Adjustable Field Splitter eliminates need for dual cameras

If you need to:

  • inspect the same object from different angles
  • see the edges of a large object, or multiple widely spaced objects while still maintaining high resolution
  • quickly and easily change your camera's viewing area without significantly changing the optical path length
  • view an area where a camera won't fit

The Adjustable Field Splitter (AFS) delivers it all and more.

For the first time here's an out-of-the-box optical accessory that lets you solve the problem without expensive engineering and fabrication. If you can turn a screw and focus a lens, you can use the AFS to save time and money.

Don't add that second expensive line scan or high end area scan camera - add an Adjustable Field Splitter.


Light Works has basic AFS kits available along with application notes and suggestions.

We would be happy to confidentially discuss your specific needs in detail and provide the optical engineering for your particular AFS application.

Take a look a some of the examples and how it works, then call us to find out how we can make Light Work for you.

How the Adjustable Field Splitter Works

how the AFS works

  • The AFS threads onto lens
  • A metallized prism splits the view into 2 fields
  • The optical path of each field travels down the "articulated periscope" arms
  • Each rotary joint is adjustable and lockable
  • Each arm of AFS views a different object, or
  • Two arms can view same object from different angles
  • Regardless of adjustment position or arm angle, the optical path remains constant

Example Applications

Printed circuit board inspection
View widely spaced components at high resolution.


Inspect both ends of single object
Use a single camera to view two different planes of same object.


High resolution bottle gauging
Use the AFS to obtain high resolution diameter measurement by imaging opposite edges of a wide mouth bottle.


Web guidance and inspection Inspect the widely spaced edges of interest in a web guidance application.


Complementary diameter gauging Perform precision diameter checks from two angles using one camera.


360 degree object inspection A four-arm AFS can give your single camera an undistorted full view.
