MOXTEK’s broadband wire-grid polarizers provide excellent polarization contrast and transmission at wide cone angles. These inorganic polarizers are extremely small and are designed to tolerate high temperatures. Moxtek wire-grids are made of high purity materials which provide great optical properties but are susceptible to damage from water and oils droplets. Moxtek has developed the HTS protective coating for applications that expose the polarizer to water or oil droplets. This hydrophobic coating protects the wire-grids from damage caused by extreme environmental conditions where moisture, oily contaminants, and heat exposure are expected..
