Optical Density Meter

A densitometer evaluates color depth or coating thickness by measuring the extent to which a material absorbs light of specific wavelengths. It uses a light source to illuminate the sample, and a detector receives the intensity of transmitted or reflected light to calculate the optical density value. It is applied in areas such as ink layer detection in printed materials, film image analysis, and uniformity assessment of plastic coloring.
Selection
When selecting, consider matching the measurement mode to the sample characteristics: transmission mode is suitable for transparent materials, while reflection mode is appropriate for solid surfaces. Ensure the measurement range covers the actual detection scope and the resolution meets precision requirements. Pay attention to the instrument's calibration method and repeatability indicators, ensure interface compatibility with existing systems, and verify that environmental adaptability aligns with the usage scenario.
