    Raman-spectroscopy

    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...

    B&W-tech Spectrometer & 473 module: Setup+Mods+Info

    @ 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

    B&W-tech Spectrometer & 473 module: Setup+Mods+Info

    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...

    Raman-spectroscopy

    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

    B&W-tech Spectrometer & 473 module: Setup+Mods+Info

    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...

    B&W-tech Spectrometer & 473 module: Setup+Mods+Info

    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...

    B&W-tech Spectrometer & 473 module: Setup+Mods+Info

    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...

    B&W-tech Spectrometer & 473 module: Setup+Mods+Info

    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...

    B&W-tech Spectrometer & 473 module: Setup+Mods+Info

    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.

    B&W-tech Spectrometer & 473 module: Setup+Mods+Info

    Hi Paul, I do agree with you, in point of view of diffraction, but in terms of focusing le light the thikness may play some role as the light path will be shorter ... don't you think ? and,. and 3mm (the one inside the spectrometer has 3mm thikness, and the one available has 6mm) over 20mm...

    Hi, can you tell me more about these replacement optics, please? C

    B&W-tech Spectrometer & 473 module: Setup+Mods+Info

    Dear Every one, For those that have changed already the grating. The grating in the Thorlabs link has 6mm thikness, do you think it will work fine, as the one inside the spectrometer is only 3mm think> Thanks for the help C
