Quadrant Photodiode

Opto Diode (Newbury Park, CA) has introduced the SXUVPS4C, a quadrant photodiode with a 5 mm2 active area in each quadrant. The new device is the first of two new SXUV multi-element photodiodes to be introduced. The TO-5 windowless package features a 5-pin header. With light responsivity from 1 to 1000 nm and a shunt resistance of 100 Mohms, the new quadrant photodiode is ideal for 2 axes-positional-centering applications for lasers in the 13.5 nm to 200 nm wavelength range. Operating and storage temperatures range from -10 degrees C to 40 degrees C (ambient) and from -20 degrees C to 80 degrees C (in nitrogen or vacuum conditions). The maximum junction temperature is 70 degrees C and the lead-soldering temperature is 260 degrees C at 0.080 in. from the case for 10 seconds.

250W CO2 Laser

Coherent, Inc. (Santa Clara, CA) has added the new DIAMOND E-250 to its E Series CO2 laser family. The power range for the Coherent E-Series product line extends from 150W to 1000W. The new DIAMOND E-250 is a fully sealed, pulsed CO2 laser offering 250W of average power and > 750W of peak pulse power. The DIAMOND E 250 has its RF power module integrated within the same housing as the laser tube, eliminating the RF umbilical cable required in older Coherent K-series lasers as well as other suppliers with separate RF power supply units. In addition to the DIAMOND E-250, Coherent is also offering the new DIAMOND E-250i in the same advanced compact configuration with an output wavelength of 9.4 µm. The shorter wavelength is ideal for processing a number of materials such as films and plastics used in mobile devices.

IR Emitters

Laser Components (Hudson, NH) has introduced a new generation of diamond-like pulsable infrared emitters. The DLSxxxX2224 series has replaced its predecessors, 17-900 and 22-1000. Significant improvements include tighter process control, a longer life expectancy, and a broader hot spot. In particular at wavelengths above 4.5 μm the signal increased by approximately 30%. The diagram shows a sample measurement of the modulation depth in relation to the pulse frequency. This was measured using an IG26X250S4i type extended InGaAs photodiode.

Industry Roundtable: Design and PLM Software

As traditional Computer-Aided Design (CAD) software expands with more simulation capabilities and wider enterprise data management, software vendors are meeting customers’ demands with solutions that encompass the entire product development process, from initial design through end of life. In our annual poll of executives at leading CAD software companies, we learned how CAD continues to evolve, and what some of the important trends are for 2014.

Moving Magnet Voice Coil Actuators Offer Controllable Movement for High-Duty-Cycle Applications

There are two types of voice coil actuators: moving coil and moving magnet. The materials of construction are similar, since they both use rare earth magnets, steel, copper wire, and basic insulation materials. There is a tendency to want to say one type is better suited for certain applications; however, there are many different sizes and shapes of voice coil actuators, making it difficult to make blanket statements about which type of actuator works better, and where.
