Hydrophobic Tablet (HT-100)

HT-100 has been developed to obtain a thin film with water repellence. HT-100 can be deposited on to A-R layer on glass or plastic lens in a vacuum coating machine. As the result, lenses coated with HT-100 are less susceptible to soil and are easier to clean. They are especially less sensitive to finger marks which have a strong interfering effect on multi coated lens.

Usage of electron beam

• General conditions
  I) Vacuum condition: 2 x 10^-5 mbar
  II) Substrates (lens) temperature: 80°C
  III) Coating thickness 5-20nm for 30-60 sec.
  IV) The contact angle for water: 200°C
  
• Processing of plastic lens
  * Plastic lens
  Start the lowest beam power (7-11 Amp. 30sec - 60sec)
  Coating thickness is between 5nm-20nm
  ** Do not contact ION beam on the HT-100 coated surface.
  
• Processing of glass lens
  Glass lens
  The same processing as the plastic lens
  But you have to change coating design.
  In this case, we can send the glass lens coating design to our manufacture hydrophobic tablet.

• General conditions: the same as electron beam
• Processing of plastic lens
  Evaporation temperature : 200°C - 400°C
  Boat: Box shaped, molybdenum boat
• Processing of glass lens: the same as plastic lens
