The CUV-UV/VIS cuvette sample holder is designed for transmission and fluorescence measurements using a 10 x 10mm cuvette. It can be used in the UV/VIS and NIR range and features adjustable clamps to hold non-uniform cuvettes at a repeatable location.

The CUV-UV/VIS comes with two collimating lenses with adjustable focus to maximize the light throughput, apart from a 5mm wide slit for filters and a cover to prevent ambient light entering the light path.
