WOW Paul, that is good, please which grating and slit is in yours ? What do you thin about this ... ...

Which resolution is possible with the ocean optics ?

Great again , thanks for sharing !

I do not want a bigger spectral range , for the usage in this case 150nm may be enough. But i am searching a way to realize a better FWHM than the actual 0.8 nm. With a grating 600\mm IT would be only about 2nm. I have a concave toroid grating 44.7 x 44.7 mm with a focus of 100mm , but to use...

Hi Elektrotechniker, what do you think, what would be the total best complete price for this for shipping to me (here in Germany)

Hi, what do you think, does it makes sense to try to tune the resolution of this spec below the reached 0.8nm , what could i do ... ? I have no additional idea without bigger changes ...

Nice colour, but out of my possibility...

Thankx for sharing your work with us, interesting!

For those of you, who have an ocean optics usb spectrometer i found a free software to examine gem. It should run with Ocean Optic’s OmniDrive Link: www.gemmoraman.com/Downloads.aspx I have no such device and can not test it ..... maybe Paul ?

Hi Paul, since the systemsoftware here changed, you need no imgur to implement pictures in your post. I did it in an other way in my last raman posts: First i wrote the complete text in the box, than i uploaded all wanted pictures, than i marked the place in the text where to implement the...

Sorry for my question, what did you mean please, you have done it ? You changed the grating?

WOW, i missed something here ... ! Great

WOW

GREAT realy great ! Thanx

Yes Paul .... so it is .... not nice to do it and you may need some beer to do it .... and than ... it will not be easier.

Hello, In the next step, I significantly increased the efficiency of the assembly. For this I had to find out which type of lens is most suitable for this compilation. So that the comparison can take place under the same conditions I replaced the last used lens objectiv by a used microscope...

Hello, the entire project is considered in detail quite complex and therefore not in a slip here to describe. So I apologize for the fact that there are quite a few individual postings here, but even the processing of all descriptions is associated with a lot of work and the number of pictures...

Hello everybody, it goes on, next it was now necessary to get different filters under, in principle the inventor of the ucube actually provided the six side walls for this, as in the way as I have already shown with the IR filter. There are also solutions for mountings on the side walls for...
