Optional covers are available for 1 cm pathlength CUV-series cuvette holders. These covers fit over the sample chamber to block ambient light from the sample. Standard and “tall” versions are available.

Also available for use with CUV-series fluorescence cuvette holders are mirrored screw plugs, which are inserted into a collimating lens port on the cuvette holder to redirect energy to the sample or collimating lens.
