Fastest Commercially Available Wavelength Meter

Manufacturer: HighFinesse. Distribution: TOPTICA.

Wavelength Meter “WS Fast series” with ultra high speed measurement rates, the fastest commercially available device of its kind. It combines excellent accuracy with a maximum data acquisition rate of up to 76 kHz.

The data acquisition allows fast dynamics in the kHz range to be directly observed. Different measurement modes enable the user to record or view the frequency behavior of the light source. External triggering allows the user to synchronize wavelength measurement with external setup by means of TTL pulses. The light sensitive sensors are prepared for measurement up to a specifiable integration time after the arrival of the external trigger pulse.

The optical unit consists of Fizeau-based interferometers which are read out by photodiode arrays. Thus, it achieves remarkable high accuracy and stability by using exclusive, non-moving optics. The sturdiness of the design has been proven even under extreme conditions such as freefall dropping experiments or in air-borne applications (LIDAR). The absence of movable parts ensures our most valued advantages, e.g. high-speed measurements of pulsed and continuous lasers.
