DT-NCHR

Diamond Coated Tip - Non-Contact/Tapping Mode - High Resonance Frequency - Reflex Coating

NANOSENSORS™ DT-NCHR probes are designed for non-contact mode or tapping mode AFM (also known as: attractive or dynamic mode). This probe type combines high operation stability with outstanding sensitivity and fast scanning ability.

For applications that require hard contact between tip and sample this SPM probe offers a real diamond tip-side coating. This coating features extremely high wear resistance due to the unsurpassed hardness of diamond. The typical macroscopic tip radius of curvature lies is between 100 and 200 nm. Nanoroughnesses in the 10 nm regime improve the resolution on flat surfaces.

The probe offers unique features:

  • real diamond coating
  • tip height 10 - 15 µm
  • high mechanical Q-factor for high sensitivity

The DT Diamond Coating is an approximately 100 nm thick coating of polycrystalline diamond on the tip-side of the cantilever leading to an unsurpassed hardness of the tip. The raman spectrum of the coating verifies the real diamond.

The reflex coating is an approximately 30 nm thick aluminum coating on the detector side of the cantilever which enhances the reflectivity of the laser beam by a factor of about 2.5. Furthermore it prevents light from interfering within the cantilever. The virtually stress-free coating is bending the cantilever less than 3.5% of the cantilever length.
