Colors look different under various lights mainly because of metamerism—a phenomenon where two colors that match under one light source fail to match under another, caused by differences in the spectral composition of light.

Different lighting varies the color perception of objects. Warm light, like that from incandescent bulbs, tends to make colors more yellow, while daylight presents a bluish tint. Our color vision system plays a compensating role using a mechanism called color constancy.
Every light source emits light with a unique "spectral fingerprint" (i.e., the range and intensity of wavelengths it contains). This directly affects how an object’s surface reflects light and how our eyes perceive its color.
Our haze meters provide consistent and accurate data as per the requirements of ASTM D1003, ISO 13468, and JIS K7105. Due to the high precision, advanced optics, and automatic calibrations, haze meters produce repeatable and precise results for glass, films, and plastics while remaining simple to operate.
Lightbooths come in different dimensions. A typical tabletop model occupies 0.5-1 m². The bigger industrial variants take up 2-4 m². If you have special requirements, we can customize the product according to your size
Accurate readings can be obtained by keeping the sample clean, regular calibration, control of ambient light and appropriate measurement settings.
Colorimetry is a method that applies color intensity to ascertain the chemical concentrations. It is founded on Beer-Lambert Law, whereby the absorbance at a given wavelength is proportional to the concentration. It is popular in environmental and biochemical testing.
A CAC is a professional light booth designed to provide standardized lighting conditions for visual color assessment. It includes multiple light sources like D65, TL84, and UV.
When using a Pantone light box, each sample should be positioned flat and nearby the other samples, but not overlapping. Each one should also be in the middle of the light box, and the surfaces of the light box should be clean and non-reflective.
A haze meter should be calibrated every 6 months, or more frequently if used for certain quality control processes.
