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.
