Opto Products Semelab Opto-Electronic Components, Modules and Solutions OPTO CHIP DESIGN WAFER PROCESSING A Proven Record The Semelab Group has been a leading provider of high-end, innovative electronic solutions since 1974. A diverse, worldwide customer base benefits from our design innovation, our manufacturing strength, and our total commitment to quality. Our key strengths, gained through experience, lie in our ability to advise and expertly interpret your requirements. This attention to detail is how we are able to process the required silicon and identify the most suitable and cost-effective packaging and die solutions for your particular individual needs. The enviable reputation we enjoy in the industry comes from working closely alongside our customers in order to acquire an in-depth market knowledge and a genuine understanding of exactly what you require from us. In-house Fab, Assembly, Test and Engineering Semelab has it's own ISO 9000 approved wafer fab at Glenrothes in Scotland called Semefab, and performs assembly, screening and test operations at the company's facility in Lutterworth, England. All aspects of design, processing, testing, packaging and qualification take place within the Semelab Group, thereby ensuring complete control over quality and reliability. Semelab holds quality approvals for processes and products from major standards organisations, including ISO, ESA (European Space Agency), DSCC, and CECC amongst many others. Applications Our standard and custom designed sensors are used in a wide range of applications; such as: • • • • • • • • • • • Exhaust gas monitoring Document security Industrial process control Radiation detection and environmental monitoring Medical analysis equipment Ride height sensing Linear encoder devices Vending machine mixture control Helicopter rotor vibration monitoring Tank turret control Head-up-Displays PACKAGING Standard PiN Photodiodes The SMP series is an established standard range of Silicon PiN Photodiodes available in a selection of flexible package options. Active areas of between 0.62mm to 100mm are available to suit various applications, and a range of packages and optical filters are readily available. Hybrid Photodetectors Semelab offers a comprehensive range of standard hybrid detectors, including an integral operational amplifier and associated feedback components. Our hybrid devices providing a voltage output which is proportional to light incident on the detector and have the advantage of minimising noise pick-up and reducing the need for external circuitry. Gain and frequency response can be selected for your particular application, and standard UV, daylight and IR filtering windows are fitted as integral options. Self-Monitoring Emitters To complement our hybrid detectors, we also produce a range of self-monitoring LEDs in a variety of colours. To enable accurate output control, these feature an internal photodiode. Alternative colours are available on request to match your individual requirements, and custom LED arrays can be designed to suit your specific applications. ASICs Semefab has been manufacturing and supplying ASICs for more than 10 years into consumer, industrial and the automotive markets for a wide variety of applications. Semefab can help to define the ASIC specification and/or the appropriate partitioning of your system if in-house expertise is unavailable. Contact Semelab Sales on +44 (0)1455-55-65-65 [email protected] STANDARD PARTS CUSTOM PARTS ASIC devices Our most popular device types include: • Photo-ASICs for monitoring light levels with photopic filtering as a replacement for Cadmium Sulphide cells • Street lighting applications known as PECUs, for replacement of CdS cells in line with ROHS European regulations • Visible Light Detectors • Optical Smoke detectors • Custom Photo-ASICs – meeting all of your custom requirements for layout, manufacture, test and packaging Our investment in new technologies continues with the development of micro machines and nano-systems for future state of the art sensors. Foundry Semefab operates a flexible 100mm/150mm Foundry operation supporting MEMS, CMOS, ASIC and Discrete Technologies. A capable legacy of process development, induction and fabrication dating back to 1986 is testimony to the organisation’s cost-effectiveness and resilience. Semefab’s Foundry is a privately owned, profitable organisation with a diverse process technologies portfolio. With stable financial performance Semefab is the industry’s low-risk, longterm supply chain foundry partner. Having a diverse process portfolio and a long successful history of process development and induction, Semefab is the ideal foundry partner to integrate different technologies on the same silicon substrate. Semefab also has a proven capability of inducting customer technologies. WIDE RANGE OF APPLICATIONS New Developments Semelab offer a complete design and manufacturing service. We are able to customise component parts to meet our customers’ specific applications. All development of new Semelab products is undertaken in close collaboration with customers, and always bearing in mind their specific requirements. On numerous occasions, we have developed new processes to meet customer’s specifications. Semelab are proud to be involved in numerous Europeanfunded projects, working alongside a number of leading research organisations and Universities for the development of leading edge technologies. At Semelab, whatever the challenge, we have the ability to meet it.

The dynamic range is determined by the external resistor and power supply. (e.g. 5V across a 10K resistor gives a range of 0 to 250 Lux but can be raised to 1000 Lux with a 1K resistor). The internal dark current cancellation enables high accuracy over the full temperature range, even at low light levels. The devices can be supplied in probed wafer form, probed sawn wafer form, or packaged in LED-style or surface mount packages. Street lighting applications, also known as PECUs, require daylight/night-time transition recognition whether it is centralised or localised on the street lights themselves. These new devices have been developed specifically for replacement of CdS cells in line with ROHS European regulations. This type of daylight monitoring is used in motion-detection security lighting and many other applications. Visible Light Detectors (412101, 412102, 413101) These devices show excellent uniformity and linearity of performance with various types of light including ambient, Tungsten Filament, fluorescent and LED lights.
