Dielectric Mirrors
Dielectric-coated mirrors are optically coated using dielectric coatings. Their coatings are very durable, making them easier to clean repeatedly and more resistant to laser damage. The spectral range of their operation can reach hundreds of nanometers, and the incident angle is usually between 0°-45°. This technology can minimize the loss of almost all optical systems and reduce the amount of stray light in the system, thereby optimizing the performance of the optical system.
CLZ Optical Co., Ltd.'s standard dielectric-coated mirrors use Fused Silica, an excellent substrate. Fused Silica is a synthetic amorphous silicon dioxide of extremely high purity. Its low coefficient of thermal expansion makes it an ideal material for high-precision mirrors. It also has better transmittance from the UV to the near-IR wavelength range than other glasses. In addition, this colorless quartz glass has a low inclusion content and high refractive index uniformity. As a result, these mirrors perform better under temperature fluctuations and are well-suited for dielectric mirror applications due to their high energy damage threshold.
