Aspire – Experience the Conical Advantage™
The geometry of an AFM tip plays an important role when imaging surfaces. The use of a uniform, conical tip guarantees that you’re acquiring truly symmetrical images. A conical shape is especially beneficial when imaging membranes (holes) and pillar structures, or random structures with surface roughness. Aspire™ AFM probes are the first conically-shaped AFM tips for the mass-market. Manufactured from high-quality, highly doped, single crystal silicon, these probes are robust and offer long imaging life.
Aspire probe model CT130 is designed for tapping mode applications and features a softer spring constant (6 N/m) while maintaining a mid-range resonance frequency (130 kHz). Typical tip radius is 8 nm. An industry-standard chip design guarantees compatibility with all standard AFM chip holders and also the pre-aligned holders on Nanosurf AFMs. Model CT130R probes have an aluminum Reflex coating on the cantilever’s detector side. The coating improves laser reflection and does not coat the cantilever’s tip.
Please contact us about packaging options for half wafers (200 probes) and full wafers (400 probes).
