Many samples, including RNA, DNA and protein absorb UV which can be used to create contrasting images. The UV absorption imager transmits UV light through the sample and then detects the same wavelength UV light on the camera. Areas that absorb the UV light create contrast, enabling you to see differentiating features in your crystallization drops. UV absorption can be helpful for imaging drops that are not UV fluorescence, for example, DNA, RNA, and proteins without tryptophan.
