Illuminators save space For machine-vision applications where the light source is mounted into a machine or robot arm, Dolan-Jenner redesigned the Fiber-Lite A-240. Available in either a dual- or low-profile module, the A-240 features two power supplies on separate boards housed in the same enclosure. Each power supply on the dual model provides energy to one remote lamp head, giving two functionally separate illuminators in one package. Delivering lamp color temperature of 3200 K, with a lamp output of 400,000 fc, the A-240 dual- and low-profile models hold up to three filters. Dolan-Jenner,Lawrence, MA; (800) 833-4237.
Lenses image in the ultraviolet Quartz lenses for imaging in the ultraviolet spectrum are available in focal lengths of 25 and 75 mm. In the 25-mm length, the UV2528 is a 16-mm imager with adjustable focus and a fixed aperture of f/2.8. The UV2528B has the same features but includes an adjustable iris. Both lenses are available in C-mount form. With a 78-mm focal length, the UV8040B features an adjustable iris and focus and a fixed aperture of f/3.8. In C-mount form, the lens covers an 18-mm imager. If the C-mount is removed, the lens is transformed into a T-mount version capable of covering 35-mm film.

Linescan imaging system targets web inspection Used for detecting high-contrast defects in continually processed materials, the Web Ranger 1000 identifies defects just 0.005 in. in size at speeds of up to 1200 ft/min. The PC-based system provides real-time flaw mapping, flaw image display, defect classification, web imaging, trend analysis, statistical compilation, report generation, and data archiving. At the heart of the Web Ranger is the Opsis 5150ALC smart camera. Because the image-processing and analysis capabilities are in the camera, the Web Ranger 1000 does not require frame grabbers or image-processing engines. Networked via Ethernet for the synchronized image capture of 100% of the material surface area, the camera provides 5150-pixel resolution. Price ranges from $40,000 to $100,000, based upon the application and number of cameras required. Wintriss Engineering,San Diego; CA (800) 550-7300.
