Laser coatings

For highly reflective mirrors, on the other hand, only dielectric coatings are used. These transmit the non-reflected part and can therefore achieve very low absorption values. These coating systems are optimized for one wavelength or one laser and thus achieve reflection values of up to 99.9%.

CO2 laser coatings

The coatings for CO2 lasers are designed and manufactured for the highest demands in industrial environments.
