An autofocus system for femto/pico second pulsed lasers based on the coherence between incident and reflected light from the sample.
- Automatic focusing : no human intervention (delay line embedded)
- Accurate : the sample is in the exact focal point, even for rugged surfaces
- Adaptable : no need to change anything when working on new samples
- Fast : the tuning is made in few seconds
- Contactless : adjustments are made remotely with light feedback in a meter range
- Polyvalent : it works for a large range of wavelength
