ITO (Indium Tin Oxide) coatings can be applied on glass as well as on plastic.
- On plastic ITO is applied under vacuum at lower temperature. Surface conductivities up to < 10 Ohm-square can be reached.
- On glass a higher temperature can be used and therefore surface resistance can be reduced to < 2,5 Ohm-square.
ITO coated windows are mainly applied for:
- EMI/RFI shielding
- ESD (protection against electro static discharge)
- heated optical filters for displays
- active components for touch-screens
Antireflection possibilities with mineral glass
- Multi-layer coating according to MIL SPEC 675 B (less than 0,6% rest of reflection)
- Single-layer coating according to DIN 58197 (less than 1,5% rest of reflection)
- Chemical etching:
5% anti reflecion (called GW 80)
9% anti reflection (called GW 100)
13% anti reflection (called GW 120)
Antireflection possibilities with plastic substrates
- Multi-layer coating according to MIL SPEC 675 B (less than 0,6% rest of reflection)
- Single-layer coating according to DIN 58197 (less than 1,5% rest of reflection)Chemical etching (very diffuse)
- Chemical etching (very diffuse)
- Anti-scratch, anti-reflection coating by spraying
