For OEMs building systems for series production—whether in machine vision equipment, medical devices, or global security products—camera repeatability and reproducibility are just as crucial as raw performance. Image uniformity affects system accuracy by ensuring measurements closely align with the true value.

However, a measurement system’s precision depends on both repeatability (consistency under unchanged conditions) and reproducibility (ability to replicate results). Below is a comparison of accuracy versus precision for clarity.

Repeatability: Consistency Under Unchanged Conditions

A general definition of repeatability refers to the variation in measurements taken by a single person or instrument on the same item under consistent conditions. In camera terms, this means maintaining consistency despite changing factors like temperature, vibration, and time.

To achieve this, camera design must incorporate specialized functionality to control overall performance, ensuring reliable results regardless of external variables.

Reproducibility: Camera-to-Camera Consistency

Reproducibility is the ability for an experiment or study to be accurately replicated by others independently. For cameras, it refers to consistency across multiple units.

This involves rigorous manufacturing procedures such as incoming inspection, alignment, and final testing to verify reproducibility.

Adimec’s Approach: Precision Through Process

At Adimec, we ensure camera reliability through a series of controlled processes:

  • Every image sensor undergoes an initial test to meet our specifications.
  • We employ highly precise image-sensor mounting and alignment in six degrees of freedom (3 translational + 3 rotational), guaranteeing pixel consistency within defined tolerances.

Additionally, each camera goes through individualized assembly and testing with mechanical and electrical adjustments. This ensures uniformity across all units.

Benefits for OEMs

Repeatability and reproducibility reduce system downtime by minimizing the need for software adjustments or customer support. They also enable more complex measurement algorithms (like 3D imaging) to be implemented efficiently.

Final Testing: Ensuring Uniformity in Series Production

Thorough final testing ensures every camera module is nearly identical, supporting simpler tool matching and automated setups rather than manual alignment each time.

For OEMs where cameras are critical system components, these properties support precision requirements while contributing to overall accuracy. Learn more about the differences between camera vs. sensor performance in our white paper.
