Measurement Instruments for Luminous Intensity

Light measurements can be divided into a series of measurement principles, each of which is quantified according to different optical parameters. Photometric measurements, for example, are expressed according to the responses of the human eye. This is based on an averaged spectral sensitivity known as the Vλ luminosity function, which categorizes wavelengths of green-yellow light […]

Using Light- and Colorimeters for Spot Measurements

Modern displays are subject to optical variations at different stages in the production process. Colour and luminance quality can fluctuate due to light-emitting diode (LED) batch inconsistencies or quirks, but this does not necessarily constitute component failure. This could merely be a product of the rapid-throughput production cycles and the complex arrangements of LED backlights, […]

Outlining the Applications of a VIS Spectrophotometer

A VIS spectrophotometer is a quantitative tool for analyzing the visible spectral properties of a sample with outstanding degrees of accuracy. It can acquire the intensity of a light source at wavelengths of between 380 – 780 nm, with integrated processors capable of running independent calculations and providing rapid assessments of a lighting product’s spectral […]

The Capacities of Compact Spectrometers

The rapid pace of modern technological research, development, and manufacturing has altered the way many crucial processes are carried out. R&D measurements and quality control procedures are increasingly integrated into continuous production facilities to improve manufacturing throughputs and provide accurate product insights directly at the point of production. This requires instruments that are smaller, with […]

The 4 Most Common Spectrometer Applications

Spectroradiometers are used to separate, quantify, and analyze the spectral characteristics of a light source, providing industry-specific insights based on a light’s wavelength intensities or frequency. They use a grating to split light into wavelengths of different bandwidths and funnel that light through the spectrometer using integrated concave mirrors. These high optical throughput components ensure […]

What Causes LED Flicker?

Mains electricity for residential and commercial properties operates on the principle of alternating current (AC); the process by which an electrical current and voltage is periodically reversed in an oscillating motion known as a sine wave. The sine wave constantly moves from negative to positive values in association with the magnetic polarity of the alternator […]

Illuminance Meters for Professional Applications

Illuminance meters quantitatively measure the amount of luminous flux (lx) of incident light on a surface according to human perception; CIE 1931 function. This is crucial for the optical optimization of lighting designed to fulfill an environment’s ambient properties, for example for retail, offices, and workspaces. Illuminance measurements can be carried out to achieve a […]

The Importance of Light Measurement in the Display Industry

The display industry is characterized by persistent innovation and competition, as manufacturers strive to deliver the best possible user products. Various industry leaders field contending new display technologies such as QLED (quantum dot light emitting diode) and OLED (organic light emitting diode) displays in bids to provide the best consumer experiences and improve their own […]
