The MV-CA003-50GC from Hikrobot represents a significant step up in light sensitivity for color imaging. Its 1/3″ color CCD sensor offers a larger surface area compared to 1/4″ models, capturing more light per pixel. This, combined with a global shutter and a VGA resolution streamed at up to 200 fps over GigE Vision, makes it ideal for applications demanding both color accuracy and performance under varying lighting conditions.
Beyond the core sensor, the MV-CA003-50GC boasts a robust feature set. It utilizes a global shutter for crisp imaging of moving objects, eliminating motion blur and spatial distortion. The Gigabit Ethernet interface provides reliable, long-distance data transfer up to 100 meters with standard cables, and supports Power over Ethernet (PoE) for single-cable simplicity. It adheres to the GigE Vision and GenICam standards, ensuring seamless integration.
Key parameters include the pixel clock, which influences the maximum achievable frame rate at full resolution. The device’s dynamic range and signal-to-noise ratio (SNR) are also critical, especially for color applications where subtle shade differences matter. The CCD sensor typically provides a high dynamic range, preserving detail in both bright and dark areas, which is vital for inspecting objects with high contrast.
The 1/3″ format is a sweet spot in machine vision, offering a great balance between size, sensitivity, and lens availability. A larger sensor also allows for a shallower depth of field, which can be used to isolate objects from a busy background. For color CCDs, the larger pixel area often translates to better color separation and lower crosstalk between R, G, and B channels, yielding more accurate color reproduction.
This makes the Hikrobot model particularly suitable for scientific imaging and high-precision quality control. While modern global shutter CMOS sensors are catching up, CCD sensors at this price point often deliver superior image quality for color-critical tasks, with less fixed-pattern noise and better linearity.
In pharmaceutical packaging, the MV-CA003-50GC can verify the correct color printing on boxes, ensuring patient safety. The food industry uses it for advanced sorting — not just by ripeness, but also by detecting bruises or foreign material that have a distinct color signature. Its 200 fps speed is ample for high-speed sorting lines of nuts or small fruits.
The MV-CA003-50GC positions itself as a high-performance alternative that delivers 80-90% of the core imaging performance at a fraction of the cost. For OEMs and system integrators building cost-sensitive yet performance-oriented systems, this value proposition is extremely attractive. It performs reliably in typical factory environments.
Lighting remains the most critical component. For color imaging, bright, uniform white light is mandatory. High-CRI LED lights are preferred. The choice of lighting angle depends on the surface texture of the object. It’s often necessary to experiment to find the setup that best highlights the color features of interest while suppressing glare.
