Total Internal Reflection
An Overview of TIR and TIR in Diverse Fields
Total Internal Reflection (TIR)
Total Internal Reflection (TIR) is a phenomenon that occurs when light rays travel from a more optically dense medium to a less optically dense medium, such as from water to air. When a light ray strikes the boundary between the two media at a certain critical angle, it is completely reflected back into the denser medium rather than being transmitted through the boundary. This critical angle is determined by the refractive indices of the two media. TIR is an important principle used in a variety of optical applications, such as fiber optics and prisms.
Total Indicator Reading (TIR)
Total Indicator Reading (TIR) is a measurement used in manufacturing to assess the roundness of a cylindrical part relative to a center line. It is expressed as the total diametric deviation, which is the maximum difference between the measured diameter of the part at any point and the nominal diameter. TIR is an important parameter for ensuring the proper fit and function of cylindrical components in various applications, such as machinery, automotive parts, and medical devices.
Transports Internationaux Routiers (TIR)
Transports Internationaux Routiers (TIR) is an international agreement that establishes a system of customs clearance for the transport of goods across borders. It allows goods to be transported under a single customs seal, eliminating the need for multiple inspections at each border crossing. TIR is widely used by transport companies and logistics providers to facilitate cross-border trade and streamline customs procedures.
