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....
Lens Focal Length and Stereo Baseline Calculator This calculator helps you selecting the right lenses for your cameras. It does so by computing the desired focal length, the corresponding field of view and the expected depth of field. In case of a stereo camera, such as our Karmin3 3D ...
This calculator determines the focal length required to image a target at a specified field of view and working distance. To run, select the size of
Thanks to the angle of view option, we don't really need an additional field of view calculator — we have everything ready! 🔍 Thanks to our lens focal length calculator, you may also find the magnification— it allows us to measure how the size of an object changes when transferred ...
35mm equivalent Focal Length Multiplier Calculator This calculator allows you to calculate the 35mm equivalent Focal Length for digital camera at specific sensor size. Focal Length and Angle of view. The focal length of the lens is the distance between the lens and the image sensor when the sub...
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 easy search of the ...
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 ...
And since crop factor describes sensor size, we can compute sensor dimensions from it, using the 4th calculator below about using Equivalent Focal Length. Calculate Equivalent Focal LengthEquivalent Focal Length for 35 mm film (1x) = Crop Factor × Focal Length of lens on THIS camera ...
The focal length is, by definition, the distance from the lens (considering a thin lens) at wich the image of an object placed at the infinity will be sharp. The focal length is then only depending on the lens carachteristics. According to the size of th
