Motivation： We are dealing with piezo crystal products. We are considering new analysis technique that combining piezo sensor and spectrometer measurements. However, commercially available multichannel spectrometer is very expensive, $2,000-$4,000/p . So we decided to develop by our self.
System : In the measurement system, connect the PC and spectrometer via USB, and measurement software perform data acquisition and graph display.
Data can be saved as a text (csv) file.
In addition, initial calibration is performed at the time of manufacturing and shipping, it is possible for users to recalibrate easily.
Filters and slits can be changed arbitrarily by the user depending on the wavelength and intensity of light.
The spectrometer uses mirrors and diffraction gratings. The photograph shows that a spectrum with incidence of a Hg lamp. You can see green, blue and purple on the right side of the screen.
1, Pre-measurement is occurred to using Hg lamp* . Software using dummy Pixel No. and wave length. *Hg-Ar is better.
2. Result of pre-measurement gives true pixel No. and wave length.
3. To overwrite a calibration file. (column A; pixel No., column B wave length)
Structure : The internal structure consists of a spectroscope, a CCD sensor, and a PCB substrate.
-Spectrometer (slit, filter : customer's choice) x1
-Software (English or Japanese) x1
-Hex wrench x1
We are launched kickstarter project.
We think that it is important how to make results of experiments cheaply and quickly.
Commercial price of similar product is 2,000 to 4,000 USD/p but our target is within 600 USD/p.
Our spectrometer is useful for Physics spectroscopy, and main is immunoassay. (removing CCD cover, LED 260-280nm combination)
