Galvanometer Mirrors

Reynard Corporation (San Clemente, CA) has released high precision coatings Galvanometer mirrors for laser system applications such as scanners, bar code readers, sweeping remote sensors, marking systems, and laser light shows. A mirror is modulated on its centered axis, causing a static laser beam to scan in a one-dimensional orientation. Adding a second Galvo mirror allows for scanning in two dimensions. The Galvo mirror coatings can achieve reflectivity of greater than 99.9% and are able to withstand the most rigid durability requirements per military specifications, including temperature/humidity and salt fog requirements per MIL-C-48497A.

Optical Edge Filters

Semrock (Rochester, NY) has introduced optical edge filters for Raman spectroscopy and fluorescence imaging. The EdgeBasicTM long-wave-pass filters are hard-coated optical filters that have high transmission of 98% typically, and laser-line blocking with an optical density greater than 6. The filters have an edge steepness that is tailored for cost-sensitive, application-specific Raman systems that do not require measurement of the smallest possible Raman shifts, as well as for sensitive fluorescence imaging systems that demand maximum signal capture.

LED-Based Backlights

Global Lighting Technologies (Brecksville, OH) has introduced LED-based high-brightness backlights that offer thinness down to 0.4 mm for backlighting LCDs in consumer electronics products such as the keypads/keyboards used in mobile phones, laptops, and desktop PCs. The BLUs offer the thinness of electroluminescent (EL) backlighting, but with the advantages of advanced LEDs and with the superior light extraction provided by MicroLensTM molded light guides. Backlight assemblies less than 1mm high utilizing light guides as thin as 0.4mm or less are available.
