Focal Length Of Lens Calculator

Focal Length Of Lens Calculator. This calculator computes the 1/e^2 1/e2 spot diameter of a collimated gaussian beam whose wavelength is \lambda λ and diameter at lens d d when it is focused with a lens having a focal length f f. The formula of focal length for the measurement described above is:

It does so by computing the desired focal length, the corresponding field of view and the expected depth of field. The stronger the power, the wider field, and there is a mapping relationship between the field of view and the focal length. The sign convention used is as follows:

Using A Common Lens Focal Length, Use Calculator #2 To Determine The Working Distance Necessary To Get Your Desired Field Of View.


If the focal points are closer to the lens center, it means the lens has more optical power to converge the light. Focal length enter pixel, resolution, working distance and fov sensor pixel size (u) enter the sensor pixel size resolution horizontal. Image formation in a lens takes place by the refraction of light at its two bounding surfaces.

This Calculator Uses The Actual Focal Length Of The Lens, Not The “Equivalent Angle Of View Focal Length” That Photographers Talk About When Comparing Things.


The efl determines the field of view of the camera while the bfl. It enables easy calculation of an appropriate lens focal length, camera viewing angle, ip camera bandwith, storage capacity for records archiving and of other camera system parameters. Focal length of a thin lens is the distance from the center of the lens to the principal focus of the lens.

Or, Use Calculator #3 To Determine The Field Of View Resulting From A Fixed Working Distance.


The angle of view does, but not the focal length. Ultra high speed machine vision cameras; A field of view / fov lens calculator to help you determine the focal length of the lens you need.

Lens Calculation Tool For Determining Target Distance Of An Object And Focal Length Of A Lens.


Lenses having focal lengths of 6, 8, 12, 16, 25, 35 and 50 mm are commonly available. The following table can be used as an indication for the opening angle at specific focal lengths and sensor size. In many cases these aberrations can be compensated for to a great extent by using a combination of simple lenses with complementary aberrations.

This Calculator Determines The Focal Length Required To Image A Target At A Specified Field Of View And Working Distance.


The calculator uses the camera lens focal length equation. Additionally, the beam quality parameter m^2 m 2 can be specified if the beam deviates from an ideal gaussian. It does so by computing the desired focal length, the corresponding field of view and the expected depth of field.
