Thulium fluoride has a high refractive index and good optical stability, and can be used for optical coating. Coating thulium fluoride thin film on the surface of optical components can adjust the reflectivity and transmittance of optical components, and is often used in optical instruments such as telescopes, microscopes, and cameras.
Thulium fluoride is used as a doping material in thulium-doped lasers to output 2um band lasers. This laser has high absorption rate and low heat-affected zone characteristics, and is particularly suitable for stainless steel cutting in industrial processing.
Thulium fluoride can be used as a magnetic additive to improve the properties of magnetic materials, such as magnetic permeability, coercivity, etc. In the fields of electronic devices, sensors, etc., there are strict requirements on the performance of magnetic materials.
Other applications: Thulium fluoride can also be used to prepare scintillators. In medical positron emission tomography (PET), scintillator material is one of the key components. Thulium fluoride scintillator may provide a new way to improve the resolution and sensitivity of PET imaging. In the nuclear industry, it can also be used as a neutron absorption material and radioactive waste treatment.
Q: Can you provide a small amount of thulium fluoride sample?A: We can provide about 10g of sample.
Q: How to transport the goods?A: We have sea, land and air transportation, but mainly sea transportation.
Q: What is the cutting accuracy of stainless steel using thulium-doped laser?A: Thulium-doped laser has high cutting accuracy, can achieve a smaller spot size, can finely cut stainless steel, and the cutting accuracy can reach micron level.
Q: What role does thulium fluoride magnetic sensor play in electronic equipment?A: It is used for hard disk head positioning to improve data reading and writing performance; it can also be integrated with other sensors to monitor parameters such as temperature, humidity, vibration, etc., to help optimize equipment performance and fault diagnosis.
