Lenses & Mounts

The required focal length (zoom value) of a lens is critical to obtaining great photo-finish images. If the focal length is too high, then it will not be possible to zoom out enough to see the entire finish line. If the focal length is too small, then there will be a lot of dead space at the top and bottom of the image, causing a poor resolution for the objects of interest.

The best way to calculate the required focal length is to use the Lens Focal Length & Frame Rate Calculator (LensCalc.xls) spreadsheet available online.

Instructions

• To find the recommended lens:

1. Download the Lens Focal Length & Frame Rate Calculator (LensCalc.xls).
2. Enter the required parameters in the Lens and Scar Rate Calculator (left).
   1. Camera Height
   2. Distance from the camera to the finish line
   3. Width of the finish line
   4. Max height objects of interest
3. Look at row 9 to find the Recommended Lens for each camera model.

User that have upgraded to the latest generation of EtherLynx Vision-Series cameras may already know what lens is required on an older camera. To quickly find the equivalent lens use the Lens Focal Length & Frame Rate Calculator (LensCalc.xls) spreadsheet available online.

Instructions

• To find the equivalent lens:

1. Download the Lens Focal Length & Frame Rate Calculator (LensCalc.xls).
2. Select the current camera model (AK2) in the Lens Equivalency Calculation (right).
3. Enter the focal length range of the current lens (AK3, AM3).
4. Find the new camera below to see the equivalent range.

The table below describes the mounts compatible with each EtherLynx camera model:

Not all lens mount types offer lenses that are fully remote controlled. See the table below to know available options:

There is a long list of various lens formats available on the market. In many cases, it is preferred to use a lens that will allow using the cameras full resolution. Below is a table with common lens formats and whether they offer full resolution for EtherLynx cameras.
