Paraxial raysin physics

Paraxial rays are a type of light ray that are close to the optical axis of a lens or mirror. They are used in geometric optics to simplify calculations and describe the behavior of light in simple optical systems.

No, paraxial rays are only accurate for describing light propagation in simple optical systems. In more complex systems, such as those with curved surfaces or varying refractive indices, paraxial ray approximation may not be accurate and more advanced techniques must be used.

FLIR Systems designs, develops, manufactures, markets, and distributes technologies that enhance perception and awareness. We bring innovative sensing solutions into daily life through our thermal imaging systems, visible-light imaging systems, locator systems, measurement and diagnostic systems, and advanced threat detection systems. Our products improve the way people interact with the world around them, enhance public safety and well-being, increase energy efficiency, and enable healthy and entertained communities.

In diagrams, paraxial rays are typically represented as straight lines that are close to the optical axis. They may also be represented as dotted lines to show that they are not the actual path of light, but rather an approximation for calculation purposes.

Paraxial rays are significant in optics because they allow for simplification of calculations and the description of light in simple optical systems. They are also important in the design of lenses and mirrors for use in various optical devices.

Pioneers in thermal imaging, we were founded in 1978, originally providing infrared imaging systems that were installed on vehicles for use in conducting energy audits. Today our advanced systems and components are used for a wide variety of thermal imaging, situational awareness, and security applications, including airborne and ground-based surveillance, condition monitoring, navigation, recreation, research and development, manufacturing process control, search and rescue, drug interdiction, transportation safety and efficiency, border and maritime patrol, environmental monitoring, and chemical, biological, radiological, nuclear, and explosives threat detection.

Paraxial rays are different from other light rays in that they are close to the optical axis and make small angles with the axis. This allows for easier calculations and simplifies the description of light in simple optical systems.
