IR-reflective mirror coating for optical sensors

Polyteknik Coating can provide a thin film high-reflective mirror coating with excellent ageing properties, capable of withstanding ambient conditions, such as humid climate and air pollution.

Optical gas sensor devices are often built from injection-moulded thermoplastics where the chamber walls of the sensor is deposited with either gold, silver, aluminium, nickel or copper.

While aluminium has at least 94% reflectivity at wavelenghts above 1000 nm, gold and siver have at least 98% reflectivity at wavelengths above 800 nm.

In order to prevent ageing and oxidisation, Polyteknik can provide all coatings with a protective top layer, which ensures outstanding ageing properties.
