Due to its wide transmission range and high hardness, calcium fluoride is an ideal material for manufacturing window sheets. In the ultraviolet, visible, and infrared wavelengths, calcium fluoride window sheets show good transmission properties and stability, making them ideal components for various optical instruments and equipment. These instruments and equipment are widely used in scientific research, industry, medical, and military fields.

-Thermal Imaging

In the field of thermal imaging, calcium fluoride window sheets also show their unique advantages. Due to their high transmittance in the desired wavelength range, thermal imaging systems are able to more accurately capture thermal radiation information from the target object for temperature measurement and thermal field analysis.

-Free-space laser-related applications

Free space laser technology is a new type of optical communication and sensing technology with high speed, long distance, and large capacity transmission capability. Calcium fluoride window sheets play a key role in free-space laser-related applications, providing a stable and reliable channel for laser transmission.

Calcium fluoride window sheets are widely used in the field of optics, and their unique physical and chemical properties make them ideal for spectral analysis, laser systems, window materials, thermal imaging, and free-space laser-related applications. With the continuous development of science and technology, the application prospect of calcium fluoride window sheets will be broader, bringing more convenience and progress to human production and life.


Single crystal calcium fluoride for infrared is a common transparent material with a wide range of infrared applications. Its unique properties make it one of the indispensable materials in the field of infrared technology.

First of all, a monocrystalline calcium fluoride window sheet for infrared has good light transmittance. Calcium fluoride is a colorless crystalline material with high transmittance for infrared radiation. In the infrared spectral range, the transmittance of calcium fluoride window sheets is more than 80%, which can effectively transmit infrared light signals, making it an important part of infrared sensors, infrared thermal cameras, and other equipment.

Secondly, it has excellent thermal stability performance. Under high-temperature environment, the calcium fluoride window sheet can maintain good structural stability and optical performance. This makes it possible to perform infrared measurement and monitoring under high-temperature conditions, such as temperature distribution monitoring in high-temperature furnaces, infrared imaging of high-temperature processes, and so on.

In addition, it is corrosion and chemical-resistant. It has excellent stability to a wide range of chemicals and can be used for a long time in corrosive environments such as acids and alkalis. This property enables calcium fluoride window sheets to be used in infrared analysis, reaction monitoring, and other tasks in the chemical field.

In addition, it has good mechanical strength and hardness. Its high hardness is not easy to be scratched and abraded, and it can keep clear and transparent in harsh environments. This makes the calcium fluoride window sheet able to meet the needs of some special working conditions, such as aerospace, optical communication, and other fields.


In summary, monocrystalline calcium fluoride window sheet for infrared has a wide range of applications in the infrared field. Its excellent light transmittance, thermal stability, corrosion resistance, and mechanical strength make it a very important material in the field of infrared technology. In infrared sensors, infrared cameras, infrared analyzers, and other equipment, calcium fluoride window sheet is widely used. It can play an important role in various fields to help people carry out infrared measurement, infrared monitoring, infrared analysis, and other work. With the continuous development of infrared technology and the expansion of applications, the value and significance of calcium fluoride window sheets will be more and more prominent.
