Ophtalmic Phasium Clear Control

 

Ophtalmic Phasium Clear Control, new anti-stains treatment Launched at the Silmo, the new treatment anti-stains Phasium DC of Ophtalmic, is based on the last technology from the manufacturer Satis Vacuum, leader in vacuum treatments, who offer performances among the best in the market. Phasium DC is a anti-reflection coating treatment and 8 layers which is pressed on a hardened layer of silica, this fine layer guarantee the behaviour of the treatment and its scratch resistance

Hydrophobia and oleophobia


Phasium Clear Central presents on the surface a particularly hydrophobic fluorinated micro-layer allowing a reduction in the surface of contact between the drops of water or grease. The angle contact between a water drop and surfaces, the treated makes it possible to evaluate the hydrophobic performances of a treatment. With an angle of 118 ° against 108 ° for traditional coating, this treatment ensures a facilitated wiping.

 

 

 

 

Anti-adhesive and anti-static properties
Surface smoothes particularly anti adhesive makes it possible to avoid hangs it resins and greases, a simple test consists in trying to stick Post-it® on glass: it is possible on a normal anti-reflection coating and impossible on hydrophobic Phasium DC
With the traditional anti-reflection coating, treated surfaces can take care of the static electricity, in particular because of friction at the cleaning time. This static electricity stuck dust and other impurities. Phasium DC have in it's composition conducting elements which ensure the dissipation of the electrostatic loads.

Better abrasion resistance
The hardened layer of high indices makes Phasium DC particularly powerful for materials of strong index, offering at the same time a better connection substrate - layers AR and a better optical quality (absence of newton's rings), The reduction of the cycles of cleanings is obtained through the properties anti-stains of Phasium DC and limit naturally risks of abrasion.

The range Phasium DC
Phasium DC will be available on a lot of materials (organics 150 to 1,74) and of 4 materials in polycarbonate atoric Resolution, organics 1.50, 1.60 (MR8) and 1,67 aspheric
