The Cheapest High Quality USB Spectrometer
Wavelength range from 350nm to more than 820nm (+/- 15nm)
No longer spend hundreds of dollars to enjoy your hobbies! to get a real spectrometer …
After selling the basic low cost Mini USB Spectrometer, and after lot of requests from our customers to build a more sensitive spectrometer with an optical fiber connector (SMA 905) … we have the pleasure to present Tafat Spectrometer.
(Please for a full review of the spectrometer, visit this blog :
https://physicsopenlab.org/2021/06/11/thunder-optics-spectrometer-spectragryph-2/
)
The actual model has 1200 Pixels and more than 100 times more sensitive than the Mini USB Spectrometer model.
It has a 100um slit in addition to the SMA905 connector. So, both modes are possible, you can use it with our the optical fiber, just orient the slit to the light source, or better, attache the optical fiber and collecte the light.
The spectrometer is sold with no optical fiber
.
You can also connect the second end of the optical fiber to a collimator (the we sell on ebay also, a Thorlab part that we sell at a high discount price)
Thanks to the quality of our instruments and parts, More and more educational and research institutions are using our instruments. This is the best recongnition of the quality and services we provide to our clients. We listen to our partners, and we build “sur mesure” the instrument they want.
Hundreds of Mini USB Spectrometers, tens of slits packs, hundreds of diffractions slides and much more other items are already solde via eBay or directly by CC or Bank transfert.
Please visit our webpage thunderoptics.fr to see the institution that are using our USB Spectrometers in their research of educational programs in the page “
They-trust-us-They-use-our-instruments
“
Once Plugged, run the FREE Software (There are two free softwares,download the software from the link you will get on the eBay bill) and start acquiring spectra and analyzing light from different light sources.
Actually, we offer for free a research grade spectrocopy software in some cases, please, contact us first.
We share with you some spectra taken with the Optical Fiber spectrometer, you can have an idea about the high sensitivity of the spectrometer by looking at the spectrum obtained of  the computer screen!!!
Also, the new model lets you have the solar spectrom (difuse light, the direct light will saturate the detector) lets you observe the atmospheric absorption lines of O2, H2O …
Don’t forget that you have to callibrate first the spectrometer with a known source, better and cheaper is the fluorescence economic lamp.
The spectrum of telecomand IR diode lets you see that our ;odel works very well also in the IR.
Look at the spectrum of the 532nm laser pointer … can you see the IR line?
With this USB Spectrometer you can do several experiments, for example:
1- Analyze the light emitted from light sources (see the attached image)
2- Transmission of filters (there is an example of a Clean Line filter and one for a Long Pass filter)
3- Absorbance / Transmittance of substances (oil, colored liquids … the last picture shows the absorbtion spectrum of Olive Oil)
4- Calibrate the spectrometer to calculate densities
This item in an analytical instrument, dedicated mostly for pedagogy and hobbyists (not for research!)
Our team will help you to use it and get the maximum from this scientific beauty
