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.

Processes within Optics

E-Beam & Thermal Evaporation
Denton systems support e-beam evaporation for high-end metal oxides, metals, conductive oxides and astronomical films. Denton provides highly densified, ultra-transparent films at world-class standards for UV, IR and visible applications.

Optical sputtering applications include digital Rugate development and ultra-thin filter designs.

Denton Vacuum provides thin film technology for biocompatible PVD coatings—films that are very hard, very adhesive, wear-resistant, inert, low friction and designed not to react with bone, tissue or bodily fluids.  These film characteristics make these films extremely well suited for use on medical devices, components and surgical instruments.  Additionally, a hydrophilic lubricious coating can help improve patient comfort when applied to such medical devices as catheters, guidewires and other short-term implanted devices.

Other medical coating application provide such benefits as edge retention (surgical instruments stay sharp), reduced galling (stainless parts don’t interact with one another), competitive product differentiation [dark gold (TiN), silver-gold (ZrN) and black (AlTiN, also known as black TiN)]. Coatings applied to medical devices help reduce friction that may minimize irritation and inflammation, formation of scar tissue surrounding implanted devices or encourage the growth of tissues to help the healing process.

Denton Vacuum’s broad range of thin film technologies and over 50 years of experience provide the makers of medical instruments, implants and devices innovation solutions required to fabricate active and passive components, reduce friction, extend use, color code, and enhance biocompatibility.
