Beamsplitters can be used for dividing light beam. They have two different coatings by metal and dielectric materials.

  Ultra Broadband
  Cube Beamsplitters
  Plate Beamsplitters

Windows are used for a transparent barrier so that a beam of light can be transmitted between two phases in the different environments.

  Windows BK7
  Brewster Window
  Window Quartz
  Windows Fused Silica

Waveplates (retardation plates or phase shifters) are made from materials which exhibit birefringence. The velocities of the extraordinary and ordinary rays through the birefringent materials vary inversely with their refractive indices.

  Low Order Waveplates
  Zero order waveplates
  True Zero Order Waveplates
  Dual Wavelengths Waveplate

As the hardest oxide crystal Sapphire crystal is the most basic monocrystal form of Al2O3. It has many good physical and chemical properties of high strength high hardness high temperature resistance scratch-resistance anticorrosion and good performances of light transmission and electrical insulation etc. So it can be widely used in such fields with different strict requirements as national defense scientific research and civilian industry etc.
