How is Objective Colour Measurement Achieved?

As the perception of colour can vary significantly from one person to the next, researchers developed the field of colorimetry, the science of objective colour measurement. In colorimetry, colours are measured as precisely as possible using colour measurement value systems. Analytical colour measurement techniques are typical in commerce, industry, and research, and are commonly applied […]

Measuring Flicker to Improve LED Lighting

Watch slow-motion video shot under artificial lighting, and you’ll likely notice that the lights pulsate or “flicker” at very a certain rate. Although at normal speed, this flickering cannot be seen, it still is a significant quality issue of lighting productions – particularly when it comes to LED lighting. To address quality concerns, there are […]

How an Integrating Sphere Functions

Integrating spheres are hollow spherical cavities with a highly reflective and white coating that are used to measure for example the power of laser light and total luminous flux from lamps. Integrating spheres are alike cosine correctors or lenses only optics and need a detector, like a spectroradiometer, connected and calibrated to it, in order […]

What is a Collimating Lens?

‘Collimating’ is the process of accurately aligning light or particles in a parallel fashion. For light measurement, this ensures that the light has minimal spread as it propagates. Collimating lenses are for examples attached to spectrometers, colorimeters or light meters to ensure that the light that enters the instrument is parallel and provide accurate readings. […]

Using Spectrometers and High-speed Light Meters to Monitor LED Performance

A light-emitting diode (LED) is a semiconductor light source that now finds use in a lot of applications due to its many benefits. LEDs use the effect of electroluminescence, which is where electrons recombine with electron holes and release photons when electricity is applied. The increased use of LEDs is due to its many benefits. […]

Outlining Imaging Applications of Test & Measurement Instruments

When talking about test & measurement instruments, there are many possible instruments we could be referring too. Generally, a test & measurement instrument is one that performs a specific test and outputs the measurement. Imaging applications that require light or colour uniformity to be measured benefit greatly from the combination of test & measurement devices […]

How Does a Spectrometer Work?

A spectrometer is a scientific instrument used to analyze the light properties of a luminous object or reflected light. The instrument measures these properties of light over a specific section of the electromagnetic spectrum. This blog post will outline the working principle of a spectrometer. The Components Within a Spectrometer For a spectrometer to operate […]
