Fiber-coupled diodes
High-power laser diodes for materials processing can deliver up to 2000 W of optical power to the workpiece through fibers of 1-mm diameter or up to 4000 W through fibers of 1.5-mm diameter. By using smaller fibers with higher optical powers, the lasers deliver a reduced spot size while increasing working distances, allowing key-hole welding as well as metal cutting and brazing at higher powers.

Laser illuminator
Laserflash is a high-power laser designed as an illumination source for machine-vision applications. It produces up to 130 W at 810 nm and has a working distance of several hundred meters with a selectable field angle. Its narrow spectral band allows the machine vision to exclude ambient light interference by using filters in the camera system. It complies with Class 1 laser standards. Pulse length is adjustable from 0.1 to 1000 µs, with a repetition rate from a single pulse to 100 KHz.

OEM photodiode
The SD150-14-006 is a new silicon PIN photodiode for OEM optical-communications applications. The device is designed for VFIR links, IrDA-compatible transceivers in cameras, portable peripherals, and data storage devices. The proprietary design enables high-speed operation at a bias voltage of 2.5 V, allowing compatibility with battery-powered devices. An active-area diameter of 2.3 mm2 simplifies optical alignment. Signal tailing is alleviated.

Large-format image guides
Large-format, fiberoptic image guides are available with 8.0 x 8.0-mm and 11.5 x 8.0-mm active areas. Images can be obtained by adding off-the-shelf lenses and in combination with CCD cameras to view critical environments otherwise hostile to video cameras. The guides are equipped with end-tip fittings and outer protection sheaths that can be customized.

TEC fibers
TEC fiber (Thermally-diffusion Expand Core) is designed to reduce coupling loss induced by optical alignment error between two different SM fiber cores and the laser diode and during optical assembly. A patented NTT Micro Burner Method is used to more than double the size of the fiber while maintaining low loss. TEC fibers are available with 20 or 30 µm of expanded core on a 1.5-m cable.

Portable chillers
New 20- to 30-hp PS Series portable chillers have tandem hermetic scroll compressors with Smart Cool technology. This allows one compressor to shut off when process water temperature reaches the desired set point. The chillers have a stainless-steel, copper-brazed plate evaporator, nonferrous process piping, and an 80-gallon reservoir. Temperature control is accurate to ±1°F, with an operating range of 30°F to 65°F. Air or water-cooled versions are available.

Automated laser-weld fiber-attach station
The FAST 30 is a laser-weld machine incorporating automated fiber and ferrule feed into the photonic package, providing fully automated fiber alignment and laser welding. Total cycle times are typically four minutes, roughly half the time of alternative automation machines. The machines support laser welding, epoxy dispense/cure, and solder processes using a standard station base and software.
Axsys Technologies, Rocky Hill, CT

Light pipes
A new series of light pipes is available in sizes ranging from micro to 150 mm. Light pipes are used to couple light from one aperture shape to another and are available in designs, including rectangular, round, and tapered. Materials in use are fused silica, glass, and silicon.
Argyle International, Princeton, NJ

EtherNet industrial protocol
The Ethernet Industrial Protocol (EtherNet IP) has been added to the In-Sight family of networkable vision sensors. This enables direct, real-time communications between vision sensors and other factory automation devices over a single Ethernet wire. Customers have the ability to link multiple vision sensors together and remotely monitor vision activity throughout the manufacturing process.
Cognex, Natick, MA

Solid-state 460-nm blue laser
The new Sapphire 460-10 incorporates a proprietary, optically pumped semiconductor-laser (OPSL) technology. OPSL technology uses optical energy to drive laser emissions, compared to conventional VCSELs driven by electric current, for higher power. The laser is designed to enable digital imaging systems, inspection systems, and bioinstrumentation. The sapphire laser is 90% smaller, consumes 98% less power, and dissipates 98% less heat than a comparable air-cooled argon-ion laser.

Color meter
The HCT-99 color meter measures illuminance, correlated color temperature, and the (x,y)/(u,v) chromaticity coordinates, all with one meter. The compact unit includes two separate detectors for xshort and xlong functions and an f1'<4% spectral match of the V(λ) detector, which exceeds the DIN 5032 classification for class B lightmeters.
Gigahertz-Optik, Newburyport, MA

VCSEL arrays
The STABILAZE 850-nm vertical-cavity surface-emitting laser (VCSEL) arrays are stabilized at the wafer level, eliminating concern about parametric shifts of the output caused by temperature and current. Uniformity of characteristics such as threshold, slope efficiency, and resistance improve laser performance.
