The term haze is usually used to refer to the scattering effect of samples on penetrating light. It is hereby often not taken into account, that according to ASTM D 1003, haze is only defined for thin films used for laminated safety glass. As for films and thin sheets such as those used in displays, varying measurement set-ups often provides better signal contrast.
The LCRT-2005-S meter, in combination with the BTS-40-TRTH accessories, makes it possible to measure light transmission of the sample under different illumination conditions. This hence enables the user to determine the best measurement set-up for his/her specific application.
Detailed information on this measurement device can be found under LCRT-2005-S.
LED binning, in terms of the photometric and colorimetric specifications, requires spectral colorimeters that can ensure precise measurement values within very short measurement times synchronized with the process and that support fast data read out. The new BTS2048-VL from Gigahertz-Optik meets all the requirements for precise LED flash binning.
As stipulated by the EU Guideline 2007/23EG, a CE marking and approval by the so-called Notified Bodies are compulsory for pyrotechnic flares. Outside the EU, approvals by respective authorities e.g. the United States Coast Guard are obligatory. Logging of the Bengali flame in terms of its intensity and color is part of the test procedure. The BTS2048-VL spectral colorimeter is not only well suited for this application through its high measurement speed, but also through its compact housing with a tripod socket and its measurement optics that does not have susceptible light guides.
For more information on this device, go to BTS2048-VL.
Light and color characterization of Light Emitting Diodes is necessary during all phases of the production and configuration process. From single LEDs and matrices up to LED lamp and luminaires a universal measurement device supporting the different production steps would be the ideal quality control tool.
The Gigahertz-Optik GmbH BTS256-LED tester with its innovative modular design concept fulfills this requirement. In our ten minute product video all aspects of the LED tester are demonstrated with all optionally available attachments and software.
