HQ-150-Au

High Quality (HQ)™ AFM Probes
Get better results and ease of use with budget-priced AFM probes. Comparable with more expensive probes such as Tap150 and NCST, Asylum Research HQ™ probes are part of Asylum's proprietary SurfRider™ budget-priced probe line: they're a good choice for almost all routine AFM measurements and ideal for AFM training and educational use.

KEY FEATURES

• Value-priced to make your research budget go farther
• Vertical edges make probes easier to handle with tweezers
• Better consistency compared to other similarly priced probes
• Compatible with blueDrive™, GetReal™, and GetStarted™ for simpler operation
• The industry’s best customer support will help you select the optimal probe type

ASYLUM RESEARCH PROBE MECHANICS
Asylum Research delivers higher quality, more consistent probes at competitive prices by using modern, highly-controlled silicon fabrication tools and facilities:

• Stepper lithography instead of traditional mask aligner
• Almost 10X more precise compared with regular photo lithography
• Individual probe chips are separated with vertical edges
• Eliminate chipping and resulted coupling noise issue
• Deep reactive ion etching instead of conventional KOH etching
• Yields well defined cantilever geometry for better mechanical property
