IR Optics
Sapphire
Sapphire (Al2O3) crystal is a kind of excellent multifunctional material. It has high surface hardness, high temperature resistance, good thermal conductivity, UV-IR transmittance and good chemical stability. It is used in ultraviolet (UV) and visible wavelengths beginning around 200nm and also performs well in IR to around 5µm. sapphire offer exceptional optical and mechanical properties, making them a popular choice for infrared applications that require high performance, durability, and reliability.
MOK Optics capability:
We produce sapphire windows, sapphire lightguides, sapphire tubes, sapphire domes and various special shapes sapphire optics. They are widely used for IPL bueaty machine, IR laser system, high temperature IR window, protection window etc. We are able to produce the ultrathin sapphire windows with 0.15mm thickness. AR coating is available
MgF2
Magnesium Fluoride (MgF2) is a synthetic crystalline substrate, transparent over a wide range of wavelengths (120 nm – 6.0 µm), magnesium fluoride is well suited for applications ranging from the UV to the IR. MgF2 is very rugged and durable, making it useful in high-stress environments. It is commonly used in machine vision, microscopy, and industrial applications.
MOK Optics Capability:
We provide UV grade MgF2 windows, Max Diameter 170mm, Oriention:<001>,<100>,<110>.
CaF2
Calcium Fluoride (CaF2) is transparent from the UV to the IR (180 nm – 8.0 µm). and is mechanically and environmentally stable. CaF2 is ideal for any demanding applications where its high damage threshold, low fluorescence, and high homogeneity are beneficial. It is popular in excimer laser applications and frequently used in spectroscopy and cooled thermal imaging.
MOK Optics capability:
We provide excimer grade CaF2, vacuum VUV grade CaF2, UV grade CaF2, IR polycrystal CaF2, Max Diamter 350mm, Oriention:<100>,<110>,<111>
Silicon
Si lenses and windows are an ideal choice for applications using wavelengths in the near-IR range and parts of the mid-IR range. Silicon offers high thermal conductivity and low density, making it suitable for laser mirrors. However, since silicon has a strong absorption band at 9 µm, it is not suitable for use with CO2 laser transmission applications. Silicon optics are also particularly well suited for imaging, biomedical, and military applications. Silicon has a transmission range from 1.2 µm to 8.0 µm.
MOK Optics capability:
We produce various of Silicon windows, Silicon lenses with AR coating, DLC coating.
Zinc Selenide (ZnSe)
Zinc Selenide has wide transmission band and low absorption in the red portion of the visible spectrum, it is commonly used in optical systems that combine CO2 lasers (operating at a wavelength of 10.6 µ m). ZnSe is transparent in the wavelength range of 0.6 – 16 µ m, making it highly suitable for infrared applications. It is also commonly used in thermal imaging systems. Unlike germanium and silicon, ZnSe can also transmit some visible light, making it suitable for visual optical collimation. However, it is very soft and prone to scratches.
MOK Optics produce various of laser grade ZnSe lenses, windows with AR coating, Welcome to contact us for more details.
Zinc Sulfide (ZnS)
Zinc Sulfide has low absorption and scatter properties over its broad transmission range of 0.4 – 12μm, it is a chemical vapor deposited material which is commonly used in thermal imaging. With its excellent transmission properties in the visible and infrared, ZnS is the material of choice for systems that have both visible and mid-wave or long-wave infrared sensors. ZnS is slightly harder and has more chemically resistant than ZnSe. So it can be used in the applications that require high mechanical strength and environmental durability.
MOK Optics produce various of Multi-spectral grade ZnS（Cleartran）lenses, windows with AR coating, Welcome to contact us for more details.
