 Datasheet

Overview

The pulseCheck SM (Stepper Motor) autocorrelator is a versatile instrument for measuring the pulse width of different fs and ps laser systems, with the ability to cover a broad wavelength range and expanding the APE Autocorrelators suite scan ranges to 1600 ps.

The wavelength range can be upgraded in the field. Please contact us for more information on possible upgrades.
 APE also offers customer-specific modifications.
