LED versus Incandescent Lighting

As the debate over LED versus incandescent lighting continues throughout a variety of industries, it seems there is less to deliberate within the color measurement industry; namely for use in densitometers and spectrophotometers. There are 5 compelling reasons for choosing a densitometer or spectrophotometer that uses an LED light source. LEDs last longer. In fact, LED’s can last up to 10 times longer than incandescent light; which translates into an average incandescent lamp life of…

What are M0, M1, M2, M3 Measuring Mode Settings

In accordance with the ISO 13655 standard, the “M” series of measuring mode settings were defined in order to standardize illumination conditions where optical brightening agents are utilized in substrates. The following is designed as a quick reference chart of the 4 different measuring mode settings within the “M” series. M0 “Color measuring mode A” spectral luminance factor without polarization filter under a light source that simulates standard illuminant A (gas lamps or LEDs, 2856…
