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 use the small diameter optic. The light exiting the fiber optic is not intense enough. Currently, the light source is a deuterium lamp with a fiber optic connector port (black box with a port and an on-button,) but eventually the light will need to be collimated through a medium and focused back into the 10 micron optic. Is the only way to get a more intense light to have a more intense source, or is there a way to focus light into a smaller beam and make it more intense? Can I do it with lenses or do I need a stronger lamp? As far as I know, this deuterium lamp was not designed for a 10 micron fiber, but I also don't know if there would be a difference.
