Planti makes Anti-reflect coating with Sol-gel process.
The procedure consists of 2 parts: the Sol (solution) and the Gel. The Sol forms the gel, and the gel is applied as a coating to the substrate and is dried to create a hard, glossy film. The coatings are deposited using the dip coating method, at a withdrawal speed of 5 cm/min. All coatings are dried for 20 min under air conditions. Finally, these films are annealed at different temperatures for 20 min. and taken out from the oven after cooling at ambient temperature.
