INFO LENS CALCULATOR

FIELD OF VIEW (FOV) CALCULATOR

Select Sensor size:
Select Units of measure:
Distance to object:
Object (or FOV) width:
Object (or FOV) height:
Lens focal length: (mm)


HOW TO CALCULATE:

Distance to object:
  1. select camera sensor size
  2. enter object width or height
  3. enter lens focal length
  4. click “Calculate Obj Dist” button
Object size (FOV):
  1. select camera sensor size
  2. enter object distance
  3. enter lens focal length
  4. click “Calculate Obj Size” button
Lens focal length:
  1. select camera sensor size
  2. enter object distance
  3. enter object width or height
  4. click “Calculate focal length” button

Having established the focal length it is then important to consider other aspects of the lens ‘specification’ such as minimum working distance, resolution and resolving power. There are hundreds of lenses to choose from so please give SDVision a call to discuss your application so we can offer further advice.


FOV RESOLUTION (PIXEL SIZE) CALCULATOR



HOW TO CALCULATE:

Pixel Size:
  1. enter CCD width and height in pixels (ex: 640 x 480)
  2. enter object or FOV width and height (ex: 4 x 3.75)
    Note: width and height will be adjusted to the maintain the correct FOV proportions.
  3. click “Calculate” button
