Pro-Lite has published two brochures that describe its photometric measurement equipment for application such as measuring the colour and brightness of LEDs, luminaires, lamps and displays.
The Labsphere Spectroradiometer Brochure presents a range of integrating sphere systems that are used for measuring the total luminous flux of any size of lamp, LED or complete luminaire - sphere sizes range from 25cm to 3m diameter.
The NFMS Goniophotometer Brochure describes a near-field imaging goniometer system from Radiant Imaging that helps those working with solid-state lighting to save time and money by allowing them to generate standard photometric data for their luminaires in-house.
