Imperx T8820 Review: Specs & Applications
Updated: 7 days ago
Imperx T8820 is an interline CCD camera using the onsemi KAI-47051 sensor and Camera Link Full output. Its documented standard image grid is 8856 × 5280. Price: Request a quote.
The camera should be selected as part of an imaging system rather than evaluated from one headline specification. The useful result is an image that reveals the required feature at the right time, followed by a reliable inspection or measurement decision. This review considers the documented acquisition package, optical implications and practical purchasing scope for T8820.
Quick Verdict
T8820 supplies the same large image-grid class as T8810 with a faster Camera Link Full acquisition path. The increased rate comes with a different interface and output-bit-depth scope. It is a candidate when those specific changes improve an established or deliberately designed detailed inspection system.

Design and Optical Requirements
A 57 mm sensor diagonal is a substantial optical requirement. The manual lists M72 mounting for T8810 and T8820; an ordinary small-format machine-vision lens should not be assumed to cover it. Evaluate focus, distortion and illumination at the perimeter as well as the center, with the actual object height and fixture.
Acquisition Speed and Integration
The manual identifies T8810 as Camera Link Medium with 8/10/12-bit output at up to 3.3 fps. T8820 uses Camera Link Full with 8/10-bit output at up to 6.7 fps. Its interface limits delivered pixel depth even though the camera digitization can support a greater depth. Match receiving hardware and the image representation to the exact model.
Programming and Image Processing
The documented capabilities include programmable image region, trigger inputs, strobe outputs, temperature monitoring, gain and exposure configuration. Use those controls to establish a repeatable acquisition recipe for the station. Determine which adjustments are performed in the camera and which belong in the host software. Store the chosen settings with the inspection configuration so an operator or service technician can reproduce the image used during commissioning. A parameter change should be evaluated against both good and faulty samples before it becomes the production default.
Image Data and Host Capacity
As an engineering estimate, a 8856 × 5280 frame represented as one uncompressed 8-bit value per pixel contains about 46.76 MB of pixel data, using decimal megabytes. This excludes transport overhead and metadata. It is a sizing example, not a measured camera transfer rate; other output representations change the data volume. Multiply the selected frame size by the planned acquisition rate when budgeting host memory, processing and storage, then validate the complete pipeline under realistic load.
T8820 Applications and Use Cases
Large-field surface or component inspection and controlled measurement can merit a representative trial. The relatively low full-frame rate should fit the presentation and station cycle. A dense image of a reference chart does not establish performance on a real object with height variation, reflections and difficult defects.
Building a Useful Acceptance Trial
Prepare representative parts or scenes that include the smallest required feature, normal production variation and realistic faults. Confirm the field of view and exposure before tuning the inspection. Record wrong accepts, wrong rejects, missing frames and the complete trigger-to-decision timing. A trial should also show what happens when the expected image is absent or unusable. This connects camera selection to the station's actual acceptance requirement rather than relying on a sharp reference picture.
T8820 Price and Value
Price: Request a quote. Ask for the complete T8820 ordering code and an itemized scope covering the camera, suitable optics, receiving hardware, cables, power and commissioning. Compare quotations for the same image format, acquisition mode and integration scope. The cost of a camera component is different from the cost of a working inspection station. Evaluate any financial return with the plant's actual labor, defect, rework and maintenance data; no universal payback period follows from these specifications.
Comparison and Selection
T8810 and T8820 share the documented standard image dimensions and sensor family but differ in output taps, interface mode, supported delivered bit depth and rate. T8820 should not be specified as merely a faster Medium-mode unit. A modern replacement also needs the unusually large optical field and installed processing assumptions addressed.
Ordering, Environment and Lifecycle
The A3 directory describes T8820 with Medium output, while the manufacturer manual explicitly specifies Full output and 8/10-bit delivered formats. This review follows the manual for that distinction. Require the current datasheet and supported receiving configuration in the quotation, together with lifecycle, cooling and lens-mount scope.
Pros and Cons
Pros
Documented 8856 by 5280 standard image grid.
Defined interline CCD acquisition architecture.
Documented Camera Link Full receiving path.
Cons
Current lifecycle and ordering configuration require confirmation.
Optical performance must support the selected image field.
Capture rate and processing throughput are separate requirements.
Who Should Buy T8820?
Shortlist T8820 when its documented sensor, interface and acquisition mode match the imaging task and the team can demonstrate the complete host pipeline. Use the sample trial to establish whether the relevant features remain distinguishable under the expected lighting, presentation and motion. Before purchase, settle the optical configuration, ordering variants and support requirements. The best choice is the configuration that satisfies the acceptance criteria with a maintainable system architecture.
T8820 FAQ
What is the native resolution of T8820?
8856 × 5280 pixels is the documented native image format. Evaluate the optics and required feature scale alongside that pixel count.
Which shutter architecture does it use?
The model uses an interline CCD with programmable electronic exposure. Evaluate its documented acquisition timing rather than substituting a CMOS shutter description.
What interface is required?
Camera Link Full is the documented acquisition interface. Match the receiving hardware and software to the exact ordering configuration.
What is the maximum frame rate?
The documented rate is Up to 6.7 fps. Confirm the specified operating mode; maximum capture rate is not a guarantee of completed inspection throughput.
Which acquisition features are documented?
The product information includes programmable image region, trigger inputs, strobe outputs, temperature monitoring, gain and exposure configuration. Configure the selected functions around the actual trigger and image-processing requirement.
What should be included in a system comparison?
T8810 and T8820 share the documented standard image dimensions and sensor family but differ in output taps, interface mode, supported delivered bit depth and rate. T8820 should not be specified as merely a faster Medium-mode unit. A modern replacement also needs the unusually large optical field and installed processing assumptions addressed.
How much does the camera cost?
Price: Request a quote. Include the exact camera variant, optics, receiving hardware, power, cables and commissioning.
What should be tested before ordering?
Test representative good and faulty samples, the intended optical geometry, image timing, capture diagnostics and the complete result association with each inspected part.
Price: Request a quote. Final configuration, pricing, availability and support terms depend on the supplier's current quotation.
