Optics - Light Pipes are integral components in many optical systems. The PLTR5-24MM-PR2 is one such component, providing an important link between the source of light (for example, a laser diode) and the device where the light needs to be transmitted (for example, a laser detector). In this article, we will discuss the application field and working principle of PLTR5-24MM-PR2.

Application Field

The PLTR5-24MM-PR2 is a fiber optic light pipe used for transmission of light within devices. This light pipe is ideal for applications where transmission of light over long distances is needed, such as within traffic lights or laser detectors. The device is made from polyimide coated plastic and is highly reliable with good flexibility and long life. The device can also be used in medical applications including endoscopy, where light needs to be transmitted from the endoscope to the viewing window or detector.

Working Principle

Light pipes, such as the PLTR5-24MM-PR2, rely on total internal reflection (TIR) to transfer light through the pipe. The core material, in this case polyimide coated plastic, acts as an optical waveguides, guiding light through the pipe without losing energy. When the light encounters the curved surface of the light pipe, it will move along the curved surface until it reaches a boundary surface where the refractive index of the material changes abruptly. At this point, the light will reflect at an angle equal to the angle of the incident light (TIR). This reflection will cause the light to bounce around the inside of the light pipe, allowing it to reach its destination without any energy loss.

The transmitted light is viewable through the window of the endoscope due to the transparent core material and efficient TIR. Specialty lenses or coatings can be used to increase the light transmission even further. The PLTR5-24MM-PR2 is capable of transmitting up to 24 mm of light, making it highly efficient for long distance transmission purposes.

Conclusion

Light pipes are essential components when it comes to the transmission of light, from laser diodes to medical endoscopes. The PLTR5-24MM-PR2 is one such light pipe, providing efficient transmission of the light due to its high-quality core material coupled with total internal reflection. This device is capable of transmitting light over long distances with very little energy loss, making it the ideal choice for many optical-based applications.
