A goniophotometer is a photometer for measurement of the angular dependence of optical quantities. It is applicable to acquire the luminous intensity distribution, luminous flux, spatial color distribution, and luminance distribution of lamps and luminaires. The latter two are proposed in recent years as the development of light & lighting.
Luminance meter is designed for the luminance measurement. Luminance colorimeter and spectral radiance meter are also capable of spectra and color measurement. They are widely used in the measurement of LED / LCD / CRT / OLED display, backlight panels, traffic lamps, automotive lamps, instrument panels, indicator lamps, lighting engineering, etc.
EVERFINE provides wide range of illuminance meters. The pocket illuminance meters suit best for field measurement, while the desktop illuminance meters are very good at lab measurement.
The UV Radiation from 100nm to 400nm is usually divided into UV-A (315nm-400nm), UV-B(280nm-315nm) and UV-C(100nm-280nm). UV radiometer is specially designed for the UV irradiance test, and mainly used to evaluate the impact of UV radiation on humans and other biology.
The Aging & Life Test System for LED Products are widely used for normal /accelerated aging, lumen maintenance measuring, lifetime evaluation and temperature characteristic testing for LED products including LED package, array, module, and luminaires. The extrapolation of lifetime by programmable models is also available to estimate the lifetime of LED products.
EVERFINE offers the Thermal analysis systems including the measuring of junction temperature and thermal resistance. They are fully meet the requirements of JESD-51,GB/T 4023,SJ20788-2000,QB/T 4057,etc.
The system is designed especially for the determination of optical radiation hazard exposures specified in IEC62471, such as actinic UV hazard exposure for the skin and eye, near-UV hazard exposure for the eye, retinal blue light hazard exposure, retinal thermal hazard exposure, thermal radiation hazard for eye and skin, for LED products, UV-lamp, lighting sources, luminaires and etc.
EMC(Electromagnetic Compatability) testers are specially designed according to the characteristics and requirements of EMS(Electromagnetic Sensitivity) test for LEDs and other electrical appliances.
