Standard Coating for Plastic Optics

Optical coatings are used to reflect, direct and filter light, prevent light reflection, protect surfaces, and improve the quality of optical components. GPT Optics is your expert partner in the design, manufacture, and coating of polymer-based optical components and systems.

Coatings:

MgF2 Single Layer

• Multi Layer Broad Band A/R
• Aluminum, Silver, Gold
• Dielectric
• Sio ZnSe
• V Coats

Plastics have established themselves as a material for optical components. LED reflectors, components for medical technologies and many other elements can be implemented cost efficient and in large quantities.

An optical coating can improve the physical characteristics and features of a plastic lens. Not only the control of the optical properties, such as an anti-reflection or reflections, but also the mechanical and chemical properties can be influenced. By the optical coating the plastic optics is resistant to gases and moisture.

For the coating of the optical components, we use the physical vapor deposition, the PVD. Modern software tools and a coating system from Optics enable the calculation and optimization of the optical properties and features.

The following optical functions can be achieved by optical coating:

• antireflection (AR) for anti-reflection
• reflex increase (HR) for reflections and filters
• Hardcoating to increase the scratch resistance, for example glassy hardness of coating with SiO2
• Topcoat for chemical functionalization
