4.8 Lens Modeling

Several camera companies have included this and like information in their manuals. For reference material it is very useful.

The focal point is the point at which the image of an infinitely distant object is brought to focus. The effective focal length (f’) is the distance from the second principal point to the second focal point. The back focal length (BFL) is the distance from the image side of the lens surface to the second focal point. The object distance (OD) is the distance from the first principal point to the object.

4.9 2K and 4K LVDS Cable Harness

Our family of TDI cameras can be mated with the following framegrabbers:

National Instruments

Coreco

Metrox Meteor

Drawings that annotate the Bills of Materials, Assembly Instructions, and Wiring Diagram for each cable harness can be downloaded from our website www.fairchildimaging.com.

When using one of the following framegrabbers in your system, you can select and download the appropriate cable harness drawing that will provide you information to build your cable harness.
