Diffraction grating option - D

  • Double-pulse option - DP

  • Multi channel switcher (up to eight channels) - MC

  • External TTL trigger option - TTL

  • Lasercontrol output with PID-controller - PID
