Illuminator provides regulated light
Model 21 dc fiberoptic illuminator is a regulated light source for use where light output stability is necessary. The 150-W, CE marked halogen illuminator delivers intense, stable, cool illumination to applications when coupled with a company's standard fiberoptic component. The regulated light output is stable to ±1%, eliminating output fluctuations due to line-voltage variations. A 0%–100% LED light intensity control indicates when to change the halogen lamp. Other features include a power-on LED indicator light, an auto-switching input-voltage regulator that accepts 110–220 Vac, and a 9-pin DIN connector that supports a remote intensity control using a 0–5-Vdc supply. The rugged aluminum extruded housing is coated with a durable finish. A T-slot runs the length of both sides of the housing for integrated mounting capabilities using 1/4-20 screws. Accessories include a flexible positioning handle, mounting brackets, and an IR filter insert. StockerYale Inc., Salem, NH; www.stockeryale.com.

Frame grabber runs 32 bits
PC2-Vision analog frame grabber serves the 32-bit PCI bus and is 5- and 3.3-V PCI compliant. Its acquisition circuitry interfaces with a variety of industrial cameras, including standard (RS-170 and CCIR), nonstandard (progressive scan), RGB and monochrome, and dual-channel analog cameras. Its six camera connections support simultaneous acquisition from up to six monochrome or two RGB cameras, making related images available at the same time. An RS-232 serial port is available on both 3M MDR-36 camera connectors. Simultaneous acquisitions are supported through a frame-delay mode, which allows concurrent captures from all six inputs. A 40-MHz triple-channel, eight-bit analog-to-digital converter offers gain and offset controls to match the camera's video voltage level. Software support includes the company's Imaging Foundation Class, MVTools, Sherlock, and WiT. Coreco Imaging, St. Laurent, QC, Canada; www.imaging.com.

Vision library adds functions Imaging and Vision Library helps simplify program development and decreases product time to market. It is a high-level programming library for image processing and analysis that is compatible with all company FlashBus and FlashPoint frame grabbers, including FlashBus MX and FlashBus DX with Camera Link. The software package enables OEMs to produce imaging and analysis applications without the need for third-party software. Supported by Windows 95/98/Me/NT/2000/XP, the library provides core machine-vision and imaging routines in a conventional C-callable interface. Other routines cover image acquisition, image-buffer management and manipulation, image processing, graphic overlaying, file I/O, calibration and measurement, blob analysis, normalized gray-scale correlation pattern matching, rationally invariant pattern matching, PerfectFocus image blending, and various mathematical subroutines.

Software library supports Linux XCLIB library supports the Linux 2.4.8 operating system and later kernels, as well as Intel (x86) platforms. It allows programmers to generate custom machine-vision, motion-analysis, and medical-imaging applications. The software provides the same application program interface as XCLIB for Windows, permitting programmers to move from one operating system to another. It also supports all versions and options of the company's PIXCI imaging boards and NTSC, RS-170, CCIR, PAL, and common area-scan or linescan digital cameras with up to 4k x 4k-pixel resolution, up to 14 bits per pixel (gray), up to 42 bits per pixel (color), and at rates up to 16,000 frames/s. Full-resolution images are processed at full video rate. EPIX Inc., Buffalo Grove, IL; www.epixinc.com.

Rotary tables offer direct drive ADRT Series of direct-drive rotary stages provide precision angular positioning and velocity control. They use a slotless, ironless design that achieves smooth performance and ease of tuning when compared to competitive iron core and variable-reluctance motor designs. The brushless direct-drive servo means that there are no brushes to wear, no gear trains to maintain, and high accelerations and speeds. Low inertia and zero backlash make the rotary stages well suited for applications requiring frequent directional changes. When coupled with the company's MXH series resolution multipliers, resolution can be as fine as 0.12 arc sec. Motor and rotary encoder are directly coupled to a common shaft. The absence of gear trains and mechanical couplings produces no position errors caused by hysteresis, windup, or backlash. Aerotech Inc., Pittsburgh, PA; www.aerotech.com.
