Aluminum Reflex Coating

  • 30 nm thick aluminum reflex coating on the detector side of the cantilever
  • enhances reflectance of the laser beam by a factor of 2.5
  • prevents light from interfering within the cantilever
  • strongly recommended for thin cantilevers if the coating is compatible with the application

Hard Magnetic Coating

  • cobalt alloy coating on the tip side of the cantilever
  • permanent magnetization of the tip
  • tip needs to be magnetized by means of an external strong magnet prior to measurement
  • soft magnetic samples may be influenced by the tip magnetization

Soft Magnetic Coating

  • soft magnetic coating on the tip side of the cantilever
  • coercivity of app. 0.75 Oe
  • remanence magnetization of app. 225 emu/cm3
  • tip needs to be magnetized by means of an external strong magnet prior to measurement

Diamond Coating

  • 100 nm thick polycrystalline diamond coating on the tip side of the cantilever
  • unsurpassed hardness of the tip
  • resistance < 10 kOhm for CDT

Platinum Iridium5 Coating

  • 25 nm thick platinum iridium5 coating on both sides of the probe
  • tip side coating enhances conductivity and allows electrical measurements
  • detector side coating enhances reflectance of the laser beam by a factor of 2
  • stress compensated and wear resistant

Gold Coating (on request)

  • 70 nm gold reflex coating on the detector side of the cantilever enhances reflectance of the laser beam
  • 70 nm thick gold coating on both sides of the probe
