Optics Metrology News Issue 1
2015 is upon us with its opportunities and challenges. To help you with these, Optic Metrology News aim to keep you up to date with new products, applications, solutions and companies we are working with. Last year Lambda linked up with some companies to broaden its Optic Metrology product line from the hopefully familiar Zygo Fizeau interferometers and Optical Profilers. One... -
Colour capabilities of the Zygo Nexview for corrosion investigation
Researchers at Imperial College and Rolls-Royce have investigated the nature of blue corrosion areas in Ti alloys used in aerospace applications. After extensive investigation using Light Optical Microscopy (LOM) and Secondary Electron Imaging (SEI) they were able to identify the same blue area with both techniques. The LOM shows the area well but gives no surface topography, whereas because the... -
The Baumer LX series – new high-resolution CMOS cameras with up to 20 megapixel and Dual GigE
New LX series further expands the Baumer portfolio with cameras featuring high-resolution CMOSIS sensors and Dual GigE interface. First models will be available as of June. They are the ideal solution for applications with demanding requirements on high-definition quality in image acquisition at high throughput. The new LX series master such tasks with 8, 12 and 20 megapixel resolutions and the 240 MB/s bandwidth of... -
About Lock-In Amplifiers
Lock-in amplifiers are used to detect and measure very small AC signals, all the way down to a few nanovolts. Accurate measurements may be made even when the small signal is obscured by noise sources many thousands of times larger. Lock-in amplifiers use a technique known as phase-sensitive detection to single out the component of the signal at a specific... -
Vibration-Tolerant Interferometry
QPSI Technology Shrugs Off Vibration from Common Sources When image stabilisation became available on digital cameras, it vastly reduced the number of photos ruined by camera shake. The new technology eliminated the effects of common hand tremors, greatly improving image quality in many photo situations. In precision interferometric metrology a similar problem, environmental vibration, has ruined countless measurements, like the... -
Basics of Raman Spectroscopy
Laser - Creating Raman Scatter In Raman spectroscopy, it is essential to utilise a clean, narrow bandwidth laser due to the fact that the quality of the Raman peaks are directly affected by the sharpness and stability of the delivered light source. The i-Raman® spectrometer system features a patented CleanLaze® technology with a linewidth < 0.3nm when equipped with our 785nm and... -
Application Note for LN Modulators
LN Modulator is a device which converts information to signals by varying intensity and frequency of light. Capacity of transmission signal can be many tens times greater than conventional capacity by using this optical modulator. Application Note for LN Modulators -
