Thanks to the appearance of many single board platforms dedicated to amateurs and hobbyists, minicomputers have become popular among enthusiasts of robotics and electronics. Check out other models available in Botland.
Lenses for cameras - Official special camera for the Raspberry Pi has a lens built depending on their own needs, we do not have the possibility of self-disassembly and installation of other lenses in their place. If you are doing macro photography and Your requirement is to obtain close-up details with high resolution and wider fields of view, for this purpose it is necessary to take lenses for cameras from Arducamthat greatly extend the range of standard web-cameras of this brand for Raspberry Pi. Because of this, you will get more control over the image when taking photos and recording videos.
To meet the market requirements and considering new possibilities in lens technology, designers with the ArduCam has developed a set of lenses for the Raspberry Pi which are mounted on the threads of the M12, which allow to record images with a long focal length, as well as in the “fish eye”. Each of the ten lenses included in the kit is labeled with diameter, which allows you to easily and quickly find and replace the lens depending on Your needs.
What are the main parameters that characterize lenses for cameras?
In order to choose the right lens for you, take a look at the theoretical side, which significantly affects its practical application. The main parameter of the lens, which determines its ability focused is its focal length, i.e. the distance from the geometric lens center to the geometric center of its matrix. A characteristic feature lenses with variable focal length, is the ability to adjust their sensitivity. The zoom lens is calculated as the ratio of the focal length to narrow the telephoto end, the focal length at the wide end. Then the lens can change the size of the visible image obtained on the screen, depending on zoom. An important parameter which is worth paying attention to is the field of view of the lens depends on the focal length and determines the maximum angle to have the image through the lens, depending on its diameter. The angle, usually measured with the assumption of infinite abilities, unifying the lens and can be easily calculated if you know the value of the focal length and image size.
