Carpe Microscopy Autocorrelator

Carpe Microscopy Autocorrelatior

The APE Carpe autocorrelator is the first autocorrelator for microscopy applications.

While conventional instruments only define the laser pulse duration before the laser beam enters the microscope, Carpe autocorrelator measures pulse duration at both the sample and at the input position. So it becomes possible to examine the influence of the microscope optics on ultrafast pulses and to optimize them at the relevant spot. This measurement is possible at large numerical aperture (NA) and immersion objectives.

The Carpe autocorrelator can also be used for characterising the wavelength of the laser beam. The compact instrument is just inserted into the beam between laser and microscope. It requires no changes in the set up and does not interfere with the measuring beam. Adjustment and menu controlled operation are very easy. The results are displayed at the electronics unit. The integrated interface also allows for data transmission to the computer.

Short pulse option is also available with pulses down to <30fs in duration.

We also offer a variety of Microscope Accessories.
