Lens calculator - Calculating the focal lengthThe 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....
HFOV & EFL Calculator The following calculators compute the Horizontal Field of View (HFOV) or Effective Focal Length (EFL) of a camera and lens system, for any sensor format. Using the EFL calculator, enables system engineers to find a lens according to pre-determined FOV, which will enable...
In case of a stereo camera, such as our Karmin3 3D stereo camera, the calculator also helps you selecting the baseline distance and it provides information on the expected depth error. You have several options for determining the focal length: you can enter the focal length manually, specify ...
Focal length calculator When an object is located outside the sphere center of a concave spherical mirror, it becomes an inverted and reduced real image, which is located between the focus and the sphere center; when the object is located between the focus and the sphere center, it becomes ...
Calculator for Focal Length of a Lens Refractive index: Radius 1: (0 = no curvature) Radius 2: (0 = no curvature) Thickness: Focal length: calc Enter input values with units, where appropriate. After you have modified some inputs, click the “calc” button to recalculate the output...
An online focal length calculator can help you make these calculations. You can also determine focal length by measuring the distance at which a lens focuses on a distant source (or by using a tool called an optical bench). But, in practice, an understanding of how focal length and ...
