Configuring lighting for industrial vision and medical-imaging applications plays an integral role for inspection and analysis. The lighting for these applications needs to be set up at the proper angle to get the most vivid image and to obtain the highest degree of accuracy.
But illumination can be used for applications far and wide -- not just medical and industrial uses. Back in March, Catalyst Semiconductor Inc. (Sunnyvale, CA) and Texas Advanced Optoelectronic Solutions Inc. (TAOS; Plano, TX) signed a non-exclusive agreement to promote each other's products in the systems solutions they offer to their global Solid-State Illumination (SSI) customers; these customers include manufacturers of mobile phones, digital cameras, liquid crystal displays (LCDs) and automotive instrumentation. TAOS identified the automotive, consumer, industrial and medical markets as having the best growth potential for optoelectronic sensor solutions. Both companies share a major distribution channel, Future Electronics (Montreal, QC, Canada). In order to meet the system requirements of SSI, ambient light sensing (ALS) must be incorporated.
Formerly used in indicator lights, SSI has replaced conventional lighting across the board -- in traffic lights, mobile phones, digital still cameras, LCD backlights and signage. According to the U.S. Department of Energy (DOE; Washington, DC), the use of SSI technology will help decrease energy consumption by 29 percent in the next 20 years, and market revenues of SSI will reach $10 billion within the same time period.

Advanced Illumination (Rochester, VT) offers the SL6404 spotlight, which the company says combines the intensity and long-distance output of high-current LEDs with the accuracy of a structured light source. Incorporating the company's Evenlite II aiming technology, the SL6404 can be built for specific working distances and fields of view. In addition to powering options and the choice of LED wavelength, the SL6404 can be ordered with optional internal strobe, in a washdown version or a combination of the two. An M6 nut channel provides mounting convenience. The standard light comes in a 24-volt version with flying leads. It can be configured for use with Ai power supplies and strobe controllers. www.advancedillumination.com.
The FW-1000 filter wheel from Applied Scientific Instrumentation (ASI; Eugene, OR) utilizes a closed-loop DC servomotor to provide high-speed and low-vibration operation. The unit employs a high-resolution rotary encoder for positional feedback and uses memory to store programmable filter sequences and delays. Motion can be triggered by a TTL input pulse. Wheels are available to hold eight 25-millimeter, or six 32 millimeter, filters, and multiple wheels can be controlled from a single controller. Adapters are available for attachment to most microscopes. www.ASIimaging.com.
