Advances in Manufacturing Fiber Optic Gyroscopes

Since it was first proposed in 1975, the fiber optic gyroscope (FOG) has steadily improved in performance and manufacturability. Now a mainstream, high-volume manufactured product with performance approaching Ring Laser Gyros (RLG), FOGs offer substantial advantages over competitive technologies in terms of reliability, cost, and complexity. Optical fiber splicing and related processes are at the core of this achievement.

Beyond Smart Vision

Many Higher-End Vision Projects Require Capabilities Not Built Into Smart Vision Systems With the proliferation of smart vision (SV) cameras and platforms it is understandable that automation engineers begin to define vision technology capabilities based on the performance and features of these popular and easy to implement products. Although they are effective for addressing a broad range of common vision applications and requirements, there are compromises made to make SV products easy to use and less costly, the obvious being reduced vision processing and performance capabilities.

Product of the Month: Non-Contact Laser Beam Monitoring System

Ophir Photonics (North Logan, UT) announced the newest version of BeamWatch™, a non-contact, focus spot size and position monitor for very high power YAG and fiber lasers used in material processing applications. Because there is no contact with the laser beam, the system has no power restriction and has been successfully tested on high power lasers up to 100kW.

Multispectral Photodiode Array

PIXELTEQ (Largo, FL) has released its PixelSensor™ 8-band multispectral photodiode array, packing eight wavelength-selective photodiodes into a compact 9mm square sensor. The PixelSensor photodiode splits the visible spectrum into eight discrete color bands. Its standard 20-pin LCC package can be surface or socket mounted. Common cathode operation provides low noise and fast response time. Customized OEM versions of PixelSensor are also available with user-defined spectral bands. Using PIXELTEQ’s exclusive micro-patterned optical filter technology, narrowband filters deliver improved sensitivity and contrast for multispectral applications from portable color monitors to industrial and scientific instruments.

Configurable Fiber Laser Workstation

IPG Photonics Corporation (Oxford, MA) has introduced the IX-200-F, an advanced fiber laser micromachining system for general purpose, R&D and batch-scale production applications. IPG’s IX-200-F is a fully enclosed and interlocked CDRH Class 1 system, configurable with a wide range of IPG fiber lasers and fully integrated with the system operating hardware and software. The IX-200-F features a high-resolution, high-performance microscope vision system that provides a continuous zoom range from 38X to 880X for sub-micron automated part alignment and inspection. The selection of IPG Fiber lasers currently supported on the IX-200-F includes pulsed IR to >500 watts and pulsed green up to 50 watts as well as UV lasers. Users may select ablation or thermal cutting and scanning or fixed beam delivery configurations.

20-Element Photodiode

Opto Diode (Newbury Park, CA) a division of ITW, has announced the second in the AXUV series of multi-element photodiodes. The new 20-element AXUV20ELG features a 22-pin, dual in-line package with 100 percent internal quantum efficiency (QE). Bolometry, the measurement of minute amounts of radiant energy, is a key application for this highly sensitive photodiode. The device is also ideal for electron detection, providing EUV-UV and UV-VIS-NIR photon responsivity (measured in amperes per watt).
