Where to Buy Infrared Optics

Vortex Optical Coatings design and manufacture infrared filters for the most demanding and complex applications. We cover the band from 1–6 microns.

At Shanghai Optics we design and manufacture a wide variety of custom optical IR components. Our state of the art equipment allows us to achieve unparalleled precision and surface quality, and every piece we manufacture is subject to stringent quality controls.

We offer a wide range of IR substrates, including Ge, Si, ZnSe, ZnS, ZnS , CaF₂, BaF₂ and GaAs. Our lenses and windows are available with multiple anti-reflection coating options that can increase durability and improve performance.

IRD Ceramics manufactures precision infrared optical components which are essential to infrared cameras and sensors used by homeland security, border patrol, defense and security companies. We perform all fabrication in house, allowing us to produce low-cost IR mirrors, lenses and windows for commercial applications as well as customized lenses to meet the exact demands of defense and security companies. IRD Ceramics works with sapphire, silicon, chalcogenides, germanium, BaF₂, CaF₂, zinc selenide and more.

OPTOMAN employs IBS technology to manufacture dispersive mirrors made for mid-IR (2 – 6 µm). Broadband dispersive and low GDD mirrors for mid-IR range can reduce or even completely eliminate the need to use combinations of various bulk materials to compensate dispersion.

Custom mid-IR optics can be designed for spectral range 1 – 5 µm, using standard or CaF₂, MgF₂, YAG, sapphire or silicon substrates.

Iridian’s SWIR, MWIR and LWIR bandpass filters are designed to optimize detection of spectral emission lines. These filters are deposited using energetic sputtering, which makes them very hard and durable.

The resulting filters also have exceptionally high transmittance levels and blocking from the visible to the LWIR. Iridian has off-the-shelf band pass filters for many of the wavelengths commonly used for gas detection.

Available gas lines include H₂O, CH₄, CO₂, CO, N₂O and O₃.

Filters for other wavelengths can also be supplied.

Ecoptik manufactures precision infrared optical devices based on germanium, silicon, zinc selenide, zinc sulfide and other materials. Customized high-precision and complex optical devices, including short-wave infrared optical devices of many kinds can be made. Feel free to contact us!

EKSMA Optics has substrates and finished optical components – windows, lenses and mirrors made from lithium fluoride (LiF), calcium fluoride (CaF₂), barium fluoride (BaF₂), sapphire (Al₂O₃), zinc selenide (ZnSe) and germanium (Ge) for laser and optical instruments applications in the infrared wavelength range.

Shalom EO offers a wide range of infrared optics – not only singlet IR optical lenses, IR optical windows and IR domes, but also lens modules designed for MWIR (3-5 μm) and LWIR (8-12 μm) thermal imaging cameras. A variety of specific infrared optical materials are available: germanium, zinc selenide (ZnSe), zinc sulfide (ZnS), chalcogenide glass, silicon, sapphire and fluoride (CaF₂, BaF₂, MgF₂ and LiF). Our fabrication techniques include conventional polishing and diamond turning. Moreover, multiple types of modules with flat, spherical and aspherical optical surfaces are optional for different requirements. Referring to the thermal imaging lenses, Hangzhou Shalom EO offers standard lenses and hundreds of custom free-designed lens modules (e.g. athermalized lenses, fisheye lenses, single FOV, dual FOV, zoom lenses).

Further, our infrared windows can be used at 0.75 μm to 20 μm and our infrared lenses are suitable in a wide spectral range from 700 nm to 20000 nm. Infrared domes are suitable for 3 μm to 12 μm. AR coating options include broadband anti-reflection coatings (BBAR), long-pass anti-reflection coatings and hard diamond-like carbon (DLC) coating for application in harsh environments.

Intrinsic Crystal Technology is the biggest fluoride crystal material and optics supplier in China. We supply CaF₂, BaF₂, MgF₂, LiF material covering the VUV to IR spectrum. We can also deliver cut blanks, polished discs, drilled parts, spherical lenses, prisms and coated mirrors in very large quantity with best price. Intrinsic also grows silicon material including mirrors in optical grade and supplies optics like mirrors, AR-coated lenses and ATR prisms. We are also good at ZnSe/ZnS/Ge IR material optics.

Knight Optical can offer a variety of stock and custom infrared optics, such as lenses, windows, prisms and filters. We can provide these in a wide range of different materials including germanium, silicon, zinc selenide, calcium fluoride, sapphire, magnesium fluoride, zinc sulphide. Our custom infrared optics include aspheric lenses, filters working in the IR wavelengths, and coatings optimised for the different thermal wavebands, as well as diamond-like carbon (DLC) coatings for extra durability of a surface.

LightMachinery has extensive expertise in the manufacturing and testing of infrared optics based on zinc selenide, zinc sulfide and germanium optics for CO₂ lasers, e.g. in the form of mirrors, lenses and rhomb retarders. In addition, we have a thorough understanding of the importance of high damage threshold coatings for our laser customers.

Edmund Optics offers a wide range of infrared optics, using materials like aluminum, calcium fluoride, fused silica, germanium, magnesium fluoride, sapphire, silicon, zinc selenide, zinc sulfide and other infrared materials.

UltraFast Innovations (UFI) offers various kinds of broadband infrared mirrors for use in ultrafast laser systems. For example, we have mirrors for thulium- and holmium-based systems operating in the 2-μm spectral region, Cr:ZnS systems around 2.4 μm and Cr:ZnSe for 3.2 μm. Such mirrors can be provided with precise control of chromatic dispersion.
