CFT - Compact Field Tester

The CFT (Compact Field Tester) is a compact, lightweight, self-contained camera test system supporting the IR or Visible spectral ranges. The CFT units are designed for use in a laboratory environment and outdoors in a field environment.

The CFT is available is three configurations:

  • The CFT-IR for testing infrared systems.
  • The CFT-VIS for testing visible camera systems. 
  • The CFT-IR/VIS-7 Tester for multi-band systems.

They house a lens-based (refractive) collimator, energy source (blackbody or visible light), and one or more targets, all in single compact, man-portable unit.

General Notes:

1. For additional configurations, please contact CI Systems.

2. General tolerances for mechanical dimensions and weights are ±10%.  For an ICD please contact CI Systems.

3. Mechanical interface between the CFT and the UUT is available upon request.

Notes for CFT-IR models:

4. Offered with four user-settable differential temperatures, set through a user-friendly PC interface

5. Includes five user-specified targets

6. Includes a manual target wheel (motorized wheel available upon request)

7. For accurate MRTD testing, the CFT-IR units should be used in the lab. A built-in s/w uses an algorithm to ensure that it emits the same radiance regardless of ambient temp.

Notes for CFT-VIS models:

8. Offered with a single user-defined target

9. Higher resolution is available upon request

10. Battery operation is limited to LED sources only

11. Optional for the CFT-VIS-3:

•       The CFT-VIS-3 can be configured with the SR-300N Integrating Sphere highly-uniform source or with a visible LED-based Backlight

•       RS232 communication for controlling the luminance of the SR-300N Integrating Sphere.

•       Tripod interface included

Notes for

CFT-IR/VIS-7 :

12. Cassegrain 1.5” central obscuration

13. For additional configurations, please contact CI Systems.
