High-Speed Megapixel Camera

Photron (San Diego, CA) has developed a new imaging system, the Fastcam SA5, which delivers 7,500 fps at 1024 × 1000 megapixel resolution. The camera features a 12-bit monochrome (36-bit RGB color) sensor with twenty micron square pixels, delivering color fidelity and dynamic range. This standalone, one-piece system has an ISO/ASA of 6400 as tested against ISO 12232. The Fastcam SA5 with 1-microsecond global shuttering features a 5-inch LCD screen and is available in three memory configurations: 8 GB (up to .75 sec record time at 7,500 fps and full resolution); 16 GB (up to 1.49 sec at 7,500 fps and full resolution); 32 GB (up to 2.98 sec at 7,500 fps, 1K × 1K). Applications include PIV, inkjet, combustion, fluid dynamics, cavitation, materials research, and aerospace.

Silica Fiber Bundles for Spectrometer Systems

CeramOptec (East Longmeadow, MA) has increased the temperature spec on its drop-in replacement silica fiber bundles for spectrometer systems. Applications with unusually high or low temperatures can use these fibers to work at a temperature range of -190°C to 600°C. CeramOptec uses a patented PCVD process to create high-grade specialty fibers with a wide range of profiles and dopants, numerical apertures from 0.06 to 0.66, and high radiation resistance levels.

Near-Infrared Bandpass Filters

A new series of bandpass filters from Semrock (Rochester, NY) can be applied to the near-infrared wavelength range. These hard-coated filters are keyed to popular laser lines in the 1500-1600nm region. Applications include use as laser source clean-up filters and detection filters that pass particular laser wavelengths and virtually eliminate background over the full InGaAs detector range (850-1750nm). They are optimized for “retina-safe” lasers in the 1.5μm wavelength range.

Q-Switched 800-Watt DPSS YAG Laser

Lee Laser (Orlando, FL) has developed a new, 800-Watt CW Nd:YAG laser that is capable of Q-switched performance in excess of 600 watts average output power at a 10-kHz pulse rate. The short pulse width capability is less than 70ns at 10 kHz without risk of damage to the internal optical elements. Pulse instability less than 8 percent peak-peak has been demonstrated. The laser’s electrical power consumption is 10 kW. Applications include deep marking and engraving, cutting of hard materials, flat-panel display (FPD) manufacture, and laser patterning for LCD manufacture.

3-Watt RGB LEDs

Lumex (Palatine, IL) has introduced the 3-Watt TitanBrite™ RGB, a square-shaped LED with dimensions of 10mm x 10mm. It can result in 30% cost savings as well as a 70% real estate savings compared to the use of individual red, green, and blue packages. Applications include electronic signage, industrial controls, safety/security lighting, and graphic backlighting. They are RoHS-compliant and contain three individual 1-Watt dies in red (636nm), green (525nm), and blue (470nm).

Using Micro OTDRs to Test Fiber Optic Networks

Uses for traditional optical time domain reflectometers, or “OTDRs” include the certification and troubleshooting of very long-haul fiber optic networks such as campus and metro networks. In many LAN, WAN or FTTH environments, however, fiber links are relatively short and, therefore, usually operate over multimode fiber cables at wavelengths of 850nm and 1300nm. A new generation of “Micro OTDR” is ideally suited for this application, which typically has a maximum range of about 25 miles.

Reinventing Disease Detection and Diagnosis

As devices for disease detection and diagnosis become more advanced, they also are becoming smaller. Next-generation technologies for faster detection of diseases such as cardiovascular disease, melanoma, and breast cancer are handheld devices that are easy to use, portable, and more accurate than many of the currently available diagnostic tools. As the following examples illustrate, immediate diagnosis and detection of life-threatening diseases may soon be held in the palm of your hand.
