optical coating services

With electron beam and automated ion-assisted coating process technologies, PFG is able to offer an extensive range of thin film coatings – anti-reflective, broad-band AR, short and long wavepass filters, optical beam splitter, polarizers and high reflectors, both dielectric and enhanced metallic coatings. We offer multiple thin film optics and use FilmStar design and characterization software to create customized coatings. Multiple optimization techniques ensure the end products meet/exceed specifications for all our practical production of optical thin films projects. Customized programs allow us to analyze coating sensitivity, production yields, total coating thickness, the time required to produce the coating and to the estimated change in surface figure post-coat. We offer thin film optical lenses coating and thin film optical filter among many other optical thin films and coatings from materials to applications.

Optical Facility tour

We clean and inspect our optics in a class 1000 clean room and under laminar airflow hoods with particle counts typically less than 10 (of ½ micron or larger) and use other thin optic techniques to produce absolute pristine surfaces. Custom optical coatings manufacturers understand the criticality of surface roughness, surface cosmetics, cleaning methods and materials, and ambient conditions. We aim to ensure that our process coating film technology and execution satisfy the spectral, mechanical, environmental, and laser damage requirements of customer coatings.

PFG uses E-beam technology for many of our thin-film coatings because this method is typically faster and less expensive than the alternative application of thin-film coating methods on the multilayer optical coatings market. For thin-film coating optics at lower wavelengths, using E-beam technology allows PFG to produce optics with some of the highest laser damage certifications and longest lifetimes in the industry. However, we have ion-assisted deposition (IAD) which can achieve performance similar to ion beam sputtering (IBS), but at a more affordable cost.

Custom thin film coatings testings

For spectral optical thin film coating measurement from UV to NIR practical design and production of optical thin films, we use Lambda 9, Lambda 900, and Lambda 1050 Perkin Elmer spectrophotometers. For IR spectral measurements, thin film optical coating companies US use a Perkin Elmer 983. Coating charts and witness samples are routinely supplied.

We offer advanced thin film optical coatings evaluation and design. Our thin film optical coatings materials indices dispersion and many products are coated with optic thins films.

We also have in house capabilities to test our coatings for:

  • Abrasion
  • Adhesion
  • Humidity
  • Salt Spray
  • Temperature

    light wave

    PFG has been producing industry leading AR coatings for 42 years. This long history gives us the expertise to apply AR coatings to the full array of optical glasses, crystals, and IR substrates. Known for their high durability, our AR coatings can survive all MIL-spec durability and environmental requirements. We can supply single-wavelength or broadband AR’s in the range 300nm through 5µm. Complimenting our spherical and flat polishing capabilities, we apply AR coatings to our in-house lenses, windows, and prisms. Our design and engineering team can also create a custom AR coating for any need on customer supplied substrates.
