You can define horizontal and vertical angle of lens what You selected for camera in first calculator. Have to use this calculator if You need angle of lens and You know focus distance of lens. Need CCD size of camera and focus distance only for angle define.

CCD size (diagonal)

Focus distance of lens:

mm

Horizontal angle (result): -

Vertical angle (result): -

Results are approximate!

You can define focus distance of lens if You can get width and height picture what do You want, if You know distance between camera and target in second calculator. You need size of tagret place and distance between camera and target and You are looking for optimal lens (angle). Fill CCD size and data about target place (width and height) in meters and distance of target in meter. If You fill width data first then calculator will fill data of height automatically.

CCD size (diagonal)

Width of picture:

m

Height of picture:

m

Distance of camera from target:

m

Focus distance of lens (result): -

You can define widht and height of created picture if You know focus distance of lens and distance between camera and target in third calculator. This caculator very useful if You know data of lens and distance between camera and target and You want to know how much space can see on screen. You can check haw many picture will be about target with current lens from current distance. Fill size of CCD and focus distance of lens (in millimeter) and distance between camera and target in meters.

You can define how many meters have to be if You know focus distance of lens and widht or height of monitored area in fourth calculator. This calculator very useful if You know data of lens and how much space You want see on screen and You are looking for distance between camera and target. Ex. You know focus distance of lens and You want to see defined size area on screen and don't know how many maters have to be between camera and target. Fill size of CCD and width or height of monitored area and focus distance of lens. If You fill width data first then calculator will fill data of height automatically.
