Optical thin film coating Precision Photonics

Advantages of PPC's Ion-Beam-Sputtered (IBS) Dielectric Thin Films
--------------------------------------------------------------------------------
Durable, dielectric thin films are easy to clean and chemically resistant
Dense, non-porous structure is insensitive to moisture
Low scatter and absorption losses result in high-damage thresholds
Repeatable, highly controlled process for precise layer control
--------------------------------------------------------------------------------
At PPC, we use ion-beam sputtering (IBS) technology because IBS is a repeatable and controllable process that results in dense, durable, high-damage-threshold thin films. Since the materials are directly sputtered onto the substrate, the process can be precisely controlled and easily automated so that films can be deposited with extremely high accuracy and repeatability.

Unlike conventional evaporative and ion-assisted films that have porous microstructures, IBS films have extremely densely packed structures that make them impervious to water vapor, resulting in an insensitivity to changes in heat and humidity, even in a vacuum environment.

Types of coatings that PPC does every day on standard or customer-supplied substrates:
High reflectors
Anti-reflection (ARs)
Beamsplitters
Polarizers
Partial reflectors
Dichroic mirrors
Non-polarizers
Low dispersion
Broadband dielectric
