Where to Buy Optical Windows

Edmund Optics’ optical windows are offered in a variety of substrates, such as germanium (Ge), silicon (Si), N-BK7, UV fused silica, zinc selenide (ZnSe), and potassium bromide (KBr). Multiple anti-reflection coating options are available for the ultraviolet (UV), visible, or Infrared (IR).

We provide optical windows down to λ/20 polishing, from 1 mm to 0.5 m diameter. All optical materials available.

Ecoptik manufacturers different types of optical windows, including custom versions. We can make different geometrical shapes, use many different materials (including some for infrared optics), and apply different optical coatings.

EKSMA Optics has a wide selection of optical windows made from high quality fused silica, BK7, calcium fluoride, barium fluoride, magnesium fluoride, zinc selenide and other optical materials.

UM Optics supplies UV-VIS-IR optical windows made of CaF₂, BaF₂, MgF₂, LiF, Si, Ge, ZnSe, BK7, UVFS, sapphire and others. These windows can be coated or uncoated with sizes from 3 mm to 350 mm. UM Optics can provide fully customized windows including round windows, rectangular windows, drilled windows and wedge windows to suit your application and with a variety of substrates available.

IRD glass manufactures many types of optical windows – ultraviolet windows, visible windows, infrared windows, and debris shields from .100″ to 16″ in height and in thicknesses of .008″ to 4″ using a wide spectrum of materials, including nBK-7, B270, borosilicate glass, F-5, fused silica, fused quartz, high-index glass, sapphire, silicon and other IR materials.

Knight Optical offers a range of stock optical windows including standard windows manufactured from BK7, B270, borosilicate, UVFS, Gorilla Glass, and plastic. We also have UV and IR materials available including barium fluoride, calcium fluoride, magnesium fluoride, germanium, zinc selenide, sapphire, silicon, and potassium bromide. Our optical domes are also a popular component, with stock and custom options available. Knight Optical can provide fully custom windows including the addition of coatings to suit your application and with a variety of substrates available.

Shalom EO offers a vast variety of optical windows:

• BK7 λ/4 windows
• BK7 λ/10 windows
• UVFS λ/4 windows
• UVFS λ/10 windows
• precise thin BK7/UVFS windows

Infrared optical windows made from BaF₂, CaF₂, germanium, silicon, zinc selenide (ZnSe) and sapphire are also accessible. Both off-the-shelf and customized products are available.

Artifex Engineering offers custom optical windows in almost any shape and design, including cut-outs and drillings. A wide range of optical substrates are available including N-BK7, fused silica, sapphire, Ge, ZnSe and more. AR coatings are generally applied to both surfaces of a window. In addition, Artifex offers custom coatings such as diamond-like carbon (DLC) coatings for the infrared (germanium, silicon). Visit our product page for more information. We look forward to your inquiry.

Perkins Precision Developments (PPD) manufactures multi-layer dielectric thin film coated laser windows and precision optical wedges in addition to custom uncoated substrates. Because we utilize Ion Beam Sputtering (IBS) coating technology, our AR coated parallel windows and wedge pairs are both durable and easy to clean. In addition, they exhibit low losses due to absorption and scatter, as well as high damage thresholds, making them ideal for both intra-cavity or extra-cavity laser applications.

Plane parallel windows, Brewster windows and matched wedge pairs are available in a variety of shapes and sizes from 2 mm to > 8” in diameter and with parallelism errors as low as 1 arcsecond. PPD manufactures precision plano substrates in a wide range of materials including fused silica, fused quartz, infrasil, N-BK7, YAG, silicon, SF11 and other high index glasses.

Custom low-loss anti-reflection (AR) coatings with reflectivity less than 0.1% per surface can also be deposited on customer supplied substrates up to 4 inches in diameter. Click here to see recent LDT data for an AR coating at 1064 nm.

OPTOMAN optical windows with IBS coatings are optimized to have excellent spectral performance, high damage threshold, temperature and humidity independent performance, and a negligible fatigue effect. OPTOMAN can coat very basic round and rectangular windows as well as wedges and prisms with extremely complex shapes. Sputtered anti-reflective coatings feature reflectance per surface down to R < 0.01%.

Laser viewing windows made of polymer or glass with defined laser protection specifications are available in stock and custom-cut sizes. Laser safe acrylic viewing windows are durable, scratch-resistant and have excellent optical clarity. These are available in stock sizes or custom-made for large viewing ports or small instrument viewing ports. Laser protective filter glass windows are superior for infrared, ultraviolet and extreme environmental conditions.

Laserton offers optical windows made of BK7 glass, fused silica or calcium flouride. They will as debris shields, for example.

Our optical windows are designed to minimize both reflection and absorption while maximizing transmission over a target wavelength range. When choosing an optical window, you will have to keep in mind optical surface specifications, material transmission properties, and the mechanical properties required by your application.

Shanghai Optics Inc state of the art factory is able to manufacture both large optical windows and micro windows for nano-sized optical assemblies. A wide variety of optical substrates are available to choose from, and since production is carried on in-house our design team, will be able to match your exact specifications when carrying out your order.

We supply anti-reflection coated windows, 'make complete', for low and high volume applications.
