Wooden Dark Box

The wooden dark box is a light-proof sealed chamber used to observe the optical properties of samples under specific light sources, such as color and fluorescence. Its principle is to isolate environmental light interference, with an internal configuration of a standard light source and neutral gray interior walls. It is applied in color difference comparison, fastness rating, and fluorescent substance detection for inks, coatings, and textiles.
Selection
When selecting, consider matching the chamber dimensions to the sample specifications, ensure the light source type meets the testing standard requirements, and position the observation window for ease of operation. A neutral gray coating on the interior walls ensures color evaluation accuracy, and attention should be paid to ventilation design and mildew-resistant material treatment.

Instruments
