Optics - Light Pipes

Light pipes are long optical fibers that transmit light from one end to another. The optical fibers are used to carry light over long distances with minimal loss of light. One example of a light pipe that is commonly used is the VLP2-D-3. This article will explore the application field and working principle of the VLP2-D-3.

The VLP2-D-3 is a light pipe that is designed for low-level light transmission. This light pipe is primarily used for medical, industrial, and aerospace applications. It can be used for applications ranging from medical imaging to lighting in aircraft to fiber optic cables for data transmission. Its lightweight and flexible structure makes it ideal for installations in hard-to-reach places.

The VLP2-D-3 has a core diamter of 2.7 mm and an optical power rating of 10 mW CW. It has an outer diameter of 5.3 mm and a numerical aperture of 0.50. It is designed to be used in transmission and reflection modes with its operating temperature ranging from -40° C to +85° C. It has an effective length of up to 6.7 meters and a working voltage of 2.5V.

The working principle of the VLP2-D-3 is based on the principle of Total Internal Reflection (TIR). This principle states that when light that is travelling from an optical fiber to a material with a lower index of refraction, such as a glass prism, it will be reflected back to the fiber instead of passing through the material. This is accomplished through the angles of the prism which help to control the angle in which the light is reflected. The total internal reflection helps to keep the light intact over long distances by preventing any losses due to transmission.

The VLP2-D-3 is also designed to be resistant to shock and vibration. This is accomplished by using silica-coated optical fibers. Silica-coated optical fibers are more resistant to shock and vibration than standard glass fibers because they are more flexible and less brittle. The coating also helps to reduce signal losses due to mechanical strain on the optical fibers.

The VLP2-D-3 is a versatile light pipe that is ideal for a wide range of applications. Its design enables it to be used in a variety of situations, including those with challenging installation requirements. Its ability to transmit light with minimal loss over long distances and its resistance to shock and vibration make it an ideal choice for a variety of applications.
