PicoScale Sensor Heads
The PicoScale sensor heads are mandatory equipment to perform high resolution displacement measurements with your PicoScale. Within the heads, the interference pattern is formed, which contains the information on the target mirror’s position.
SmarAct offers a selection of sensor heads for most applications. However, we can customize the heads for your needs:
- Differential measurements. Due to the Michelson principle, SmarAct’s sensor heads have an intrinsically stable reference arm as the reference mirror is directly coated to the beam splitter. When omitted, the Michelson principle allows to perform differential displacement measurements of two target mirrors, which is not possible with other interferometric displacement measurements based on a Fabry-Pérot interferometer.
- High vacuum (down to 10-6 mbar) or ultra high vacuum (10-11 mbar) compatibility.
- The sensor head can be designed so that the probe beam is perpendicular to the standard axis to be integrated in experimental setups with specific space constraints.
