Dear all, Does any one have the PDF of about the manual adjustment and fine-tuning of the spectrometer? the official website of Science-Surplus is off now :( Thank you for the help. C

Hi Every one ! I think that one member of the firum has wrote a code to run the B&W Tek refurbished spectrometer. Can you please, help me to find the link ? Cheers C

Hi FlatBroke, I think that this is mostly a toy and made by a non professional. He is missleading, or in the best cases he ignores and does not know any thing about physics. This is what makes me think that it is a toy made by a hobbyist. he speaks about Raman and stellar spectra. It is...

Hi every one, I got one of the new model. I can tell that it is really much better than the first version. it is really more sensitive, i made a test wt my students to compare both models, we got 117 +/- 6 more sensitive than the previous model. It is more robust, it has a slit of 100um by...

Hi Brend, I think it is how the licence system works, it is when you get the license that the ThunderOptics option is activated. The best is you contact Friedrich, the developper of the software or see with ThunderOptics directly. I do not remember how it folded for me, just that after some...

Hi Hi Brend, I had the same problem, but you have t o uploadthe latest version, and get the license it costs 30Euros. Here is what i get : it is terrific, really to control the unit with thissoftware. Enjoy C

@ Kecked, You have in your description : BW TEK-2000nm/800nm/400nm moved gratings Do you mean that you have changed the grating of your spectrometer ? Thanks C

I see ... I have remouved all the slit with the three screws .. i had no tighny screwdriver ... So, i think that definitly, you are right, the problem is not in the filter but in the allignement of the slit. Many thanks for the precious help To my turn to share a news for those who are...

Yes it is a new, The spectrometer shows as ThunderOptics, and i was directed to them to buy the license. But really for 30Euros ... it is a veru good software @ Chloderic, I am going to put bac the filter tonight and see the allignement problem C

Hi guys ! a very very good news ! For a good Raman software, the Spectragryph software has been addapted to our BW Tek spectrometer. I got a licence for 30Euros and it is terrific have a look : https://www.effemm2.de/spectragryph/about.html C

Many thanks Chloderic four your answer, In fact, i was very very careful when i remouved the filter, and i am "quite sure" thatit is in its place, I was thinking that may be i had modified the "light path" when i remouved it. It is why i am asking if other have seen such effect? Also ... i am...

Dear all, I have been playing around with the spectrometers (i have 4, two that i have already burned ...) I took off the low pass filter and i saw that the spectrometer is no longer alligned and I have to re-alligne it. Did any one did this operation after remouving the lowpass filter from...

Dear Richard, I am sorry if i am that bad in electronics. Do you mean that with this PCB you just need the optical banch and this green PCB to make the spectrometer work and work better? can you, please, explane why you need this PCB board, is it just to make the spectrometer going fast? does it...

Hi Every one. Chloderic, as for the resolution, I think that you can not get more than that with the unit. I tried myself changing the slit and putting a thiner with no results. I contacted the guy of Science-Surplus if they can do some thing, he answered that they tried and it is the best that...

I want to change the grating, and i was asking if some one has done it before, and with which thikness he used (3mm or 6 mm) for the grating. As the one installed has 3mm, and those available in the market are 6mm.
