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).

Engineers Concerned About Algae-Based Biofuel

DOE recently announced that it is awarding $78 million in stimulus money for research and development of algae-based biofuel. Yet researchers from the University of Virginia have found there are significant environmental hurdles to overcome, and propose using wastewater as a solution to some of these challenges.
