The compact 200mm focal length spectrometer can be supplied with various gratings to spread optimization over the entire 30nm to 550nm wavelength range; an advantage allowed by the optical design. In combination with windowless, sensitive, cooled, scientific grade CCD detectors, adjustable slits, and f/4.5, the McPherson Model 234/302 provides fast, sensitive data collection.
Extreme and vacuum ultraviolet radiation and emission spectra can be analyzed with sub- nanometer spectral resolution. Adjustable slit width provides for best light throughput and for better spectral resolution to resolve closely spaced spectral lines.
McPherson Unveils UV Spectrometer for 120- 900nm Applications
The firm is marketing its vacuum ultraviolet spectrometer, model 234/302, which is claimed to offer improved efficiency over a wide wavelength range.
The firm, based in Chelmsford, Massachusetts, designs and builds tools to measure frequency and intensity of light wavelengths / rays with good spectral resolution over a wide free range. McPherson ‘s instruments can be used for measurement of wavelengths through the X Ray, Vacuum, UV, Visible and Infrared (IR, including MWIR and LWIR) regions.
The instrument should be suited to the measurement of different emission wavelengths in III-V semiconductors, for example gallium arsenide (GaAs) quantum wells.
McPherson is marketing its vacuum ultraviolet spectrometer, Model 234/302, which is claimed to offer improved efficiency over a wide wavelength range (120nm to 900nm). In addition, platinum coated gratings can be used at windowless wavelengths, shorter than 120 nanometers (>10eV.)
Tunability of the installed grating to longer or shorter wavelengths provides means to collect different simultaneous wavelength swaths for general-purpose spectroscopy, plasma physics, and process monitoring without compromising resolution or signal strength.
The newly introduced Platinum coated optics improve utility of the Model 234/302 vacuum ultraviolet spectrometer system. Furnished with spectral calibration certificate, the McPherson spectrometer is available with standard light sources, reflective condenser optics, and vacuum differential sections.
Strasbaugh Hires E-Dot To Improve Services in Taiwan
The provider of wafer polishing and grinding tools is improving its support services to its Taiwanese customers.
Strasbaugh, a provider of equipment and tools for advanced chemical mechanical planarization (CMP), prime wafer polishing, and grinding equipment for device and wafer manufacturing has engaged the services of E-Dot Technology.
E-Dot is a CMP service and support company headquartered in the Hsinchu Industrial Park and will represent Strasbaugh by providing service and support to Strasbaugh’s Taiwan-based customers.
“E-Dot Technology is well regarded for their technical support services and are a welcome addition to the Strasbaugh team,” says Bob Roberts, Executive Director, Advanced CMP
