It is resistant to UV radiation, and features a high level of optical clarity and a low refractive index. The transmission efficiency rate is up to 95%, and the light pipe has a wide range of temperature and environmental stability. It has a length of 250mm and a core diameter of 125µm.

Application Fields of PLPQ3-125-FF

PLPQ3-125-FF is mainly used in automotive, medical, and industrial applications. In the automotive sector, the light pipe is used to deliver light from interior and exterior LED lamps, as well as to provide illumination for safety systems, including reversing cameras, headlights, signals, and speedometers. In the medical industry, the light pipe is used in MRI machines, surgical microscopes, and laparoscopes. It is also used in various industrial sectors, such as aerospace, heating and cooling, chemical and process engineering, telecommunications, and power applications.

Working Principle of PLPQ3-125-FF

The working principle of PLPQ3-125-FF is based on the total internal reflection (TIR). TIR is the phenomenon wherein the light is reflected at the boundary between two media when the angle of incidence is larger than the critical angle. The light pipe is designed with a core that is surrounded by an outer cover layer. The light is incident on the inner core at an angle that is greater than the critical angle, which is determined by the refractive index of the core material. The light is then totally reflected off the inner core, as long as the angle of incidence is greater than the critical angle. The outer cover layer also functions to reduce the angle of incidence and the losses due to scattering and absorption. The light is then transmitted along the length of the light pipe. This process is known as TIR optical coupling.

Conclusion

PLPQ3-125-FF is an extremely versatile and reliable fiber-optic light pipe that is widely used in many industries. It has many advantages, such as high optical clarity, high transmission efficiency, wide temperature stability, and UV radiation resistance. Its working principle is based on total internal reflection, and its use is increasing in sectors such as automotive, medical, industrial, and aerospace. This makes it an ideal choice for many applications.
