waveScan USB

Pulse Diagnostics

A·P·E offers a choice of solutions for ultrafast pulse measurements. Each is tailored to your type of laser system, with a wealth of innovations for greater accuracy and user simplicity.


Via the waveScan technology, A·P·E offers a spectrum analyzer for different wavelength ranges of CW and mode-locked laser systems. Featuring high resolution and supreme ease of use, several versions of waveScan are available, to allow measurement of scan rages ranging from 200 ... 6300 nm.


The waveScan USB is an easy to use, high resolution device for spectral analysis of CW and mode-locked laser systems. With its resolution down to 0.1 nm for the Blue HR version, it offers greater precision over a larger wavelength range compared to standard compact CCD based spectrometers.

Especially in the spectral region longer 1.1 µm, which lies beyond the capability of silicon based CCDs, it offers an easy way for a high resolution measurement.

The waveScan USB is also an ideal alignment tool because of its high scan rates.

The waveScan USB is available in different versions covering scan ranges from 200 ... 2600 nm.

Equipped with a Software Interface (using TCP/IP) it can also easily be integrated into larger experimental setups and software controlled environments.

The easy-to-use Control Software supplied with the waveScan USB displays and stores the measured spectra on a standard PC (not included) and gives access to all measuring and calibration features.

The waveScan USB comes wavelength calibrated. A fiber input is optional.
