Phosphor
Introduction:

EVERFINE provides the professional test and measurement instruments for phosphors and other luminescent materials, including spectra & color & photometric test system, Exciting spectra and the thermal quenching test system, Long afterglow material optical test system, etc..

 

1. Spectra & Color & Photometric Test System For Phosphor
Be applied for the photometric and colorimetric measurement for the YAG phosphor of white LEDs, and tri-band phosphor. The measurable items include the relative spectral power distribution P(λ), chromaticity coordinate, correlated color temperature, rendering index, SDCM, peak wavelength, dominant wavelength, average wavelength, spectral purity, red ratio, Spectral Half Width, etc. It meets the requirements of CIE standards.Besides, The system can offer ideal exciting source(λP=460nm, Δλ≈10nm), the spectrum of YAG phosphor can be obtained without the disturbance of the blue exciting spectra.

Welcome to contact Sales Center of EVERFINE for more details.


2. EX-1000 Exciting Spectra And The Thermal Quenching Analyzer For Phosphor
EX-1000 phosphor exciting spectra and thermal quenching analyzer can measure both excitation spectrum and emmission spectrum, which is benefit for choosing of efficient exciting source or improving the material itself to achieve high conversion efficiency. And some luminescent material (e.g. Phosphors in a electrical light source) actually work in a high temperature environment, thus measure these materials in their real state is much more reasonable than just in room temperature. EX-1000 provides above functions, and also be capable of total quantum efficiency measurement of phosphor.

3.Long Afterglow Material Optical Test System
CY-1000 long afterglow phosphor optical test system is designed according to relative Germany standard and Chinese standard requirements(EVERFINE is one of the Chinese National standard drafters),it is applied for analyzing and testing the luminous brightness and variation curve of afterglow phosphors.
