Definition
A long wave pass filter is transparent in a specific wavelength range, with the long wave direction being cut off to isolate the short wave direction.
Characteristic
It has high transmittance, low loss, and good spectral transmission characteristics, suitable for spectral transmission in various frequency bands. In addition, it also has the characteristics of acid and alkali resistance, chemical stability, small thermal expansion coefficient, high mechanical strength, and long service life.
Spectral transmission range
The main wavelength range transmitted is visible light and near-infrared light, which has the function of shielding infrared radiation.
Application area
In the field of optics, it is used to manufacture special optical glass, fiber sensitizers, laser crystals, and infrared detectors.
Electronics industry: can be used to produce ultra-high frequency dielectric film, resistor capacitor, ceramic filters and capacitors, as well as microwave resonant cavity filters, etc.
Biomedical field: used for manufacturing artificial corneas and scaffold materials for bioengineering.
Other applications: infrared detection, wireless communication, air quality detection, etc.
