Choosing a machine vision camera for identification tasks often comes down to resolution, speed, interface, and total setup cost. The Point Grey/FLIR Flea3 FL3-U3-88S2C-C, listed at USD 225.00, is a used camera body that offers high-resolution color capture, but you'll need to factor in additional components.
Quick verdict
For machine vision identification tasks that need an 8.8 MP color sensor in a compact USB 3.0 camera, the Point Grey/FLIR Flea3 FL3-U3-88S2C-C at USD 225.00 is a capable used option. The Sony IMX121 CMOS sensor and 21 fps frame rate suit stationary inspection and robotics setups where you can supply your own C-mount lens and locking USB 3.0 cable.
Who it suits
This camera fits buyers already comfortable with machine vision components. If you have a C-mount lens and a locking USB 3.0 cable, the Flea3 body alone gives you high-resolution capture without the added cost of a bundled kit. The 4096 x 2160 resolution is practical for identifying small part features, barcode reading, or quality checks in a controlled mount.
What stands out from the listed details
The 8.8 MP Sony IMX121 sensor captures color images at 21 frames per second, a useful balance for many real-time inspection stations. The USB 3.0 Micro-B interface supports data transfer with a 32-megabyte frame buffer, which helps smooth bursts when the host computer is busy. On-camera power, temperature, and status monitoring plus in-field updatable firmware are listed as design features for reliable integration. The 12-bit ADC and 1.55 µm pixel size are also included in the specification, giving you a sense of its imaging detail. The listed price of USD 225.00 is the amount you'll pay for the body alone.
Meaningful trade-offs
The biggest trade-off is that this listing is for the camera body only. You will need a C-mount lens and a locking USB 3.0 cable for operation, and those are not included. If you are starting from scratch, those additional purchases can add to the total cost. Also, the camera is described as lightly used, so consider how that fits your tolerance for pre-owned equipment in a production environment. For identification tasks, the 21 fps frame rate is adequate for many stationary or slow-moving inspections, but it may not suit high-speed sorting or conveyor lines. Within the listed specifications, the Flea3 offers solid resolution and a dependable interface for moderate-speed applications.
Product note: Point Grey/FLIR Flea3 FL3-U3-88S2C-C
This USB 3.0 machine vision camera uses the Sony IMX121 sensor to deliver 8.8 MP resolution at 21 fps. The used condition and C-mount lens mount make it best for someone who already has compatible optics. The listed brand is Point Grey and the condition is used, matching the description of a lightly used unit. If you need a camera for identification tasks and can supply the lens and cable, this is a practical choice at USD 225.00.
Bottom line
If you already have C-mount lenses and USB 3.0 cabling, the Point Grey/FLIR Flea3 FL3-U3-88S2C-C is a practical used camera for machine vision identification. Its 8.8 MP color sensor and 21 fps performance cover many inspection and robotics scenarios. Just make sure to account for the missing accessories in your total budget.
