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, automotive lighting and for the testing of sunscreens. We gratefully acknowledge the cooperation of our customers for their permission to publish this information.

Automotive Headlamp Beam Pattern Testing Ring Automotive chose a ProMetric™ CCD imaging photometer from Radiant Imaging with specially written application software to simplify the testing of automotive headlamp beam patterns. This allows the company to demonstrate the performance advantages of their high performance after-market bulbs. » 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, simplifying the modelling of sunlight illumination and improving the lighting inside buildings. » Learn More

Instrument Panel Photometry 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

Radiometry of LED-Based Forensic Illuminators 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

High Power LED Array Photometry A leading manufacturer of high power LED arrays chose Pro-Lite as its supplier of integrating sphere photometers and spectroradiometers. Interior access integrating spheres of 25 & 50cm diameter are used for accurate device characterision in R&D, while a series of customised 15cm spheres are used for high speed measurements in production. » Learn More

Testing the Efficiency of LED Optics 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 efficiency of the lenses. » Learn More

Luminaire Goniophotometry Pro-Lite was chosen to supply an innovative, compact, near-field goniophotometer system by Designplan, a leading manufacturer of light fittings and luminaires. Based upon a motorised goniometer stage together with a ProMetric™ CCD imaging photometer, the system is used to measure intensity versus angle, create standard photometric files (IES, EULUMDAT) and report light output ratios (LORs). » Learn More

Medical Laser Dosimetry Diomed designed a diode laser system for photodynamic therapy (PDT) in which the laser light is delivered to the patient via a cylinderically diffusing fibre tip. Measuring the output of the fibre for accurate dosimetry would be extremely challenging for a traditional laser power meter. Fortunately, a Labsphere integrating sphere proved to be a simple solution. » 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) to help with improved weather predictions. » Learn More

Sunscreen In-Vitro SPF & UVA Testing In-vitro testing allows manufacturers to develop new and improved sunscreen formulations and to bring products to market more quickly and at lower cost. Labsphere designed the UV-2000S to exceed the requirements of the latest COLIPA and Boots Star methods. Cutest Systems decided to invest in a UV-2000S to provide a fast and and cost-effective service to sunscreen formulators. » Learn More

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
