JAI Apex Series – AP-5100T
The JAI Apex Series transforms colour imaging from interpolation-based estimation into deterministic, spectrally separated data acquisition. Built on a 3-CMOS prism architecture and powered by Sony’s latest Pregius S BSI sensors, Apex delivers true per-pixel RGB values with measurable spectral integrity.
In next-generation inspection systems, colour is no longer aesthetic information. It is a measurable parameter that directly impacts classification reliability, yield stability, and process control.
Stop estimating. Start measuring.
Bayer-based cameras reconstruct missing colour channels through de-mosaicking. That process introduces spectral overlap, interpolation artifacts, and uncertainty — particularly visible in saturated tones, fine structures, and high-dynamic scenes.
Apex captures colours directly.
The JAI Apex Series uses a precision-engineered dichroic RGB prism to separate incoming light across three dedicated CMOS sensors. Each sensor captures its channel without shared pixels or interpolation, delivering exceptional colour accuracy.
The result:
- Higher colour accuracy in CIE L*a*b* space
- Improved spatial fidelity at edges and microstructures
- Stable discrimination of subtle hue and intensity deviations
- Predictable behaviour under mixed illumination
Transforming colour from a visual attribute into a controlled inspection variable
Control the spectrum. Control the outcome.
Minimal colour crosstalk and superior light transmittance
Precision-engineered hard dichroic prism filters deliver steep spectral separation and superior light transmittance, producing truer, more saturated colours and revealing the finest visual differences, even in high-speed or low-light applications.
Independent channel exposure control
White balance is achieved by shutter timing per R/G/B channel, not by gain amplification. Noise remains at the sensor floor.
Lateral Chromatic Aberration Correction
In-camera compensation reduces lens-induced dispersion errors, improving edge alignment across channels and extending usable optics range.
Xscale sub-pixel scaling
Floating-point scaling enables fine adjustment of effective resolution and sensitivity without mechanical reconfiguration.
Multi-ROI and sequencer functionality
Multiple exposure strategies and inspection zones can be executed within a single acquisition cycle, ideal for high-contrast or multi-material scenes.
On-board colour space conversion
Direct output in HSI, CIE XYZ, sRGB, Adobe RGB, or custom matrices reduces host-side computation and simplifies calibrated workflows.
Engineer certainty into every pixel.
Specifications
Apex provides system-level advantages unavailable in single-sensor colour cameras. Backside illumination enhances quantum efficiency while maintaining compact optical format and high-speed readout performance. It advances the platform with Sony’s 4th-generation Pregius S IMX548 BSI sensors, delivering:
- 3 × 5.1 MP (2472 × 2064 per channel)
- 2.74 µm pixel pitch
- Up to 75 fps
- 5GigE Vision, CameraLink, and CoaXPress interfaces
- 24-bit and 30-bit RGB output
Engineered for integration into high-speed, automated production systems
- 3G vibration resistance
- 10G shock tolerance
- Wide operating temperature range
- Compact 54 × 54 × 74 mm housing
- Full GenICam compliance
When colour determines yield, precision becomes strategy.
Apex is deployed where classification tolerance is narrow and inspection reliability defines profitability. In each environment, precise spectral separation translates into consistent inspection decisions and reduced uncertainty in automated processes.
- Food grading and material differentiation
- Automotive surface and trim validation
- MLCC verification and micro-assembly control
- PCB and semiconductor inspection
- Print inspection and colour patch validation
- Pharmaceutical tablet coating analysis

FAQ
Dans quel cas une caméra à prisme est-elle préférable à une caméra Bayer ?
Lorsque la précision colorimétrique est une exigence fonctionnelle, et non une simple préférence. Si des données de couleur incorrectes entraînent des erreurs d'inspection ou des défauts non détectés — en tri pharmaceutique, en classification de composants électroniques ou en vérification d'impression, par exemple — une approche à prisme supprime l'incertitude introduite par l'interpolation.
Quel modèle choisir — AP-1600T, AP-3200T ou AP-5100T ?
Les exigences en matière de résolution et d'interface déterminent le point de départ approprié. L'AP-5100T intègre en outre la correction de l'aberration chromatique latérale et le redimensionnement Xscale, pertinents lorsque la précision optique ou la flexibilité du champ de vision sont des critères déterminants. Notre équipe technique peut vous accompagner dans le choix du modèle en fonction des paramètres spécifiques de votre application.
La Apex Series est-elle adaptée à l'imagerie NIR ou multispectrale ?
Oui, via le concept Flex-Eye de JAI. Des configurations de prisme personnalisées sont disponibles avec des options de bande spectrale étendue, notamment R-NIR, permettant une acquisition simultanée en lumière visible et en proche infrarouge. Les applications typiques incluent la différenciation de matières organiques dans l'industrie agroalimentaire et l'inspection pharmaceutique.
Quels logiciels sont compatibles avec la Apex Series ?
Tous les modèles Apex sont entièrement conformes GenICam et compatibles avec Common Vision Blox (CVB), Sapera LT et les principaux SDK de vision industrielle standard. Aucune pile de pilotes propriétaire n'est requise.
STEMMER IMAGING peut-elle accompagner une analyse de faisabilité applicative ?
Oui. Dans le cadre de nos Engineering Services, nous proposons des tests de faisabilité et des prestations de conseil technique pour évaluer si la Apex Series répond à vos exigences d'inspection. Contactez votre équipe STEMMER IMAGING locale pour discuter de votre application.
