Optics is the branch of science which deals with the properties of light and the behaviour of light when it interacts with matter. More specifically, lenses are the optical element which manipulate the propagation and direction of light. One such device is the CA11360_LAURA-D. The device is a wide angle objective lens used for medium voltage perimeter surveillance. This article will discuss the application field of the device and its working principle.

Application Field

The CA11360_LAURA-D lens is designed to be used in medium voltage perimeter surveillance applications, such as medium voltage electrical distribution grids, railway and road bridges, and long stretch power lines. All these applications share the commonality of large scale surveillance, as well as the need for a wide angle to capture the entire area. The device can be used both during the day and night without any light modification.

The CA11360_LAURA-D lens was specifically designed to cover an angle of view of 110 degrees, allowing for a wide field of view even when used in highly constrained locations. By covering such a wide angle field of view, the lens enables operators to be able to detect threats and take action before they reach the border. The lens also delivers high resolution images, even in low-light conditions.

Working Principle

The CA11360_LAURA-D lens relies on the principle of refraction. When light enters a medium with a different refractive index, the light is bent. This phenomenon can be observed when sunlight enters a swimming pool, when a glass prism breaks the light into its individual components, and when light passes through a lens. When a light ray enters the lens, it is bent towards the optical axis, and when it leaves the lens it is bent away from the optical axis. By manipulating the shape and size of the lens, and the refraction of the medium, the desired focal length, field of view, and other optical characteristics can be achieved.

The CA11360_LAURA-D lens consists of two individual lenses that are combined to form a single element. The front elements are designed to have a larger curvature than the rear elements, giving the lens a wide field of view and depth of field. This design also allows for a greater focusing range when objects are closer or farther away from the aperture.

In addition to refraction, the CA11360_LAURA-D lens also employs the principles of interference and diffraction. Interference involves the superposition of two optical waves, causing the light to be attenuated in certain areas and amplified in others. This allows for improved resolution of the target image. Diffraction involves the spreading out of a light wave as it passes through an aperture. This phenomenon allows for improved image quality and capture of wider angles.

Conclusion

In conclusion, the CA11360_LAURA-D lens is used in medium voltage perimeter surveillance applications due to its wide angle of view and ability to deliver high resolution images. It takes advantage of the principles of refraction, interference, and diffraction, allowing for improved resolution of the target image. The device is suitable for both day and night surveillance, and its size and shape make it suitable for use in highly constrained locations. The CA11360_LAURA-D lens is a valuable tool for medium voltage perimeter surveillance applications.
