Laser Diodes

Alfalight (Madison, WI) has introduced the 808C laser diode series of 3.5W, 808nm devices in a 6-pin package with a 105μm/0.15 NA output fiber. They feature a lifetime of 20,000 hours. A 3W version integrates wavelength stabilization technology (WST) to offer 0.07 nm/°C wavelength stability. Additional new products include a 30W, 879nm combined power module (CPM III) with 685 μm/0.22NA output fiber connector, and a 5W, 793nm, 6-pin laser with 200 μm/0.15NA fiber.

Dual CCD Camera

Hamamatsu Photonics (Bridgewater, NJ) has introduced the ORCAD2, a dual CCD camera that can capture simultaneous dual wavelength or multiple focal plane images. Each CCD captures a 1280 (H) x 960 (V) pixels field of view, and each CCD has independent exposure and gain settings, making it suitable for FRET and ratio imaging applications. One of the CCDs is adjustable via software to compensate for vertical, horizontal, and Z-axis registration. Each optical block can be adjusted for multiple objective choices as well. When the optical block is inserted into the camera, the position of the moveable CCD is automatically adjusted for the optical setup. It also features high sensitivity and low noise, vacuum-sealed chamber technology, and wide dynamic range. An IEEE1394b interface, 12-bit A/D converter, and various external trigger modes are also included.

Purified Steam Generator

RASIRC® (San Diego,CA) has introduced the Steamer '02, which generates purified steam from de-ionized water for semiconductor, MEMS, solar, and optical device applications. It features additional control loop for the heated steam process line between the Steamer and the tool, integrated flow meter, reduced footprint and simplified installation with the addition of an internal three-way valve, and improved tracking of flow rate and energy use with an updated user interface. The Steamer ’02 allows the use of de-ionized water for critical processes by removing volatiles, ionic contaminants, and other impurities from steam.

Laser Fluorescence Filters

Semrock (Rochester, NY) has announced a triple-band filter set for three-color microscopy, LF405/488/594-A, consists of an excitation filter, a beamsplitter, and an emission filter for simultaneous illumination with 405, 488, and 594 nm laser lines. A complete single-band set, LF594-A, optimized for the orange laser, is also available, and includes a laser-optimized dichroic beamsplitter, Di01-R594, with excellent edge steepness and precision optical flatness. The new EdgeBasic™ BLP01-594R long-wave-pass filter is designed for fluorescence imaging as well as Raman spectroscopy. These filters were optimized for use with the Cobolt Mambo™ 594-nm orange laser, which is available at up to 100 mW CW output power.

Avalanche Photodiode Receiver

Voxtel (Beaverton, OR) has introduced an avalanche photodiode (APD) receiver with 1-GHz bandwidth and a large 200-μm diameter optical area. The RIP1-NJAC APD photoreceiver integrates the low-excess-noise SCM-APD with a low-noise transimpedance amplifier (TIA). It offers a maximum responsivity over 50 A/W at 1550 nm, with operating gain up to 50. A single-stage thermoelectric cooler is included to eliminate temperature-induced gain variation. An optional fiber pigtail is available.

Logarithmic Sensor

New Imaging Technologies (Evry, France) has introduced the MD1-10-B logarithmic sensor, which uses an array of photodiodes operated in photovoltaic mode. In most logarithmic imager designs, linear photo current passes through a MOS transistor whose exponential characteristic transforms photo current into a logarithmic-like voltage output signal. In NIT’s MAGIC approach, the array of photodiodes is operated in photovoltaic mode and the open-circuit voltage across the p/n junction is proportional to the exact and pure logarithmic value of the incident light intensity. When equipped with the sensor, the MCD1-10-BW analog camera modules provide dynamic range performance greater than 120 dB.

EBTN LCDs

Lumex (Palatine, IL) has introduced the InfoVue EBTN (Enhanced Background Twisted Nematic) family of custom negative image TN LCD technology. The LCDs offer a contrast ratio of 300 to 1, and are RoHS compliant. They are available in sizes ranging from 1.0 in2 to 5 in2. Sharp, crisp negative images can be displayed using any color backlight.
