Whether in series production or in custom manufacturing of specific optics components – the highest quality standards and constant innovation guarantee you flawless optics that make the difference in your areas of application.

Laser optics

The coated laser optics are required in many optical industries. With the help of optical coatings, the reflectivity of surfaces can be controlled and specifically influenced for the area of application. In the field of laser optics, a distinction is made between metallic and dielectric coatings. The distinction is based on the coating material. In the case of metallic coatings, for example, aluminum or silver is used for the production of reflectors. Dielectric coatings are used to maximize reflection. The physical properties of the metals used determine the reflectivity.

Coating Service for Supplies

We apply high-quality metal coatings—such as gold, silver, aluminum, platinum, and rhodium—to supplied optical components.

Our coatings are designed for UV to IR applications, making them ideal for metrology, laser scanning, laser material processing, and broadband optical systems.

Metal Optical Coatings

Pleiger Laseroptik uses a variety of high-quality materials for coating

Gold Coatings

Gold is the best material for all metallic coatings in the infrared range, but can only be used from a wavelength of 700 nanometers (nm). As a gold coating is soft, it scratches easily. For this reason, the gold coating should be provided with a dielectric coating.

Gold is a precious metal that does not tarnish and is therefore stable over the long term. A gold coating can therefore also be used without a protective layer, e.g. in FTIR spectroscopy. Areas of application for metallic coatings with gold are infrared mirrors (measurement technology), laser mirrors (low power applications) and protective coatings (corrosion protection).

Silver Coatings

Silver coatings have the highest reflection in the visible and infrared spectral range. However, due to silver's affinity for some parts of the air, this material tarnishes easily. A protective coating can significantly slow down this process, but not completely prevent it. Metallic coatings with the material silver are used for VIS / IR mirrors, which are used in measurement technology and astronomy. Silver coatings are also used in the manufacture of laser mirrors (low-power applications).
