3.0μm to 13.5μm Diamond-Like Carbon Coatings Infrared Silicon Windows
Coligh manufactures infrared silicon DLC window protection thin films with a transmittance of more than 55% in the range of 3μm-13μm. They are extremely durable and provide good window transmittance and protection for infrared sensors.
3.0μm to 13.5μm Diamond-Like Carbon Coatings Optical Silicon Windows
Coligh’s 3.0μm-13.5μm diamond-like carbon coating optical silicon windows are high-performance window protectors designed specifically for infrared optical systems. We coat the silicon surface with a diamond-like carbon film, which is extremely wear- and scratch-resistant while ensuring a transmittance greater than or equal to 55% within this wavelength range. The properties of silicon as a substrate ensure the mechanical strength of the window, making it a suitable alternative to germanium windows in China, where the sale of germanium windows is currently prohibited. Infrared windows in this wavelength range are primarily used in mid-infrared and long-wave infrared thermal imaging, infrared detection, and laser applications.

3.0μm to 13.5μm Diamond-Like Carbon Coatings Infrared Silicon Windows Applications:
High-Power CO2 Laser Windows
In high-power CO2 lasers at 10.6μm wavelengths, laser welding and cutting are often fraught with smoke and metal spatter. The high-hardness DLC coating protects the laser, while the silicon material ensures high-temperature operating environments and protects the window from scratches.
Infrared Thermal Imagers
Infrared thermal imagers primarily operate in the mid-infrared and long-wave infrared. DHL-coated silicon windows protect the thermal imager’s infrared detector from contamination and scratches. Furthermore, the silicon window ensures the thermal imager remains operational even in extreme weather conditions.
Infrared Optical Sensors
In products such as gas analyzers, flame detectors, and temperature sensors, DLC silicon windows resist corrosion from various gases and resist impact from dust particles.
