yes its the second one!
I looked inside and there are some lenses of some kind. I think they are design for a much bigger fiber though. My lab-mate thinks we need a high quality aspheric lens to focus the light into the tiny 10 micron fiber.
It looks like we're going to be using this lamp...
there might be a collimator or some lens inside the bulb. I do get some output from the fiber that I can read on the computer after the spectrograph, but it is dim. I guess if that's the case then I've answered my own question.
I'll keep fiddling.
thanks for the reply
yes, as far as I know, the optic is just pointed at the lamp, though I don't really know. It is a:
"High Power UV-VIS, Fiber Light Source" made by Hamamatsu
To me it's just a box with a connector port and an on-button. I don't really know the specifics (maybe I should start finding those out...
I hope this post in the appropriate forum.
I have a spectrograph and a CCD imaging chip that I am using for an optics experiment. The light coming into the spectrograph is through a 10 micron fiber optic. In order put the light on the CCD imaging chip the way I want it, I believe I need to...
HHO isn't a hoax...it's an H2 and O2 gaseous mixture.
The reason why the presence of hydrogen in small amounts would speed up the combusion process is because it supplies more H and O radicals, sooner, to react with the decomposing hydrocarbons and helps trigger the chain branching reactions...
