WEO’s optical coating includes various anti-reflection, high reflection, beam splitter, and filter coatings.

Suitable applications:

THE COATING PROCESS

The coating process is done by physical vapour deposition techniques. Whenever necessary, IAD (Ion-assist deposition) process is used to enhance the coating film hardness and durability.

DURABILITY & ADHESION

Coating witness piece and spectral result are accompanied with products delivered to customer.

Coating durability and adhesion are tested based on customer requirements.
