Beam Shaper

SCHOTT North America (Elmsford, NY) offers the Beam Shaper laser technology, capable of shaping “square” light from an individual laser diode or rows of strings of laser diodes into a beam of light that has a round profile and offers homogeneous light dissemination. Two versions are available: for individual laser diodes with outputs up to 1 W, the shaper is cylindrical; for bars consisting of dozens of laser diodes with a total output of tens of watts, the unit is equipped with a paddle-shaped end that matches the geometry of the diode bar. Both versions provide an output of 90%. Wavelengths range from 400 to 1,700 nm.

Density Filters

Reynard Corp. (San Clemente, CA) provides Circular Variable Neutral Density (CVND) filters for use in optical systems to change light intensity from 100% to less than 0.1%. The filters are specified for linear optical density or transmission, may be sized to match the end-use, and are customizable in optical density gradient function, transmission gradient function, substrate type, and coating materials. The units can be supplied from 1.0 to 8” in diameter. Gradient coatings can be supplied from 45° to 360° of rotation.

Structured Light Laser

The LasirisTM PowerLine laser from StockerYale, Inc. (Salem, NH) is a line generator for industrial and scientific applications. A thermoelectrically cooled laser, the device is able to emit up to 1 W at 810 nm and 500 mW at 670 nm. Features include uniform intensity distribution for line generators; pointing stability; focus; over-voltage, reverse polarity, over-heading, and ESD protection; an optional base plate for heat dissipation; and an operating temperature of -20o to 50oC. The laser beam can be modulated by an external signal through a DB-9 connector on the back panel, and all models can operate in either CW or external modulation mode.

X-Ray Sensor

LINX from Electron Tubes, Inc. (Rockaway, NJ) is a linear x-ray sensor that can be expanded to provide an array of any required length; x-rays are detected using a scintillator and photo-diode array. Detector pitch is 1.6 mm or 0.8 mm. The unit is housed in an aluminum alloy box that is lead screened to protect the electronics from radiation damage. The device has a collimator with a graphite window so that only a narrow x-ray beam reaches the detector. Data output is in 16-bit format, and the system can be interfaced to a PC via a parallel port (EPP mode), a PCI-7300A data I/O card, or a frame grabber card.
