Optical Coatings

Indium Tin Oxide (ITO) combines optical transmission with conductivity for applications including EMI shielding, transparent heaters, displays, and sensors. Index-Matched ITO (IMITO) is available for applications requiring improved transmission and reduced reflection when the conductive coating interfaces with liquid crystal, optical cement, index-matching fluids, or other materials.

Sheet resistance and optical performance can be tailored to meet application requirements.

HEF Photonics offers standard and custom optical filters designed to selectively transmit, reflect, or block specific wavelengths or spectral bands. Filter solutions support applications including imaging, sensing, illumination, fluorescence, color separation, night vision, and UV/IR management.

Available solutions include dichroic and color filters, bandpass and notch filters, longwave and shortwave pass filters, NVIS filters, IR and covert filters, and UV blocking or transmitting filters.

HEF Photonics offers metallic and dielectric mirror coatings for applications requiring high or broadband reflection across selected UV, visible, and infrared spectral regions. Available solutions include aluminum, silver, gold, and other metallic coatings as well as custom dielectric designs for specific wavelength ranges and performance requirements.

Semi-transparent and thin or ultra-thin mirror solutions are also available for specialized applications.

Functional and specialty coatings add surface properties or environmental durability to glass and optical components. Available solutions include oleophobic, hydrophobic, anti-fingerprint, anti-abrasion, autoclavable, and other application-specific coatings for demanding use environments.
