Light Measurement & Photometry
|Lasers, Optics & Photonics|
Remote Sensing & Spectroscopy
Our products are used in many diverse applications. We are proud to share some of the more interesting uses to which our product are put in our case studies area.
Light measurement plays an important role in the development of automobiles, from the colour and brightness of interior and exterior lighting, to the beam pattern of headlamps and the brightness and colour of instrument clusters and displays.
Luminance, luminance uniformity, view angle, colour gamut, contrast ratio and mura (defects) are important metrics in judging the quality and performance of the next generation of LED, LCD and OLED displays.
Luminous flux, chromaticity, colour temperature, colour rendering and luminous efficacy are routine measurements in the development and manufacture of any type of lamp, from incandescent to tomorrow's ultra-efficient solid state lighting.

Sensor Arrays & Imaging Systems
LEDs and OLEDs form the basis of many innovative products, from large area video screens to ultra-efficient lighting. Important metrics include luminous intensity, luminance, luminous flux, luminance uniformity, chromaticity, colour temperature, colour rendering and view angle.
Standard "photometric" data for luminaires is based upon measurements of luminous intensity as a function of angle. From this, the light output ratio (LOR) is calculated and standard photometric files (IES, EULUMDAT) are generated.
Making measurements using light. From sunscreen SPF and UVA protection factor (both of which are derived in-vitro from spectral transmittance) to the reflectance of butterfly wings. Surface "appearance" is guaged by measuring BRDF or scatter.
Electronic imaging equipment based upon CCD and CMOS detector arrays requires pixel normalisation, flat fielding and distortion correction to yield high quality data or images. A similar approach is taken with remote sensing spectral imagers.
Signals & Signs
The correct brightness, luminance uniformity and chromaticity of signals and signs helps to ensure that the information or warning message is clearly communicated.
In-vitro spectrophotometry is routinely used to determine the sun protection factor (SPF), UVA ratio and COLIPA UVA-PF of new sunscreen formulations.
