Application Case Studies

In this area, we illustrate the many, varied applications for our equipment in the field of lasers, light source measurements, displays, LEDs and automotive lighting. We gratefully acknowledge the cooperation of our customers for their permission to publish this information.

Automotive Headlamp Beam Pattern Testing Ring Automotive is using a ProMetric™ CCD imaging photometer from Radiant Imaging with specially written application software to simplify the testing of automotive headlamp beam patterns in order to demonstrate the advantages of their high performance after-market bulbs and analyse the headlamp's illuminance performance against the requirements contained in the applicable ECE R20 standard. » Learn More

Illumination Design Through Whole-Sky Luminance Mapping University College Dublin is using a ProMetric™ CCD imaging photometer from Radiant Imaging to perform whole-sky luminance mapping, simplify the modelling of sunlight illumination and improve the lighting inside buildings. » Learn More

Instrument Panel Measurements Bentley Motors is using a Radiant Imaging ProMetric™ CCD imaging photometer to simplify the testing of automotive instrument panels and to ensure that the LEDs selected provide consistent illumination, create the required level of brightness (luminance) and emit exactly the desired colour. » Learn More

Intense UV Lamp Spectroradiometry The measurement of intense ultraviolet light sources was causing the barium sulphate coating on NPL's 2m integrating sphere to lose reflectance. Labsphere came to the rescue with Spectralon - a material with the highest diffuse reflectance in the 250-2500nm band that also exhibits extreme environmental and UV stability. » Learn More

Medical Laser Dosimetry Diomed produces a diode laser system designed for photodynamic therapy (PDT). The laser light is delivered to the patient via a cylinderically diffusing fibre tip. Measuring the output of the fibre for accuracy dosimetry would be extremely challening for a traditional radiometer. Fortunately, a Labsphere integrating sphere proved to be a simple solution. » Learn More

LED Forensic Illuminator Testing Foster & Freeman is using a Labsphere integrating sphere to measure the radiant flux of its LED-based illuminators that are used for forensic examinations at scenes of crimes. The integrating sphere proved to be the best device for capturing the large diameter, low power beams, proving yet again just what a versatile solution integrating spheres can be. » Learn More

LED Lens Efficiency Carco Technical Plastics (CTP) are a leader in the field of LED optics and have developed a range of high-efficiency lenses for use with the Luxeon range of high power LEDs from Lumileds. A Labsphere integrating sphere photometer provides CTP with a means of accurately measuring the photometric throughput efficiency of the lenses. » Learn More

Remote Sensing for Airborne Atmospheric Measurements Integrating spheres impart a near-perfect cosine angular response for accurate spectral irradiance measurements. The Met Office worked with Pro-Lite to develop custom Spectralon integrating spheres from Labsphere for use on its Facility for Airbourne Atmospheric Measurements (FAAM) ot help with improved weather predictions. » Learn More
