DescriptionThe REDEYE-6A is a low cost thermal imaging IR sensor Using a ceramic pyroelectric arrayExtracted from the Dewalt DCT416 imaging thermometer
IRISYS (Infrared Integrated Systems Ltd), Northampton, UK, is promoting thermal technology for intelligent building. Using its own thermal imaging cameras, the company has developed a range of innovative solutions from people counting to security.
The REDEYE-6A is an array sensor using pyroelectric ceramic. The manufacturing process is simpler than it is for a micro-bolometer. The ceramic plate is attached on top of the readout integrated circuit and sealed with the IR window.
The definition of the REDEYE-6A is rather low: 31x31 pixels. It is optimized for low-cost application which do not need a great definition and high refresh rate. The same pyroelectric ceramic technology is used for higher definition array sensor, up to 47x47 pixels.
IRISYS has developed a system to compensate the low definition by adding a standard optical sensor and blending the visual and thermal pictures.
The Reverse Costing of the Dewalt DCT416 imaging thermometer is available in a separate report.

SYSTEM PLUS CONSULTING
Across the Enterprise, from marketing to purchasing and R&D, product manufacturing cost is a major factor which has to be measured and then optimized. Since 1993, System Plus Consulting’s mission has been to develop and sell the right tools and services to meet these costing requirements.
System Plus Consulting utilizes an engineering approach to cost. Cost models and technology expertise are combined to provide customers with an accurate and objective estimation of manufacturing costs and selling prices.
Headquartered in Nantes, France, System Plus Consulting is specialized in technology and cost analysis of electronic components and systems. During our 20 years in business, we have built and refined detailed cost models as the primary tools for hundreds of analyses. The highly qualified System Plus cost engineers combine broad and deep skills in semiconductor and electronics technologies with years of experience in cost modeling.
− Custom reverse costing analyses: technology analysis followed by cost evaluation
− Standard reverse costing reports: regular publications on innovative products (available from our catalogue)
− Costing tools: software tools combining models and data to perform cost analysis
System Plus Consulting analyzes any type of electronic devices and systems, with a special focus on semiconductor technologies. Major fields of technology and cost expertise are:
− Integrated Circuits
− Power Devices and Modules
− MEMS & Sensors
− Photonics: LED, Image Sensors
− Packaging including wafer level
− Electronic Boards and Systems
Our analyses are used by Purchasing Departments to measure their suppliers’ cost structure, R&D Departments to confirm technological choices depending on their impact on costs, and Benchmarking/Marketing Departments to monitor the products on the market.
System Plus Consulting is committed to provide a high level of service:
− Delivery of reports and custom analyses with a minimum lead time.
− Results presentation and online Q&A sessions when support is needed.
− Open methodology and full confidentiality in order to maintain a trustful collaboration.
Since 2008, our partnership with YOLE Développement has allowed us to stay at the forefront of technologies and has added a market view to our reports.
