NSG20
| High Resonant Frequency NONCONTACT "GOLDEN" Silicon Cantilevers NSG20 series |
- Standard chip size: 1.6x3.6x0.4 mm.
- High reflective Au coating (reflective property is 3 times better in comparison with uncoated cantilevers).
- Typical curvature radius of a tip: 10 nm.
- Tip height: 10 - 15 µm.
- Each chip has one TRIANGULAR spring.
- Recommended for semicontact modes and force lithography.
- Can be supplied with conductive TiN, W2C, Pt, Au coatings.
- Calibrated SEM photo for each cantilever tip with guaranteed curvature radius 10nm or less.
- Packaged in GelPak® boxes.
GelPak® is a registered trade mark of Vichem Corporation.

- Calibrated SEM photo for each cantilever tip and guaranteed curvature radius 10nm or less at customer's requirement ( cantilever series with letter "S" in the series name).
- Compatible with the most commercial SPM devices.
- Chemically stable Au coating.
- Silicon is doped by boron with the concentration about 5x1020 cm-3 to avoid electrostatic charges.
