What I want to do or know

I want to know if the webcam from v2.0 is suitable for spectrometer 3.0. Is there something else to have in account?

I'll remove the DVD piece and install it as described in v3.0.

Hi, Pablo - I think you can leave the DVD as it is, and the challenge will be to get it to remain in the same orientation with regard to the slit, very solidly, even though the cable comes out the back. The cable may be a problem because you won't be able to lay it against the angled wood block in the 3.0 design -- you may have to find a different way to support the camera, and that solid, unbending connection is very important to the calibration holding.

Thaks, Jeff. I'll try to use a wooden block with a hole in it, or made with pieces to allow the cable to pass. I'll keep distance and height from the lens to the slit.

What about the 45º and 60º degrees for the camera and the DVD of v3.0? Why do you suggest to leave it as it is already mounted? Not as important?
