Spectral Range 300-2500 nm; Standard and Custom Optical Coatings; Fully Automated E-beam Ion Beam Assisted Deposition (IAD) Technology; High Power Handling; Hard Abrasion Resistant Dielectric Coatings

Optical thin film coatings are used to change the spectral transmission and reflection behavior of optical surfaces to produce optical components with desirable spectral properties. Nowadays, almost all optical devices have some optical coating applied onto their optical surfaces.

OZ Optics uses all-dielectric coating materials and designs that insure virtually no absorption, low loss and no scattering. OZ Optics specializes in coating high power optical components that are used in a variety of applications and industries, using state-of-the-art fully automated electron beam ion assisted technology for manufacturing.

Below is a brief description of the coatings available from OZ Optics. we produce. custom designs and runs can also be produced per customer request – contact AMS Technologies for details.

Antireflection (AR) Coatings – Laser Line, Wide Band, Dual Band Coatings:
Antireflection (AR) coatings are required to increase light throughput, reduce back reflections and minimize stray light in an optical system over a desired spectral range. Optical elements including fiber tips, parallel plates, lenses, and prisms are all regularly antireflection coated. A large variety of antireflection coating designs are regularly used and available. These include AR coatings for:

  • Major laser wavelengths,
  • Dual-band (DBAR) antireflection coatings,
  • Broadband (BBAR) antireflection coatings
  • Custom designs for user-specified spectral regions.

Plate Beamsplitters, Tap Coatings, Partial Reflectors:
Beamsplitters are used to split reflected and transmitted light of a given spectral range at a specific ratio and predefined angle of incidence (usually 45 degrees). Examples include 50/50, 70/30, and 90/10 transmission/reflection ratios. This also includes control of the polarization states of the reflected and transmitted beams.
Tap coatings are used to transmit light but to reflect (tap off) a small portion of light at usually small angles of incidence (e.g 1.8 degrees). 99/1 and 95/5 are common ratios. These are used in a variety of optical systems to measure and control the amount of light that is exiting the optical device (power monitoring).

Longwave and Shortwave Pass Filters (Dichroics):
Longwave and shortwave pass (also called edge filters, dichroic filters) transmit and reflect certain parts of the spectral range. These filters are designed and made for a predetermined angle of incidence (such as 0 or 45 degrees) or range of incident angles (eg. 0-20, 35-50 degrees), depending on the optical design of the device used. They are used for a variety of applications that require beam combining and separation based on wavelength.
One example would be wavelength division multiplexers (WDMs). These devices are used to combine different incoming wavelengths into a single beam. For example, one could combine 532 nm and 633 nm wavelengths into one beam.

Laser Line High Reflectors:
High reflector mirrors reflect light over a predefined spectral range. Also, partial reflecting mirrors are made where a fixed portion of the light is transmitted. OZ Optics focuses on coating dielectric high reflectors on custom substrates or on fiber tips for a variety of applications. These coatings feature low absorbance, and high power handling. Typical reflectance is R> 99-99.9 %.

Custom Optical Coatings:
OZ Optics does custom coatings for a variety of applications. Please contact AMS Technologies with your request – we will send you a proposed design (spectral performance) and quote.
