NPL's 2m Spectralon Sphere 

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.

Diomed Laser Fibre 

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.

Foster & Freeman LED Crimelite 

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.

Met Office/FAAM BAe 146 

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.
