Where to Buy Infrared Optics

We deliver highly integrated, superior performing, infrared optical components leveraging our combination of technical skills, unique manufacturing competencies, and extensive metrology capabilities.

We bring together a set of capabilities which enables our customers to combine techniques, even on the same part. A unique, stand-out capability for G&H is our ability to manufacture complex shapes on lenses, such as step profiles or off-axis shapes.

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.

LightMachinery has extensive expertise in the manufacturing and testing of 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, IR polymers, magnesium fluoride, sapphire, silicon, zinc selenide, zinc sulfide and other infrared materials.

Alongside our optical components for the ultraviolet (UV) and visible spectral regions, we also offer a wide variety of IR optics as custom-made components or from our vast range of stock. Our IR range varies from near-infrared (NIR) (700 nm to 1.2 μm) and mid-wavelength infrared (MWIR) (3 to 5 μm) to far-infrared (FIR) (8 to 30 μm+).

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), germanium (Ge) for laser and optical instruments applications in the infrared wavelength range.

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.

NIL Technology provides a wide range of standard and custom made Diffractive Optical Elements (DOE), Micro Lens Arrays (MLA), and gratings for use in various optical systems in both visual and infrared applications.

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.

Dynasil offers a wide selection of infrared optics including HEAR & DLC and gold coatings, infrared windows and wire grid polarizers. Coatings can be applied to a variety of substrates like silicon (Si), germanium (Ge), zinc sulfide (ZnS), zinc selenide (ZnSe) and chalcogenides to achieve desired spectral characteristics
