Hello

Which wavelength do you need ?

Muayed Fadhil Abbas

You could use UV/ visible spectro photometer and there are many of them available. such device would measure UV absorbance as well as visible.

Wade Ellis

I agree that it is mostly a matter of finding a spectrophotometer that has a source that extends down to your desired excitation wavelength. There should be many on the market.
