Denton Vacuum enables innovation.

Denton Vacuum products for the optics industry deliver stable, highly uniform films and superior optical performance using sputtering, e-beam evaporation, ion-beam assisted evaporation, and thermal evaporation processes. Denton systems support e-beam evaporation for high-end metal oxides, metals, conductive oxides and astronomical films as well as highly densified, ultra-transparent films at best-in-class standards for UV, IR and visible applications. Denton’s optical sputtering applications include digital Rugate development and ultra-thin filter designs.

Denton Vacuum provides an array of precision-designed and configured electron beam and ion-assisted electron beam deposition technologies to help you influence and control the reflectance, transmittance, absorbance and resistance in your optical applications.

From high performance Indium Tin Oxide (ITO) and Index-Matched Indium Tin Oxide (IMITO) to patterned optics Anti-Reflective (AR) and anti-glare glass coatings, Denton Vacuum provides expert systems for your applications in front and back surface mirrors, dichroic filters, band pass color filters, Anti-Reflective (AR), beam splitters, metal coatings, precision hot mirrors, cold mirrors, neutral density filters, and IR and UV filters.
