Low Temperature Piezoelectric Nano-scanning Table
| Goptica The NNxy-40-o-LT and NNz-40-o-LT are non-magnetic, compact, open-loop piezoelectric ceramic linear scanning tables suitable for use in extreme physical environments such as low temperatures, high vacuum and strong magnetic fields, with sub-nanometer resolution, unique piezoelectric amplifying mechanism design, and no crosstalk between uniaxial displacements. Provides a reliable scanning range of large strokes (>40 μm) at low temperatures and can be used in conjunction with the piezoelectric positioning stations of Goptica. Double-hole pin electrical interface, compatible with hyperfine closed-loop cryostat from Montana, Attocube and other well-known manufacturers.

 | Python GUI function introduction
1 Select the device communication port
2 Scan desk controls two channels of analog voltage output
3 Set the scan range and number of scan points
4 Select whether to Trigger the external test device. For example, if Yes, the controller sends a TTL trigger signal after scanning each point, and waits for the external device to send a signal indicating that the TTL data collection is complete

| Application Case 1: Second Harmonic confocal Microscope (Source: Institute of Chinese Academy of Sciences) |
| In this case, NNxy-40-o-LT was used to scan the growth and transport process of iron domains in periodically polarized lithium niobate films (PPLN) under high voltage pulse. The ultra-fine map scanning and imaging of iron domain growth in PPLN can be performed by using NNXY-40-O-LT at room temperature with high resolution and large scanning range above 90um. |

| Application Case 2: Low temperature photofluorescence spectroscopy (Source: Institute of Chinese Academy of Sciences) |
| In this case, NNxy-40-o-LT was used to perform hyfine and high dynamic two-dimensional spectral imaging of photoinduced fluorescence spectra of self-mounted quantum dots and solid color centers. At 4K temperatures, the NNxy-40-o-LT provides unmatched high precision solid-state atomic spectral imaging scanning with independent multi-axis motion and no crosstalk. |
