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.

ICC can provide mirrors with various substrate materials, such as BK7, single crystal silicon, quartz, sapphire, calcium fluoride, zinc selenide, metallic copper, alloy aluminum, etc. The products can be flat mirrors, spherical mirrors and beam splitters. The coating can be UV-enhanced aluminum, protective silver, enhanced gold, and dielectric mirrors. These products are widely used in optical instruments, laser systems, medical imaging, and analysis equipment.

The laser lenses provided by Intrinsic Crystal are mainly used for scanning, illumination, imaging, or cutting systems. They can be used for laser shaping, beam expanders, beam combiners, field lenses, galvanometer mirrors, and beam splitters. The available optical materials are quartz, BK7 glass, ZnSe, calcium fluoride, monocrystalline silicon, sapphire, ZK7 and others. Other products are protective windows, plano-convex lenses, dielectric mirrors, wedge metal mirrors, prisms, etc. The typical wavebands are 355 nm, 532 nm, 1064 nm, 2940 nm and 10.6 μm, the sizes are from 0.5" to 4".

Intrinsic Crystal is engaged in material growth, optical lens processing, and optical coating services. All processes are completed in its own factory, and there are complete testing equipment, such as ZYGO, ATM, spectrophotometer (190 nm – 25 μm), and a 5-second goniometer.

We can not only ensure the stability of the lens quality, but also provide the best price. We are your partner from R & D to mass production.

ICC has the largest fluoride crystal production capacity and the strongest processing capacity supplier in China, with an annual output of more than 50 tons of calcium fluoride crystals. The intrinsic crystal of CaF₂ crystal has strict classification, including infrared grade, ultraviolet grade, excimer grade calcium fluoride. Among them, the excimer grade calcium fluoride crystal material has low stress, high internal uniformity, no coloring, no fluorescence and other high quality properties.

The intrinsic CaF₂ crystals can be used in microscope lenses, astronomical reversion system, ultraviolet lighting and imaging system, 2D/3D machine vision system, infrared imaging and temperature measurement, high-energy laser field and all kinds of spectral analysis instruments. The excimer grade CaF₂ material is widely used in laser imaging and laser lighting fields.

The crystal structure can be polycrystalline or single crystal (any direction). We can offer UV-grade material for 0.2–7.0 μm, IR-grade for 4–7.0 μm and excimer-grade for 193 nm, 248 nm and 355 nm.

Custom products can be made for low stress, low delay, special crystal directions, and doped crystals.

ICC currently has six different coating machines, including one for diamond-like carbon (DLC) and two for broadband anti-reflection coatings. We mainly produce infrared antireflection coatings, infrared filters, and diamond-like carbon coatings, providing customers with various coating services and products.

Our DCL coatings are made with advanced technology to meet US military standards and reach excellent surface finish.

Intrinsic Crystal Technology offers various types of optical crystal materials such as LiF, ZnSe, sapphire, germanium, silicon and CaF₂.

ICC supply UV-VIS-IR windows made in CaF₂, BaF₂, MgF₂, Si, Ge, ZnSe, BK7, UVFS, sapphire, pyrex, borofloat, etc. These material can be coated or uncoated with sizes from 3 mm to 350 mm.

We supply various kinds of prisms, including wedge prisms, corner cube prisms, dove prisms, penta prisms and right angle prisms.

ICC have a very strong ability for producing ultraviolet optical windows. We apply three polishing techniques: pitch polishing, double side polishing and contact polishing to supply window sizes from 1.2 mm to 350 mm with a thickness from 0.12 mm to 60 mm. The shape can be round, square, drilled, step, or customized based on our CNC machines. (We can use a CAD drawing to work with customized shape windows.)

ICC windows can reach high level precision like s/d 10–5; flatness λ/10 at 633 nm; parallelism better than 5 min; bevel 0.1–0.25 mm; Ra < 1 nm based on testing devices of ZyGO, AFM, 15-sec gonimeter, and 2D imaging system.
