Optical lens

Optical physics is a discipline of physics which focuses on the fundamental study of light, specifically on its propagation in media and on its interactions with matter. It deals not only with visible light, but also with electromagnetic radiation in a wider range of optical frequencies – in particular, also with infrared light and ultraviolet light. Some aspects apply even in extreme frequency regions, such as the X-ray region.

We also offer much more sophisticated CAD software for CCTV design, like our IP Video System Design Tool, that has a built-in database of more than 9000 camera models.

Lens Focal Length = (Distance) * 3.2 mm / HorizontalWidth where 3.2 mm is the horizontal size of 1/4″ CCTV sensor (4.8 mm for 1/3″ sensor).

Optical physics plays a crucial role in many areas of science and technology, including imaging, spectroscopy, information processing, and telecommunications. For instance, it is the fundamental science behind everyday technologies like illumination, lenses and microscopes, as well as more advanced technologies like lasers, optical fiber communications, quantum cryptography and quantum computing.

History ofoptics

Traditional calculators cannot calculate focal length for modern wide video surveillance cameras. Modern security cameras with short lenses (2.1 – 2.8mm) have non-standard wide angles. For example 115 degrees.

Baroptics

When rays of light pass through a convex lens (the shape of lens shown in figure above) they tend to converge at a single point at some distance ahead of the lens. This distance between the lens and the point where they focus is known as the focal length as specified by the symbol f in the figure. In case of a CCTV camera, the lens focuses the rays at a point where the sensor is placed. The combination of the focal length of the lens and the size of the sensor determine the field of view of the CCTV camera. The shorter the focal length, the wider the field of view, and vice versa.

The standard formula above doesn’t work for such lenses. You need to have a database of camera models with horizontal and vertical angles provided by camera manufacturers.

In the earlier days,  rotating lens focal length calculators made out of paper were good and simple tools for quick calculation of the field of view. As well as the formula above. But you should not use this formula for modern wide angle cameras!

Laser physics can be considered a special field of optical physics, focusing on aspects which are relevant for the operation of lasers and laser amplifiers.

There is a substantial overlap with optics; however, the latter is an engineering discipline with substantial parts outside fundamental physics, e.g. dealing with the optimization of optical systems. Similarly, photonics involves a lot of optical physics, but also many other aspects of technology and applications. Optical physics can be considered as a fundamental scientific foundation for disciplines like optics and photonics.

Typical kinds of light interaction with matter are absorption and emission processes in various kinds of optical materials including not only largely transparent media such as optical glasses, but also doped insulators and semiconductors (both often used as laser gain media).
