CamTest Smart – a Very Compact Testing System
TRIOPTICS offers a 100% testing technology for all essential image quality characteristics of camera modules in just one compact system. It integrates all test parameters in one device. Therefore, along with common optical and opto-mechanical parameters such as MTF, SFR, defocus, image plane tilt and rotation, and distortion, the system also covers additional sensor testing parameters, including OECF, dynamic range, white balance, relative illumination, spectral response and more.
Key Features:
- Optimized End-of-Line tester
- Testing of all essential image quality characteristics of camera modules in just one system
- Target projection: focusing or fixed collimators, test chart, integrating sphere
- Flexibility with regard to different camera types
- Flexible low to mid volume production and R&D
- Fully automated process

CamTest Software
The CamTest software supports the measurement parameters and their analysis:
- mage quality features: MTF
- Optomechanical properties: sensor position (tilt, rotation, defocusing)
- Other optical parameters: distortion, relative illumination, focal length
- Color characteristics: chromatic aberrations
- Lens light reflection
The software is especially user-friendly. The user is automatically guided through the measurement process. The values can be output as pass/fail output. Measurement certificates are generated directly from the software in order to ensure complete traceability.
