Which version is right for you?
| Imatest 5.0: All functions of Imatest Image Sensor have been incorporated into Imatest Master. |
Imatest is available in several GUI (Graphic User Interface)-based versions.
- Studio, with everything individual photographers need to test their cameras and lenses.
Studio is only available to individual photographers. - Master, the full-featured industrial-strength version for engineers and scientists who develop and evaluate imaging systems. Acquire images directly from several manufacturer’s development systems. Images can be updated and analyzed in real time with the Rescharts, Multicharts, and Uniformity-Interactive modules.
- As of Imatest 5.0, Image Sensor (IS) has been discontinued. All functionality can now be found in Imatest Master.
Imatest is also available in non-GUI Industrial Testing (IT) versions (both EXE and DLL) that are suitable for automated testing in production lines.
