What is a multi-sensor, prism area scan camera?

In a multi-sensor, prism-based area scan camera, incoming light is split into separate color channels using a dichroic prism and directed onto individual monochrome sensors. All sensors share a common optical path, ensuring that each pixel in every color channel corresponds to the exact same point in the scene at the same time.
Unlike Bayer-based area scan cameras, which reconstruct color from a single sensor using interpolation, prism-based area scan cameras capture full-resolution color information simultaneously. This results in highly accurate color reproduction, improved image quality, and consistent performance, even in applications requiring precise detail and stable imaging conditions.

While Bayer technology uses interpolation to estimate RGB values, prism technology separates incoming light to three precisely aligned sensors so that true RGB values can be captured for each pixel.

When to choose a multi-sensor, prism area scan color camera?

Multi-sensor, prism-based area scan cameras are the right choice when your application requires highly accurate and consistent color imaging. By capturing full RGB information for every pixel without interpolation, they deliver precise color data, ideal for inspection tasks such as color matching or detecting subtle color variations.

They are particularly beneficial in low-light or high-contrast conditions, as prism optics enable more efficient use of incoming light compared to Bayer-based cameras. This results in improved sensitivity, better contrast, and clearer detail across the entire image.

Prism-based area scan cameras also provide superior spatial accuracy, making them well suited for applications that require precise measurement or detection of fine features. In addition, independent control of each sensor allows for optimized white balancing and consistent image quality.

What are the advantages of prism cameras for color area scan applications?

True full-resolution color capture: Each pixel contains exact RGB information without interpolation, delivering highly accurate and reliable color data compared to Bayer-based cameras
No demosaicing artifacts: Eliminates interpolation-related issues such as color artifacts, false detail, or edge blurring, resulting in sharper and more precise images
Superior color accuracy and consistency: Minimal spectral overlap ensures clean channel separation, enabling vivid and stable color reproduction across the full image
Higher light efficiency: Dichroic prism optics allow more light to reach the sensors, improving sensitivity, contrast, and performance in low-light conditions
Enhanced spatial precision: Full-resolution color information preserves fine details, making prism cameras ideal for measurement, inspection, and detection of small features
Independent control per channel: Separate sensors enable optimized exposure and white balancing for each color channel, improving overall image quality
Stable long-term performance: Prism-based optical systems provide consistent imaging results over time, supporting reliable operation in industrial environments
Simplified system integration: Built-in color processing enables direct output in application-ready formats, reducing the need for additional image processing

For which applications are multi sensor prism area scan cameras most suitable?

Multi-sensor, prism-based area scan cameras are the right choice when your application requires highly accurate and consistent color imaging.

Food inspection

Prism-based separation eliminates color crosstalk, allowing precise grading of subtle ripeness and defect colors in fruits, vegetables, eggs, and meat, even under mixed illumination.

Food and Beverage

Display inspection

The RGB channel separation enables simultaneous inspection of red, green, and blue subpixels for brightness, uniformity, and dead pixel detection, with no leakage between channels.

Electronics (PCB, LCD, Wafer etc)

Electronic component and PCB inspection

Capture multiple inspection images, such as solder joint integrity, silkscreen alignment, and component presence, in a single pass using different lighting per channel.

Electronics (PCB, LCD, Wafer etc)

Pharmaceutical quality control

Low crosstalk imaging isolates true color differences in ampoules, capsules, and multi-layer tablets, improving detection of coating variations or contamination where Bayer sensors can be misled by color bleed.

Pharmaceutical and Cosmetics

Semiconductor and wafer inspection

Minimal spectral overlap allows the use of multiple illumination types (such as dark field, bright field, and backlight) or different wavelengths at the same time without channel contamination.

Electronics (PCB, LCD, Wafer etc)

Farming

Precision agriculture or intelligent farming has seen an exponential growth in the recent years. Removal of weeds or wild plants is of growing importance in intelligent farming.
