Kyoto, Japan (PRWEB UK) 9 April 2015
Shimadzu Corporation launches compact monochromator system package (SPG-120-REV) for high speed, high accuracy optical spectrometry for applications including in-line inspection of flat panel displays, monitoring vacuum evaporation of thin films, and evaluation of spectral characteristics of cameras.
The innovative Shimadzu Corporation SPG-120-REV series monochromator system achieves wavelength changes ten times faster than conventional models by directly driving a grating with a stepping motor, thereby reducing measurement times by 50%. The compactness and software control of the SPG-120-REV system offers a wide range of applications including two dimensional spectral mapping of solar cell materials and optical devices. The system will be exhibited at Photonix 2015, April 8-10, 2015, at Tokyo Big Sight.
Monochromator systems for optical spectroscopy—consisting of a diffraction grating, monochromatic light source, and an optical detector—are used to analyze luminescent, reflectance or transmission spectra of materials and devices such as LEDs. The spectra yield important information about the quality and possible existence of defects in materials and devices. Hence, monochromator based spectroscopy, and small spectroscopy systems manufactured by Shimadzu, are used widely in production lines of quality control of flat panel displays, monitoring dry etching processes of semiconductors, and thin film evaporation systems.
The Shimadzu Corporation SPG-120-REV monochromator system was developed in response to strong demands from researchers and manufacturers for compact, high speed, accurate, and highly reproducible grating-based spectroscopy systems.
Notably, the SPG-120-REV monochromator system is able to accurately and reproducibly move from 200 nm to 900 nm in just two seconds. This speed and accuracy were realized by attaching the grating directly to the stepping motor that is used to move the grating to change optical wavelengths.
This feature of the SPG-120-REV will improve the throughput for applications that require measurements of large numbers of samples; multi-wavelength analysis of individual samples; and two dimensional mapping of the surfaces of materials and devices.
Furthermore, these features of the SPG-120-REV monochromator system are expected to open up new applications such as in-line inspection of food.
The SPG-120-REV monochromator system will be available as a ‘package’ of the individual components required for monochromator based optical spectroscopy.
-The 5 phase stepping motor with the high reduction ratio harmonic drive gearing enables high-speed wavelength positioning speed (500nm/s) that is 10 times that of conventional models.
-Move 200 nm to 900 nm in just 2 seconds.
-When the system is configured with an appropriate detector and amplifier (wavelength range 300nm to 900nm at a pitch of 10nm) then the measurement time is reduced by 50% compared with conventional models using ‘sine bar’ control of the grating.
-The 5 phase stepping motor with the high slowdown ratio gear enables high durability for repeated wavelength positioning, being 5 times more robust than conventional models using sine bar control.
-The wavelength of the monochromator is stable even if wavelength movement is repeated. Speed and efficiency while reducing human errors in the analysis workflow.
-The monochromator unit is compact with a total area of only 100 mm wide and 187 long.
The xenon lamp SPG-120-REV monochromatic light source set consists of components including a 150W xenon lamp (ozone-less type), bundle optical fiber, and motorized direct movement type compact monochromator SPG-120-REV. The systems monochromatic light and changes the wavelength of the output light at high-speed.
The SPG-120-REV system enables acquisition of the spectral characteristics of solar cell materials, semiconductors, light detecting elements, fluorescent substances and other optical devices.
Free sample of LabVIEW2013 software is provided with the system for customers to install on their own PCs. The sample software enables the user to change of the wavelength of monochromatic light source. The software can be edited by users and stored on their PCs.
