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
Germanium
Germanium(Ge) has excellent transmission performance in the 2-16 micron band and opacity in the visible spectrum, This makes it an ideal choice for biomedical and thermal imaging system.They are often used as windows of the thermal imaging system and optical components. and can produce windows, lenses and prisms and other special shaped products according to customer requirements.
MOK Optics capability:
We produce various of germanium windows and germanium lenses upon customer requirements. The transmision of Ge is around 50% at 2-14μm, we typically need to make AR coating for Ge optics, we can also make DLC coating for Ge windows(Diamond like carbon coating).
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>
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>.
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.
