When you're outfitting a machine vision identification setup, the first big fork in the road is whether to invest in a capture device or in the tools that keep it accurate. The two products here sit on opposite sides of that decision: a used Cognex color camera with a matching lens, and a pair of calibration target boards. The right choice depends on which part of your imaging chain is missing.
Quick Verdict
If your line needs a working color camera right now, the Cognex IS7802C is the buy. It's a used unit in excellent cosmetic condition, pulled from a working environment, and it arrives with a lens. If your camera is already producing images but distortion or color accuracy is throwing off your identification results, the calibration target boards are the focused fix-they won't capture anything, but they give you the reference targets to check what your camera sees.

| Product | Listed Price | Price Bar | Condition | Best Use |
|---|---|---|---|---|
| Cognex IS7802C-363-50 Color Machine Vision Camera with Opto TC23016 Lens | USD 699.00 | Used | Capture color images with an integrated lens | |
| Pair of Machine Vision Lens Distortion Calibration Target Boards w/ ColorChecker | USD 180.00 | Used | Check lens distortion and color accuracy |
Where Each Product Wins
Cognex IS7802C: It wins when you need the actual camera. The package includes the camera body and the Opto TC23016 lens, and the used unit was verified in a working environment. You get a complete imaging front end for a single purchase.
Calibration Target Boards: They win when your camera is already installed and you need to validate its output. The pair combines distortion grids with color targets, and LED grid illumination means you can use them without relying on overhead lighting.
Product Notes
Cognex IS7802C-363-50 Camera with Opto TC23016 Lens
This is the complete capture solution in this comparison. The Cognex IS7802C-363-50 is a color machine vision camera, and it ships with the Opto TC23016 lens already attached. It's a used unit in excellent cosmetic condition, removed from a working environment. The MPN 821-10105-1R and country of origin Ireland give you concrete identifiers for tracking. Choose this if your machine vision identification rig needs a camera that can produce color images today, without waiting to source a lens. The limitation is the used status: even with an excellent cosmetic look, it has an unknown service history, and in a production line you'll want to run your own image checks before committing to it.
Pair of Distortion Calibration Target Boards with ColorChecker
The pair of calibration target boards is the accessory-angle solution. Each board combines distortion-calibration targets with ColorChecker color patches, and the set is battery powered with LED grid illumination, so you can use it on a bench or in the field without additional lighting. The two boards are labeled model/serial numbers 1-001-00 and 1-009-04, and the condition is used and fully operational. If your camera is already working but lens geometry or color response is drifting, these boards give you a repeatable reference to diagnose the problem. They won't capture images on their own, so if your project still needs a camera, these should be a companion purchase, not the main investment.
Final Choice by Use Case
For a new machine vision identification build where no camera exists, go with the Cognex IS7802C-363-50. For an existing system with image quality issues, the pair of calibration target boards is the practical next step. If you're equipping a bench from scratch, consider the camera first, then add the boards to build a calibration routine.
