The multiple planetary disc option, in conjunction with new media, from Hans Weber Corp. (Olathe, KS) enable the company's machines to remove laser (and plasma) oxide scale on the longitudinal, cross and contour edges, including holes and slots, in a single pass on parts up to 0.350-inch thick and up to 1-inch thick in two passes. The multiple-action planetary discs replace the standard Scotch Bright or Spider abrasive. There are multiple small brushes with vertical media around each disc (and there are multiple discs, depending on the machine width). Also available is a new media that can be mounted in the planetary disc assemblies, which will round all part edges, including stainless-steel parts.

The planetary disc option can be added to the larger NLC and MLC (wet and dry) series machines as well as the dry TT series.

Optical filters

Stabilife optical filters from BFi Optilas (Evry, France) in collaboration with Spectra-Physics-Corion offer high throughput, steep transitions, excellent rejection and low autofluorescence. According to the company, without any need for hermetic sealing, filters constructed using Stabilife films will typically provide a field lifetime that is several orders of magnitude greater than the lifetime of filters produced using conventional film processes.

Ball Monorial—Monorail Series MB and miniature linear guideways—Series Minirail from Schneeberger Inc. (Bedford, MA) are available with in-..stock delivery time. The Minirail series is a family of robust, two-row miniature guideways made from stainless steel. An advanced ball-retainer design simplifies installation and maintenance. Four standard sizes are available: 7, 9, 12 and 15. Two accuracy grades, two preload categories and rail lengths up to 980 nm are available. Monorail BM offers running characteristics such as low pulsation, low friction values and high traveling speeds.

Beam delivery optics

CO2 laser optics from Laser Research Optics (Providence, RI) are offered in 1/2-inch to 1 1/2-inch diameter sizes in a variety of thicknesses and are available with coatings to match specific phase and polarization requirements. Featuring less than 0.2 percent total absorption, these zinc selenide optics are designed for use with 25W to 200W lasers. Available with focal lengths from 1 inch to 25 inches in 1/2-inch increments, the optics are optimized for 10.6µm radiation.
