Achieve the most flexible setup with the combined cuvette holder, attenuator, and filter holder. The attenuation can be adjusted from 0% to 100% and securely fixed with a set screw for precise control. The cuvette holder accommodates any cuvette up to 10×10 mm, and the filter holder can hold half-inch diameter filters (12-13 mm) with thicknesses ranging from 1-8 mm.
