PPP-ZEILR

Product Description:

The new PointProbe® Plus (PPP) combines the well-known features of the proven PointProbe® series such as high application versatility and compatibility with most commercial SPMs with a further reduced and more reproducible tip radius as well as a more defined tip shape. The typical tip radius of less than 7 nm and the minimized variation in tip shape provide more reproducible images and enhanced resolution.For owners of a Zeiss Veritekt or Seiko Instruments microscope using contact mode we recommend NANOSENSORS^™ PPP-ZEILR (Zeiss Veritekt / low force constant). Compared to the contact mode AFM probe (CONT) the force constant is slightly increased. 
    The probe offers unique features:
        - excellent tip radius of curvature
        - highly doped to dissipate static charge
        - Al coating on detector side of cantilever
        - high mechanical Q-factor for high sensitivity

Application Modes:

• Contact Mode AFM Probes

Coating:

The reflex coating is an approximately 30 nm thick aluminium 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 stres-free coating is bending the cantilever less than 2% of the cantilever length.
