Hey,
I'm now trying to install the DJ532-40 laser into the LDM21 cooler. As you can see in the pictures though, it doesn't seem to provide a very reliable fit (as the LDM21 is not directly compatible, as I understand). Should I try to scrape away the green material to allow the laser to fit? What ...

Hi,
now that CFL lamps are banned in Europe, and quite difficult to find, is there an alternative, recommended way of calibrating the spectroscope?
Thanks

Also, what about degassing the resin? Do you let it sit out separately, and then mix the two parts? Or do you mix it immediately, let it sit for a few minutes and then apply?

Hello,
sorry for a bit of a ridiculous question, as I might be overthinking the building process of the performance spectroscope quite a bit. However, I wanted to ask about gluing the grating to the 3D printed part... If I don't have access to 120um fishing wire, is it fine to just eyeball the ...

Hello,
I'm an electrical engineering student at university and me and a few other students are working on a project to build the performance ed. spectroscope (this is a requirement of our supervisor) with a linear 2d sample positioning system to create a map of the measurements. First of all, the ...

Hi, did you succeed in building this mapping stage? I'd love to hear more if so! Thanks
