d-scan is an inline, compact and high-performance device for the simultaneous measurement and compression of even the most demanding ultrafast pulses. d-scan can be used either as a standalone system or integrated with existing optical pulse compressors. It handles broadband oscillators, amplifiers, OPAs and hollow-fiber compressors.

Coupling your beam into the d-scan is easily achieved in less than one minute and a full measurement takes less than 10 seconds. 

The resulting d-scan traces are very intuitive and a proprietary retrieval algorithm provides fast and accurate retrieval of the full electric field of your compressed ultrafast pulses.

The d-shot is a compact system for ultrafast laser pulses single shot measurement with spectrum supporting 10-50 fs and at repetition rates ranging from sub-Hz to hundreds of kHz or MHz. 

Coupling the laser beam into the d-shot is easily achieved in less than five minutes, and a full measurement usually takes less than 10 seconds. 

The intuitiveness of the d-shot trace provides instant visual feedback for the optimisation of your source. 

A proprietary retrieval algorithm provides fast and accurate retrieval of the full electric field of the pulses.

No need anymore to stitch together two different sensors to cover the bandwidth around 1050nm, d-vision does it with just one air cooled sensor. Thanks to our technology we are able to provide you a spectrometer with a reduced size and price, what could you wish more?

d-vision can cover the bandwidth going from 600nm up to 1700nm, with resolutions going from 3nm to 1nm, depending on the grating selection. Our software is easy-to-use, intuitive and have all the features to make your measurement a simple task

Ensuring optimum pulse compression at the sample is not an easy task, and is harder to do for shorter pulses. Sphere’s d-micro was especially developed to solve this problem by simultaneously compressing the pulse and ensuring optimum duration directly at the sample plane, even for the most demanding laser pulses.

The d-micro comprises two COMPACT modules:
– the COMPRESSOR, which allows pre-compensating the dispersion introduced by the microscope
– the MEASURING HEAD, which measures the pulse directly at the sample position.
