lens calculator
Our Lens Calculator allows you to calculate different parameters of machine-vision lenses (including focal length, field-of-view, working distance, etc.) according to different parameters of the camera sensor.
Based on this, the calculator works in different calculation modes, which you can activate via the icons below or directly using the bottom dropdown:
focal length
field-of-view
working distance
depth of field
effective f-number

focal length calculation - classic method
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, 25, 35, 50 and 75 mm.

working distance calculation - classic method
The object distance refers to the distance between the object ("test object", "scene", also "field of view")
and the first principal plane of the lens groups somewhere in the optical system.
The often wanted, so-called "free working distance", from the test object to the front surface of the lens
can only be calculated by specifying the position and distance of the two principal planes and the real lens
length.
This means that the "working distances" calculated here are only approximate values.

aperture angle calculation - using Sensor/focal length
Entocentric lenses have a fixed aperture (opening) angle. Therefore the object field to be viewed can be increased or reduced by increasing or reducing the working distance. If the aperture angle is very large, a strong distortion of the optics must usually be expected.
Attention: The calculated aperture angles are based on simple geometric formulas. The calculated values differ widely from reality for extreme wide angle and fisheye lenses. Please consult the manufacturer's data sheets. Calculated aperture angles below 0.1 as well as beyond 178 degrees are declared invalid.

Depth of field calculation
The depth of field (DOF) is the range within which the object can move away from or towards the camera without resulting in a blurred image.
The depth of field depends on the adjusted lens aperture, the distance to the test object, the focal length and the pixel size of the camera. the double pixel size is often set taken permissible unsharpness, i.e. one pixel image unsharpness is accepted.
In an existing system, the field of depth can only be varied by means of the aperture of the lens.

imaging scale calculation - using Sensor/object size
Usually no focal length is indicated for telecentric measuring lenses or macro-lenses, which would serve to calculate and select the optics. These lens types are characterised by the imaging scale β (beta). It can easily be calculated.

effective f-number calculation
The values of the focal ratio indicated on the lens are normally calculated for an image from the infinite. In case of images from a short distance, particularly macro-images, the effective focal ratio can be calculated which results in the actual image brightness:
