The Carpe is the first commercial autocorrelator to measure the pulse width of fs lasers at the output of laser microscopes behind the objective. The power of the laser behind the objective at the position of the sample can be measured as well with the power detector in the detector head.
The Carpe can measure the pulse width at both, the sample and the input position. This enables to examine the influence of the microscope optics on ultrafast pulses and to optimize the pulses at the relevant position. The Carpe works with high NA objectives as well as immersion objectives.
Due to the thickness of the detector cover, the minimum distance required between the focal point of the objective and the
housing of the objective (working distance) is 0.5 mm. To use objectives with a working distance below 0.5 mm, a short working option operating on a different detector principle is available.
The compact instrument is simply inserted into the beam between laser and microscope. It doesn't require any changes in the set-up and doesn’t interfere with the measuring beam.
Equipped with an optional spectrometer, the wavelength of the laser beam can be characterized as well.
Adjustment and menu controlled operation are very easy. The results are displayed at the control unit, which allows for data exchange to the PC and remote control of the Carpe via RS232 or USB interface.
