7 hours ago In this case, the focal point is to the right and so the lens is converging light. Next, measure the radius of curvature of the lens. In this example, the radius is measured to be 5mm. Finally, calculate the focal width using the formula above: f = – R / 2. f = – 5mm / 2. f = – 2.5mm.

9 hours ago The focal length f´ virtually serves to calculate the required lens and is thus the most important specification to characterise an (entocentric) normal lens. The theoretic value of the focal length calculation serves to find the best suitable optics. Typical increments of focal lengths for C-mount lenses are e.g. (1.8, 2.8, 4, 6,) 8, 12, 16 ...

1 hours ago Sep 16, 2015 . Field of View (FOV) = 90mm Working Distance (WD) = 400mm Sensor Size = 10.67mm – We will calculate for a 90mm horizonal FOV, in turn use the horizontal sensor dimension The basic formula to calculate the lens focal length is as follows: FL = (Sensor size * WD) / FOV Using the values from our application, FL = ( 10.67mm * 400mm ) / 90mm FL = 47.4mm

How is the camera focal length calculated? The focal length of a camera is the distance from the center of the lens to the focal points. If the focal points are closer to the lens center, it means the lens has more optical power to converge the light.
Effective Focal Length (EFL) is the focal length affected by the camera’s crop factor. The numbers in the lens’ manual show some focal length values that this particular lens can use. For instance, 15-30mm means that the lens can be anywhere from 15 mm 30 mm.
