Partial reflecting mirrors (PR)
Model: PR
品牌:Standa

產品特色Features

Efficient beam splitting as well as output coupling in high power laser cavities

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

Various wavelengths and Reflectivity values are available

Any other our standard substrate can be coated with this type of coatings

Partial reflecting mirrors (PR) provide required percentage reflection/transmission at a specific angle of incidence for both single and broad band wavelenghts These coatings serves usually for the efficient beam splitting as well as output coupling in high power laser cavities.
