產品特色

These coatings are designed to increase the transmission over a broad spectrum

Coatings are provided by Ion Beam Sputtering (IBS) or Electron beam evaporation with/without Ion assistance coating techniques

Dual Anti-Reflection Coatings in the range 0.19-10.6 µm are available

Dual AR coated windows designed to reduce the reflectivity of a component to near-zero for two certain wavelengths. Usually these windows are used in multi-frequency laser output systems (e.g. frequency doubling). This type of coating provides very high transmission at two different wavelength. Typical wavelengths and reflection curves of an AR coating suitable for the standard laser system output at 1064 nm and 532 nm are shown below.
