Where to Buy Dielectric Coatings

UltraFast Innovations (UFI®) can design and fabricate various types of dielectric coatings, in particular those featuring a broad reflection bandwidth and controlled chromatic dispersion properties. Such coatings are applied to various optical components and can also be applied to components sent to us.

Focuslight Technologies produces dielectric coatings with IAD deposition. That includes anti-reflection coatings (from deep UV to the infrared), high reflectors, beam splitters and filters.

We offer a range of dielectric coatings for optimum reflectivity. Available for a variety of components including beamsplitters, front-surface mirrors and rod and cone mirrors, to name but a few, our dielectric options include visible, near-infrared (NIR), infrared (IR) (2000 nm +) and large parts (1000 mm).

Avantier is capable of providing a comprehensive range of dielectric coatings, including anti-reflective, high reflective, and partial reflective coatings. Our coating portfolio encompasses a diverse range of coatings, ranging from a single layer of anti-reflective coating to intricate multi-layer dielectric stacks. Our dielectric coatings come in various types such as BBAR, V-coatings, dual wavelength coatings, as well as sharp cut-on and cut-off filters.

LASEROPTIK can fabricate dielectric coatings with a range of methods including electron beam evaporation (EBE), ion assisted deposition (IAD), ion plating (IP), magnetron sputtering (MS) and ion beam sputtering (IBS). With our high precision machinery, we can produce accurate coatings for a wide range of wavelengths, substrate materials and applications. In addition to a large selection of from-stock optics, we offer coatings with refined custom designs.

We offer dielectric laser mirrors for fixed, narrowband or broadband applications covering the UV, VIS and IR spectral regions. A wide range of round, elliptical or custom shapes as well as plano, spherical, cylindrical surface mirrors and substrates are available. Custom anti-reflection, high-reflection, partial-reflection dielectric coatings can be designed by qualified optical engineers and deposited in EKSMA Optics' advanced ion beam sputtered (IBS) coating facility.

IRD is poised to serve all your coating needs, be it for the ultraviolet (UV), visible, or infrared (IR) spectral region. We have the ability to offer quick-turn basic coatings in-house. Our complete offerings run from basic MgF₂ coatings to the incredibly intricate multiple-stack coatings, metallization and more. IRD offers HLDT AR and mirror coatings, ultra-high reflective mirror coatings, beam splitters, notch, BBAR and many more.

OPTOMAN concentrates on a single manufacturing technology – ion beam sputtering (IBS). We manufacture custom dielectric thin films for the 200 – 5000 nm spectral range. We are ready to develop cost effective yet advanced, high accuracy and repeatability thin film coatings optimized for your application. Our product range includes: laser line and broadband mirrors HR > 99.9%, R < 0.1% anti-reflective coatings, and thin-film polarizers with extinction ratio reaching 10000:1.

Shanghai Optics can provide all types of anti-reflective, high reflective, and partial reflective coatings. We produce a wide variety of coatings from a single layer of anti-reflective coating to complex multi-layer dielectric stacks. Types of dielectric coatings are BBAR, V-coatings, dual wavelength coatings, and sharp cut-on and cut-off filters.

Perkins Precision Developments (PPD) manufactures custom IBS coatings for laser mirrors, beam splitters, polarizers and other precision optical components for wavelengths from 350 nm to 3 μm. PPD utilizes Ion Beam Sputtering coating technology because it is ideal for complex spectral designs, high power Nd:YAG and fiber lasers and applications where it is critical to minimize losses from absorption and/or scatter. IBS thin films have densely packed micro-structures resulting in stable, easy to clean optics that are insensitive to environmental changes such as heat, humidity and pressure. Our coatings may exhibit damage thresholds of >20 J/cm² or sometimes even >60 J/cm² at 1064 nm.

Common coating types include high power high reflectors (HR), multi wavelength reflectors, low-loss anti-reflection (AR), dual-band anti-reflection (DBAR), dichroic and trichroic beam splitters, output couplers, low phase shift mirrors, dispersion controlled mirrors, polarizers and non-polarizing laser-line beam splitters.
