AT NEXT month’s LuxLive 2019 exhibition in London, Cambridgeshire-based Analytik is set to unveil a luminance-measuring device to test the compliance of emergency lighting products.
Luminance distribution and contrast measurements are of key importance in the verification of internally illuminated emergency exit signs in compliance with the IEC/EN 60598 series standard. Specific measurements must be performed according to the standard in order to check luminance uniformity across the safety sign, in addition to colour rendering index.
For this purpose, a significant number of points on each sign must be tested and compared.
Using a traditional spot measuring device for this task is time and labour intensive, and requires manual calculations and reports, whereas the imagining luminance measuring device provides a quick and reliable testing procedure.
The new GL Opticam 1.0 captures the whole image and analyses the luminance level and compare values. Users have quick access to data and immediate verification of compliance.
Indeed standards agency BSI has already pre-ordered one of the cameras to verify emergency lighting product compliance with the standard ISO 3864-2:2016 (Graphical Symbols – Safety Colours and Safety Signs Part 4: Colorimetric and Photometric Properties of Safety Sign Materials).
When asked why BSI selected the GL Opticam, global head of gas and electrical products, Graham McKay, told Lux: ‘The Opticam’s the only instrument available that’s able to meet all of our requirements and I am pleased with the ongoing support provided to customise the software to meet our specific needs.
‘Our investment with Analytik demonstrates our commitment to constantly improving BSI’s services and in finding new and more efficient testing procedures’.
Analytik’s light measurement expert Isaac Gilbert, said: ‘We’re really excited to have installed the UK’s first GL Opticam at BSI as the business standards company helps organisations make excellence a habit all over the world.
‘The Opticam is a unique high-performance instrument, which will enable BSI to precisely measure luminance across a wide range of applications’.
The GL Opticam is a designed for the quality control of indoor and outdoor lighting products, illuminated symbols, and automotive, aerospace and street luminance.
Equipped with a high resolution CMOS sensor, V-Lambda correction filter and a lens optimised for precise luminance measurements, the GL Opticam is capable of accurately replicating human response to brightness.
Analytik has over 15 experience in cutting-edge scientific instrumentation to leading organisations throughout the UK and Ireland. In addition to supplying innovative analytical instrumentation from global technology providers, it supplies specialised consultative expertise and comprehensive pre and post-sales support to ensure that our customers get the most out of their investment.
