This yields a value of 0.589+ for your camera, scope and focal reducer. This calculator computes the field of view seen by your camera and lens. Fov = (c x d)/f.
How to Choose CCTV Cameras
Take your device, do the math (or take the results from anywhere else) and decide yourself to choose a reasonable fov angle. The usual techniques involve measuring an object of known width. The only way to calculate the horizontal angle or field of view is to use manufacturer’s data and therefore tools with database of camera models, like ip video system design tool show the correct result: It depends on the build of the eyepiece, thickness of the lenses and it is also affected by magnification.

• f is the required lens size. So, if you have a 10cm object at 10m from the camera, and you want that to be 0.5mm (50px width), you need to place the sensor 0.5mm*10m/10cm=5cm behind the pinhole. Despair no longer, as our intuitive cctv lens calculator will help you bring everything you need into perspective. The field of view.

In many scenarios it is interesting to estimate the field of view that is covered by images produced by a given camera. The field of view depends on several factors such as the lens, the physical size of the sensor or the selected image format. The afov is the angle between any light captured at the horizonal, and any light.
