Pointprobe® Series AFM Tips - Available Coatings

Aluminum Reflex Coating

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

Hard Magnetic Coating

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

Soft Magnetic Coating

• soft magnetic coating on the tip side of the AFM cantilever
• coercivity of app. 0.75 Oe
• remanence magnetization of app. 225 emu/cm3
• AFM 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 AFM cantilever
• unsurpassed hardness of the AFM tip
• resistance < 10 kOhm for CDT

Platinum Iridium5 Coating

• 25 nm thick platinum iridium5 coating on both sides of the AFM 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 AFM cantilever enhances reflectance of the laser beam
• 70 nm thick gold coating on both sides of the AFM probe
