Product of the Month: Optical Receiver Stress Test Set

Agilent Technologies (Santa Clara, CA) has introduced the N4917A optical receiver stress test set to provide repeatable conformance and characterization test results. The design 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 provides the calibrated injection of optical modulation amplitude (OMA), extinction ratio (ER), and vertical eye closure penalty (VECP) through automation software controls.

Fiber Optical Switches

Laser Components IG (Hudson, NH) has introduced a series of fiber optical switches with core diameters of up to 600 μm. The "mol 1×N" and "mol 2×N" feature switching times of two milliseconds and low signal loss (less than 0.5 dB). The switches are available in various configurations, and come with or without a connector in compact housings, table housings, or 19" insertions.

LED Backlighting

CI Lumen Industries (Hauppauge, NY) has introduced a light-emitting-diode (LED) backlighting solution for display panels. The technology, applicable for military or industrial end-uses, conserves power, features heat-relevant elevated brightness levels, and may be applied to LCD panels produced by other manufacturers. Developed for hi-bright panels requiring brightness levels of 800 nits or more, the technology can be utilized on LEDs ranging from 5 to 19", and hibrighted to 800 to 1,300 nits.

Diode Laser

Point Source (Hamble, UK) offers a 20-mW blue diode laser with a TEM00 true Gaussian beam, a higher power version of their range of iFLEX2000TM fiber-coupled lasers. The laser beam conditioning is performed using a single mode fiber, reducing beam astigmatism and spatial noise. The device employs a forward closed loop power control that resists optical feedback. Short-term amplitude noise is reduced and the stability of output is augmented. Applications include biomedical fluorescence imaging and optical media.

Raman Spectrometer

The SE1000 Raman spectrometer from Mesophotonics (Southampton, UK) allows users to perform non-invasive, non-destructive analysis of materials with no sample preparation. The technique reports information on the molecular structure, identifying the material under scrutiny. It performs Surface-Enhanced Raman Spectroscopy (SERS) analysis on low concentrations of material by deposition onto the company's Klarite® SERS substrates.

CCD Cameras

Lumenera Corp. (Ottawa, Canada) released the Lm family of mini-CCD USB 2.0 cameras for industrial markets. The Lm075, Lm135, and Lm165 function in low light conditions and where space is restricted. The cameras measure 44 × 44 × 56 mm, have fast frame at VGA through megapixel resolution, and include industrial locking USB and GPI/O connectors, eight mounting points, electronic global shutter (for high speed objects), and on-board processing and sensitivity for image quality. Higher frame rates are available at lower resolution, with full sub-window control and live focusing models.
