Mirror is a smooth,highly polished surface covered a thin coating.Mirror is usually a thin coating of metal or dielectrics.
VY Optics designs and manufactures a great choice of various high and partially reflecting mirrors for the spectral range:UV,visible,near infrared,and infrared regions.Metallic coatings are more broadband while dielectric coatings are more efficient.
Selecting the proper mirror for your application requires making a number of choices.A few of the many considerations include:Reflectivity,Laser Damage Resistance, Coating Durability,Thermal Expansion of the substrate,Wavefront Distortion,Scattered Light,and certainly Cost.
