Techs of the Week

A solid-state oxygen microsensor measures the potential difference (EMF) generated by two electrodes deposited on a solid oxygen-ion-conducting electrolyte and located in a known and preferably constant temperature gradient in the same ambient atmosphere. The microsensor is used for combustion systems to maintain and improve combustion efficiency levels and exhaust gas cleanliness.

Product of the Month

The N4917A optical receiver stress test set from Agilent Technologies (Santa Clara, CA) has been named PTB's Product of the Month for July. It provides repeatable conformance and characterization test results, and allows users to accurately characterize and verify standard conformance of receiver optical subassemblies and transceiver modules operating up to 12.5 Gb/s. The test set consists of the N4917A calibration and automation software; the 81490A reference transmitter for 1,310-nm and 1,550-nm single-mode wavelengths; the 81495A reference receiver; accessory kits for 10 Gb Ethernet Fibre Channel testing; the J-BERT N4903A high-performance serial BERT; and the 86100C Infiniium DCA-J.

Current Attractions

Technology for manufacturing diffraction gratings for spectrometry has not changed significantly in the past 40 years. But, according to Dr. Christoph M. Greiner of LightSmyth Technologies, that has changed thanks to deep-ultraviolet (DUV) reduction photolithography. In a feature article in the July issue of Photonics Tech Briefs, Dr. Greiner explains that for gratings, the DUV production optical stepper allows the design of more than 1,011 pixels on an individual basis. The ability to monolithically integrate multiple gratings on a single substrate using the DUV process makes it possible to integrate new functions into diffraction gratings.
