Multilayer Coating Capability

Edmund Optics (Barrington, NJ) has increased the company’s capacity to make complex coatings with more than 100 layers by adding a new 45-in. diameter Vacuum Process Technology coating chamber. The coatings can be applied to many categories of catalog parts, including polarizers, laser mirrors, short wave pass and long wave pass filters, beamsplitters, and dichroic color filters, as well as custom optics that require specialized multilayer coatings. The VPT coating chamber is equipped with two electron guns (E-guns) and planetary rotation. It also has a high-output ion gun, which produces shift-free coatings with tolerances of less than ±1 percent. The chamber can predict and execute layer termination using either quartz-crystal numbers or transmission values calculated from curve-fitting algorithms matched to the measured optical monitor values.

Low-Light CCD

e2v Technology’s (Chelmsford, England) CCD201 is a large-format 1-k × 1-k, 13-μm pixel image sensor designed for low-light, high-resolution scientific applications. The sensor claims a quantum efficiency of 95 percent with minimal induced noise. Designed for bio-science applications such as drug discovery, bio-luminescence, and fluorescence microscopy, as well as astronomy, the CCD201 is available in front- and back-illuminated formats, both of which offer sub-electron noise and a choice of electron-multiplying or traditional output. Each is capable of operating at an equivalent output noise of less than one electron at pixel rates of over 15 MHz.

X-ray Inspection

Designed as a yield enhancement system for electronics manufacture, YESTech (San Clemente, CA) has released the YTX-3000 HXR x-ray inspection system for extremely high-resolution applications. Featuring an open-tube transmission target x-ray source with an integral high-voltage power supply and computer-controlled operation, the HXR system resolves sub-micron features with zoom magnifications up to 2400×. The x-ray source is designed for minimum maintenance with an easily replaceable filament and target assembly. The 3000 HXR is available with a 4- or 5-axis sample manipulator and a 15 × 20-in. (380 x 500 mm) X-Y travel stage for samples up to 5 lbs. in weight. Full 360° rotation and 30° of tilt are available. A computer-controlled motor drive provides a wide rage of motion from ultra-slow use at high magnifications, to high speed for travel over large distances. All systems come with a control module and programmable motion for automated inspection.

Tunable Laser

Santec (Komaki, Japan) has released the TSL-510 tunable laser. Designed with many of the same features as the TSL-210V external cavity tunable laser, the TSL-510 offers a new front-panel interface and a number of improved features. The TSL-510 is a bench-top type that offers a 120-nm mode-hop-free tuning range selectable within the 1260-nm to 1680-nm wavelength region. Average optical output power is 10 mW. The laser has a 100-nm/s rapid wavelength sweep function that is particularly suitable for fiber optic component testing and material characterization. The instrument has USB and GPIB interfaces and comes with a standard LabVIEW driver. The TSL-510 is designed to meet the needs of a variety of applications, including telecom, gas sensing, spectroscopy, and material characterization.

Ball Bearings

SKF USA (Kulpsville, PA) offers self-aligning ball bearings that allow for angular misalignment of the shaft relative to the housing without affecting operation. The ball bearings gain their self-aligning capability from a design incorporating two rows of balls with a common sphere raceway in the outer ring. They are available with cylindrical or tapered bores, in bore diameters ranging from 5 mm to 130 mm.
