Chromasens Intros Coaxial Modules for LED Linescan Systems
Konstanz, Germany — Chromasens is expanding its CORONA II LED linescan illumination family with two new coaxial modules to accom- modate inspection of highly reflective surfaces, such as wafers, metal sur- faces, connectors, liquid crystals, and glass.
Offered in bright field and dark
field versions, the new CORONA II coaxial modules come in lengths up to 26.7 in. (68 cm) to enable inspec- tion of larger objects. Both have a high-quality, antireflective coating and ultrathin diffuser glass to reduce
or completely eliminate ghost images often captured when imaging shiny objects, or where the area of inspec- tion is obscured by shadows from its surroundings. While linescan cameras require

only a thin line of light to serve as illumination, it is mission-critical that the light source be as intense as possible with precise uniformity to avoid chromatic deviations. To achieve this on reflective surfaces, CORONA II coaxial illumination is diffused by a beamsplitter so that the light has no discernable directionali-
ty. Shadows are eliminated and the effects of specular reflection are sig- nificantly reduced. Chromasens’ bright field coaxial
module’s approach is based on the use of a perpendicular camera view. Light is deflected downward onto the imaging plane by a 50 percent beam- splitter, which also permits light from the object to be collected by the camera above. The coaxial path fol- lowed by the light results in a uni- form, bright, field reflection directed along the lens axis and onto the imaging plane. The only interrup- tions of the bright field are the details present on the surface of the mirror. The dark field approach is
designed to get light inside of deep objects — for instance, the inspection of pin counts on automotive plug con- nectors installed within a housing. Dark field illumination is required in most inspection tasks utilizing tele- centric lenses. Here, the coaxial light source will direct light rays towards the lens that then redirects the light towards the object and is reflected back through the lens towards a cam- era, creating diffused, uniform illu-
mination. Contact: Chromasens GmbH,

SCHURTER Unveils UL Approved 400 VDC Couplers
Santa Rosa, CA — SCHURTER has introduced its newest connectors, UL-approved 400 VDC couplers, according to the IEC TS 62735 stan- dard. Manufacturers of PDUs and other equipment for data centers have long demanded a safe and reli- able, standardized solution for DC power architecture. SCHURTER is also offering its
4751 series, IEC 60320-style F out- lets for 2-, 4- or 6-pack configura- tions. The prewired outlets are designed to provide enhanced fea- tures for increased functionality, ease of assembly and offer a tamper- resistant blind cover, series BC320, to manage system loads in PDUs and UPS applications. The 4751 series is certified by VDE and CCC for 10A at 250 VAC. They are cURus-approved for 15A at 250 VAC. The company also offers various
outlets with integrated light pipes, 6600-5, 4797-5, style F and J. The integrated light pipes channel light from LEDs on the PCB to the front of the connector, serving operational or other functional status indication. Outlets with IDC terminals for quick assembly, 6610-5 and 4710-5, are
also available. Contact: SCHURTER, Inc.,
